June 2026

And so we've reached the end of a fairly historic June. Let's take a big look back at Edmonton weather.

It's perhaps unsurprising given all the rain, but June 2026 was quite cool.

The average High of 19.5°C was the 122nd warmest out of 147. That's around the same as 2013 & 2011.

On the other hand, the average Low of 10°C was actually 35th warmest.



High Temperatures

June's Highs ranged from 10°C on the 1st to 25.9°C on the 14th. 12 Highs were above average. and 18 were below average. The 1st & 2nd were the coldest in 30+ years.

June averages 18 Highs above 20°C, and 2026 only had 15. 

And on average 5 of those get to 25°C, and 2026 got 5. 

It's a little weird that the Highs made this a bottom-25 year, because it was honestly pretty unremarkable.



Low Temperatures

For Low temperatures June 2026 had 10 above the 30-year average (which is still much higher than the long-term average), and 20 below. They ranged from 6.6°C on the 23rd to 15.1°C on the 25th.

June Lows usually don't have much of a spread. We average 2 above 15°C, and 2026 had 3 (2023 had 12). And about half of the time we will get a Low below 5°C, but 2026 had none (2024 had 4).



Warm & Cold Months

June's Highs get a blue dot. The average of 19.5°C was -1.3°C cooler than the 20th century average, and close to 2013 & 2011. 

The Lows are a pretty typical orange. 10°C is 1.4°C warmer than the 20th century average.



The Horserace

Halfway through 2026 and our average temperature is the 29th warmest on record, and 0.92°C above the 20th century average.

Almost all of that was due to our January & February heatwaves. Since then we've mostly been pretty average.



Across Canada

Across the country June was a little cool on the prairies, and a little warm everywhere else.

The Highs ranged from 2°C above the 20th century average in Victoria, to -1.3°C below in Edmonton & Calgary.

For the year so far Kelowna Highs have been its 3rd warmest, Victoria is 9th, and Vancouver is 14th.

For everyone else the first half of 2026 has ranged from top-25 to top-70.



Precipitation

And now...precipitation!

June is usually our 2nd rainiest month, averaging 78mm. But wow, June 2026 really showed off. 

Blatchford ended up with 269.1mm, Stony Plain got 256.3mm, and the airport got 222.5mm.

Our record for June had been 216.5mm, from 1914. But 2026 blew that away. 

And our rainiest month ever recorded was 282.5mm, in July 1901. In the end 2026 missed that record by just 13.6mm. But it sits comfortably as our 2nd rainiest month on record.

June and July average around 15 days with rain. June 2026 got 20 rainy days at Stony Plain, 19 at Blatchford, and 18 at the airport.

By the end of June we average around 208mm of precipitation for the year. 

The rainy June pushed Blatchford to 392mm, Stony Plain to 375mm, and the airport to 314mm.

In a full year we get around 430mm of precipitation, and June 2026 just delivered 2/3 of that.

This is our peak storm season, and we got several 30mm+ days. The largest were June 21st with 73.3mm at Stony Plain and 63.8mm at Blatchford. The airport had an underachieving 45.9mm.

Blatchford's 63.8mm was its 11th rainiest day on record.

For Stony Plain's 73.3mm day, it had only ever had 7 days that big, the airport has had 1 (in 1990), and Blatchford has had 5 (most recently in 1990).

Blatchford got 105.7mm over the 3 days from June 20-22. That's only the 6th time that has happened at Blatchford.

And Stony Plain's 2-day total for June 20-21 was 123.2mm. That's only happened twice before, in 1953 & 1937 at Blatchford.

Edmonton's 380mm of total precipitation might feel impressive, but at the end of June Halifax & St. John's are both over 700mm. And while we had a record-breaking June, in Calgary their 104mm was just a bit above average.

For big storms it's not often that we see Edmonton leading the pack, but here we are.

Our 63.8mm was ahead of Regina's 57.5mm. And our monthly total was more than 100mm ahead of anyone else.



The River

With all the rain the river saw 2 nice little bumps up to around 6.5m & 1,300m3/s. 

That's a fairly typical summer peak, similar to 2024 & 2023. 2020 got to 8m & 1,900m3/s, and 2013 (Calgary's flood year) got to 9.2m & 2,850m3/s.



July

For July, the average High is about 23.5°C. Around 25 days reach 20°C, including about 10 at 25°C. Most Julys will get at least one 30°C day, but recently 2020, 2019 and 2016 didn't. July is also usually (usually) our rainiest month, with an average of 90mm.

May 2026 Review

A late frost, a later heatwave, and an even later start to our monsoon season!

All that and more, as we take our big look back at Edmonton weather for May 2026.

May 2026's average High of 20.1°C was the 16th warmest on record. The average Low of 6.8°C was 18th.

Compared to recent years that's close to 2025, 2024 was pretty cool, and 2023 was our warmest May on record by far.



High Temperatures

May's Highs ranged from 9.9°C on the 15th to 30.5°C on the 29th.

Overall 23 Highs were above average. 8 were below average, at the start, middle, and end of the month.

May averages 2 Highs below 10°C, and 2026 only had 1 with 9.9°C on the 15th. 

On average 10 Highs get to 20°C, and we got 15.

3 of those get to 25°C, and we got 6. 

And we had 2 Highs get to 30°C. Recently 2025 had 3, 2022 also had 2, and 2016-2019 all got to 30°C.

Our hottest day of the year usually happens in July or August. But since 1880 there have been 18 years where the hottest day occurred in May. Recently that included 2019 (30.6°C), 2016 (30°C) & 2010 (30.3°C).



Low Temperatures

For Low temperatures May 2026 had 19 above average and 12 below.

That ranged from 14.6°C at the end of the month, to some frosty -2.3°C and -2.7°C nights earlier.

May averages 2 below-freezing Lows. And we got 2, on the 5th and then pretty late on the 17th.

About a quarter of the time May is frost-free, and recently that happened in 2024, 2023, 2020, 2018, 2017...



Final Frost

The average date of Blatchford's final frost is May 5th. 

2026 was a little late, dragging it out to the Victoria Day Long weekend on May 17th. That was one day later than 2025's May 16st. 

But 2024, 2023 & 2020 were all done around April 20th.

Around the neighbourhood Stony Plain's final frost was also May 17th, when their average is May 10th. The airport and Campsie were May 21st, although both of those stations could still see frost in June.



Warm & Cold Months

After a meh March and a cool April, May 2026 gets a medium orange/warm bubble.

The average High of 20.1°C was 2.6°C warmer than the 20th century average. The average Low of 6.8°C was 2.1°C warmer.

Back in 2014 we were below average from February through June.



Across Canada

Across the country May was mostly above average, except in Ontario & Quebec. 

That ranged from Kelowna's Highs 3.8°C above their 20th century average, to Quebec City at -0.8°C below theirs.

For final frost across the prairies, Edmonton's average is a week or two earlier than the other cities.

But in 2026 everyone was done within a few days of the May long weekend, unless another late frost sneaks in.



Snow

In May we average around 5cm of snow, but 2026 was snowfree.

May is snowfree around half of the time.

We average around 120cm of snow in a winter. This winter the airport was a little high with 133.5cm. But 60cm of that was all in December. 

Uncas near Sherwood Park is the only other local station which records snow. It got to 186cm after it has a very snowy April.



Snow Across Canada

Of the cities with snow measurements, the only ones to record snow in May were Calgary, Halifax and Moncton.

St. John's finishes the winter at the top with 522cm, followed by Charlottetown with 305cm. Then a bunch of cities are grouped around 200-250cm.



Precipitation

In May we average around 50mm of precipitation.

Our summer monsoon season usually gets started around mid-month, but this year it waited until the very end.

Blatchford ends up with 33mm, the airport with 26mm, and Stony Plain with 27mm.

In terms of storms it was a very quiet month...right up until the 31st dropped 22mm onto Blatchford, the airport, and Stony Plain. (Campsie 100km NW only got 12mm.

By the end of May we average around 125mm of precipitation for the year. After a low May, but an above average March & April the local stations range from 92mm at the airport to 122mm at Blatchford.

For total precipitation for the year so far St. John's, Halifax & Charlottetown are all way out around 600mm. For Charlottetown that's pretty high, but for the others it's normal.

Nothing is particularly exciting, but the prairie cities are mostly a little below average.

For big storms Toronto got 43mm on the 23rd, and Moncton got 34mm on the 3rd.

Halifax, Charlottetown, Quebec City, Montréal and Edmonton all got 20cm+ days.



June

In June usually about half of the Highs are above 20°C, with maybe a week above 25°C.

The last time that Blatchford had a June frost was 1942.

But we've had snow in June in 2011, 1967, 1922 and 1888.

April 2026 Review

So we've reached the end of March 2026 and it's time for...wait, what?? That was actually April?

Oh. Hmmm. 

Well then, I guess it's time for our big look back at Edmonton's weather for March April 2026.

So yes, April 2026 was cold.

The average High of 8.3°C was the 111th warmest on record. The average Low of -2.6°C was 105th. 

That's in the same range as 2020 & 2018, and warmer than 2013.

And that's about 6°C warmer than a typical March.

April is a rare month (along with October) that hasn't warmed up much over the past century.

Its average Lows have crept up by 2°C, while its Highs have actually gotten slightly colder.

In comparison, January is up by 8-10°C, and even July is up by 2-4°C.



High Temperatures

April's Highs were all over the place, ranging from 23.3°C on the 30th to -2.1°C on the 25th (our 3rd coldest on record). 

Overall 11 Highs were above average. 19 were below average, and 3 of those were the coldest in 30 years.

April 2026 had 3 Highs get to 20°C, when we average 2. But April also averages 16 10°C Highs, and we only got 11.

It had 2 below-freezing Highs, which is average. But one of those was in the final week. Recently only 2013, 2008 & 2005 got that cold, that late.

A "funny" thing about this spring is that it just hasn't been able to string together more than a few warm days in-a-row.

January had 6 5°C Highs in-a-row, and February had 12.

But since spring started we've only had a few here or there, then a 6 day stretch, and then freezing temperatures again. So winter felt more like spring than spring has.

This is just a comparison of the March-April Highs from 2026 to some of our colder recent springs, like 2020, 2013 & 2002.

2002 had our 2nd coldest March-April on record, and the average High was 5°C colder than this year.



Low Temperatures

April's Lows didn't have a huge range, from -8.5°C on the 1st up to 2.9°C on the 20th. 

Overall 12 Lows were above average, and 18 were below, including 4 which were the coldest in 30 years.

April averages 14 above-freezing Lows, and in 2026 we only got 6. 

Sometimes April starts off really cold, like -21°C in 2020 & -18°C in 2020. While 2026 wasn't warm, its coldest Low was only -8.5°C.



Final Frost

The average date of Blatchford's final frost is one week away, on May 6th. 

2025's was pretty late on May 16st, while 2024, 2023 & 2020 were all done around April 20th. 

Stony Plain's average is May 10th, while the airport's is May 25th.



Warm & Cold Months

April 2026 gets a medium blue/cold bubble, because the average High of 8.3°C was -2.3°C colder than the 20th century average. And the average Low of -2.6°C was -1.2°C colder. 

So April & March weren't warm. Other years with cool springs were 2020, 2018, 2017, 2014, 2013...



Across Canada

Across the country April was cold on the prairies (and St. John's), and warmish everywhere else.

That ranged from Saskatoon with Highs -3.7°C below their 20th century average, to Kelowna at 2.6°C above theirs.



Daily Highs on the Prairies

As much as Edmonton's spring has been underwhelming, all of the prairie cities have been pretty chilly. Since the start of spring Saskatoon has set 3 record for coldest daily Highs.



Snow

April averages 13cm of snow, and we almost always get at least a bit.

2026 was just above average with with 14.8cm.

But April had 9 days with snow, when the average is only around 5.

By the end of April we average around 113cm of total snowfall.

This winter we're up to 133.5cm, which is our snowiest winter since 2018's 160cm.

Almost half of this year's snow was the 60cm from our very snowy December.

Everyone wants the snow to be over, but in May we do average another 5cm.

About half of the time May is snowfree. The other half will usually be done around the first week, but 2011 waited until June 4th.



Snow Across Canada

This messy chart is the snow totals across the country. 

St. John's is way out in the lead with 522cm, while its average is around 330cm. 

Charlottetown was next with 305cm, while its average is closer to 500cm. 

Toronto's 190cm was its 11th snowiest winter.

After a quiet start to winter, Calgary got 47.8cm of snow in March (7th snowiest) and 37.2cm in April (19th snowiest). Together that's their 5th snowiest March and April on record. It brings them to 148cm for the winter, which is right on average.

The biggest snow day of April 2026 was St. John's 18.6cm on the 4th, followed by Calgary's 15.2cm on the 2nd. Edmonton's biggest day was 5.4cm on the 7th.



Snowdepth

For snowdepth, the airport and Stony Plain both got to 0cm on the 9th, but then bounced back up for a few days after that late storms. Blatchford got to 0cm on the 20th, and Elk Island finally got there on the 29th.

It's tough to remember now, but the snow got a really late start this winter, waiting until November 28th.

But the final melt was about as late as we get, along with other late years like 2020, 2018 & 2013.

Across the country most cities hung onto their snow into April this year. So while Edmonton was late, we had lots of company.



May

For May we average a week or two above 20°C, and quite often we will reach 30°C.

About a third of the time our final frost is in April, but May often has a few of frosty nights.

And the airport recorded May snow in 2024. 2022, 2021, 2020, 2019, 2015...
