There was a short, extremely hot one from the 7th-11th, and then a long, still really hot one from the 15th-23rd:

73.9°C
Before we get to the heat, think back to January which had a historically cold deepfreeze. It wasn't super-long like 2019, but it was extremely cold. It did some things that we hadn't seen since the 1960s or 1950s:
Top 10
- July 10th's 36.2°C tied 2021 for #4.
- July 18th's 35.3°C ranked as #8
2021 & 2024 combined have 5 of the spots in the top 10.
2021 & 2024 combined have 6 spots in the top 10.
Hot Highs In-a-Row
So many streaks.
Hot Highs In-a-Row
The most notable was probably 7 Highs in-a-row of both 30°C & 31°C, which tied 2021's record.

- 2 at 34°C (3rd longest)
- 3 at 33°C (2nd longest)
- 2 x 3 at 32°C (2nd longest)
- 8 at 29°C (tying 2021's record)

Records
With 9 records so far that ties 1910 for the year with the 3rd most record Highs.
The only years with more were 1934 with 10, and 1889 with 14 (it had a very warm spring).
2024 set 8 records for daily Lows in July, and had 2 more earlier in the year.
So 10 record Lows in 2024, 15 in 2023, 10 in 2022 & 12 in 2021.
That's 47 records in the past 4 years, or 13% of the year. Just for May-September 28% of the days have had record Lows.
Calgary
While Edmonton was well into the 30s, Calgary spent a bunch of July near 30°C.
Calgary
Their heatwave wasn't as extreme, but it did have some notable events:
- 4 32°C Highs in-a-row (2nd most)
- 8 30°C Highs in-a-row (tying 1917's record)
- 10 28°C Highs in-a-row (2nd most)
They also had 9 Lows in-a-row of 15°C, breaking 2021's record of 8.
Smoke
For posterity, it's worth remembering that forest fire smoke started to roll into Edmonton on July 19th. The heatwave continued until the 23rd, but the smoke likely supressed temperatures a bit.
And Calgary's all-time record Low on July 24th was an extremely smoky day.
