Since I had April’s data loaded into Google Gemini AI, here is the temperature summary for this year compared to the last 14 years.
By calculating the average of the daily mean temperatures (TEMP) recorded in the sources for each April, the years in Didsbury, Alberta, rank as follows from warmest to coolest:
- 2016: 8.5°C
- 2015: 6.0°C
- 2025: 5.5°C
- 2024: 5.4°C
- 2023: 4.9°C
- 2021: 4.8°C
- 2026: 4.6°C (Based on data through April 24)
- 2019: 4.6°C
- 2017: 3.9°C
- 2014: 3.7°C
- 2020: 2.2°C
- 2022: 1.8°C
- 2013: 1.4°C
- 2018: 0.6°C
Key Insights from the Mean Temperature Data
- Warmest Year (2016): This year was significantly warmer than any other on record, largely due to a massive late-month heatwave where temperatures reached 29.7°C on April 19 and only dropped below freezing on 11 nights.
- Coolest Year (2018): Despite having fewer total freezing nights than some other years (19 nights), 2018 was the coolest overall because of an extreme cold snap early in the month where daily mean temperatures were as low as -14.1°C.
- 2026 Comparison: Through the first 24 days, 2026 is tracking very similarly to 2019 and 2021, which both saw a mix of early-month freezes and mid-to-late month warming.
- Standard Cold Baselines: In the coolest years (2018, 2013, 2022, 2020), the low monthly mean temperature is driven by persistent daytime freezes (Max ? 0.0°C), which occurred between 4 and 9 times in those specific years
