July 2026 Summary

A hot July with average precipitation

The month started out really warm, with the average high for the first 14 days coming in at almost 30°C.  The second half was a not quite as hot, resulting in the overall temperature being one degree above average.  Also, if it wasn’t for a couple of days in June of last year, the 34.2°C on the 14th would have been the warmest temperature in the region since July of 2000.

There were only 7 days of precipitation during July, this is the least since 2001.  However, there were two really wet days (23.2 mm on the 9th and 47.4 mm on the 21st) so the total of 77.6 mm was only a bit below the average of 83.7 mm and within the average range.

Even with this month being less than average, the total precipitation so far in 2026 of 601.0 mm stayed above the average of 509.0 mm.  

Summary for August 2026:

Maximum Temperature 34.2°C
Minimum Temperature 8.4°C
Average Daily High Temperature 27.7°C (Long term average 26.6°C)
Average Daily Low Temperature 16.0°C (Long term average 14.9°C)

June 2025 Summary

June was wet with average temperatures 

There were a few hot spells in June along with a few cooler spells, while the warmest day came at the end of the month.  All of this resulted in an overall temperature just 0.2 degrees above average, well within the average range.

An interesting reset came when the temperature started at 27.3°C in the afternoon on the 13th and went down almost continually until the morning of the 15th reaching a low of 8.1°C. 

The two wettest days of the month were the 17th and 18th when 13.2 mm and 29.6 mm of rain came down.  This helped to put the total for the month of 102.0 mm ,well above the average of 71.0 mm.  It also resulted in the total precipitation we have seen in the first half of the year of 523.4 mm going even further above than the average total of 416.1 mm.

May 2026 Summary

A dry and cold May 

It was cold for the first half of the month followed by a few hot days in the second half.  But these hot days couldn’t make up for the proceeding cold and the overall temperature was more than a degree below average.  This made it the coldest May since 2020.

The temperature last went below zero on May 12, which is about 5 days later than the average date in the history of the Soulis memorial weather station. 

The only really wet day in May was the 25.6 mm on the 23rd, apart from that there was only one more day of more than 10 mm.  Consequently, the total for the month was only 55.2 mm, which is much lower than the average of 73.1 mm.

After a few wet months, this dry month brought the total for the year at 421.4 mm, closer to the average of 340.2 mm.

Summary for May 2026:
Maximum Temperature 29.1°C
Minimum Temperature -1.5°C
Average Daily High Temperature 17.7°C (Long term average 19.2°C)
Average Daily Low Temperature 6.5°C (Long term average 7.3°C)
Total Precipitation 55.2 mm (Long term average 73.1 mm)

April 2026 Summary

 A warm April that was the wettest in 15 years

There were warm and cool waves during the month, but overall the warm temperatures won with an overall temperature a little more than one and a half degree above average.  The longest streak of warmer temperatures were in the middle of the month with almost a week close to 20°C.

Nearly 100 mm of precipitation fell during the first half of the month, the second half was drier, but the total still came in at 130.4 mm.  This made it the sixth wettest April in history of records in the region and the wettest since 2011.

So far in 2026, we have had three of the four wetter than average months.  As a result, the total for the year of 366.2 mm is well above the average of 264.4 mm.

We got 2.0 cm of snowfall during April putting the total at 241.5 cm.  This means we are (probably) ending the 2025-26 snowfall season as the third highest in the region (and of course much higher than then the average of 159.7 cm).  

Summary for April 2026:
Maximum Temperature 22.1°C
Minimum Temperature -7.6°C
Average Daily High Temperature 13.4°C (Long term average 11.8°C)
Average Daily Low Temperature 2.6°C (Long term average 0.9°C)
Total Precipitation 130.4 mm (Long term average 76.4 mm)

March 2026 Summary

A warm March with the most precipitation in 15 years

The month of March had a week of warm temperatures at the beginning of the month, two very warm days, and very few colder days.  The result was an overall temperature that was more than one and half degrees above average, making it the first warmer than average month since last October.

During the last days of warm temperatures, the annual weather station contest ended at 3:45 pm on the 30th when the temperature first hit 20°C. Congratulations to the contest winner Sarah Nichol.

There were three really wet days during March including over 35 mm on the 31st.  The total for the month was 128.2 mm, almost double the average of 65.8.  This was the wettest March since 2011 and the sixth wettest in the history of records in the region that go back to 1914.

After a strong start to the snowfall season, there were only 13.5.0 cm, about half the average of 26.5 cm.  This makes the total for the snowfall season at 239.5 cm, clearly well about the average of a typical season of 159.7 cm.  For now this is the third highest total for a single snowfall season in the region, but of course there can still be snow in April.

Summary for March 2026:
Maximum Temperature 20.4°C
Minimum Temperature -19.3°C
Average Daily High Temperature 6.5°C (Long term average 4.4°C)
Average Daily Low Temperature -4.1°C (Long term average -5.3°C)
Total Precipitation 128.2 mm (Long term average 65.8 mm)
