March 2018 Summary


A cool and dry March

The temperature during March was pretty steady throughout the month, however as the temperature typically goes up by about 6 degrees from the beginning to the end, that means the overall temperature ended up about 0.4 degrees below average.  Although it is less than average it is still within the average range.

One interesting thing was we didn’t see any extreme temperatures, the highest temperature of 9.3°C was the lowest since 2001 and the lowest temperature of -10.7°C was the highest since 2000.  This 20 degree range compares to an average range of 35.8 degrees and is the 4th lowest range in the 100+ years of weather data in the region.

With a streak of 10 days with no precipitation (and a week before that with very little) it isn’t surprising that it was a below average month for precipitation with only 40.0 mm compared to the average of 61.0 mm.

There was only 9.5 cm of snow which is only about a third of the average for March of 26.5 cm.  That brings the total snowfall to 100.5 cm, much less than the average of around 150 cm for the end of this month.


Summary for March 2018:
Maximum Temperature 9.3°C
Minimum Temperature -10.7°C
Average Daily High Temperature 2.7°C (Long term average 3.6°C)
Average Daily Low Temperature -5.5°C (Long term average -5.6°C)
Total Precipitation 40.0 mm (Long term average 61.0 mm)

(Long term averages based on 1981-2010 data for the Waterloo-Wellington Airport)

February 2018 Summary


A warm and wet February

The first half of the month was a bit colder than average, however the heat really kicked into gear in the second half resulting in an overall temperature that was a little over 2 degrees higher than average.

Within that second half was the high of 15.6°C on the 20th that was the highest February temperature we have seen in the over 100 years of weather data in the region.  Of course that might sound familiar as the previous highest February temperature was just last year when it got up to 15.1°C.

It was the wettest February in the last 5 years with 84.0 mm compared to the average of 54.9 mm.  About half of the monthly total came during 2 really wet days (19th and 20th) when a total of 38.8 mm of rain combined with warm temperatures to melt almost all of the snow that was on the ground.

Before that rain, we saw 25 cm of snow during the first half of the month which is close the average for February of 30.3 cm.  That brings the total snowfall to 91 cm, which is now getting farther behind the average of 125.6 cm for this time of year.


Summary for February 2018:
Maximum Temperature 15.6°C
Minimum Temperature -21.6°C
Average Daily High Temperature 1.5°C (Long term average -1.2°C)
Average Daily Low Temperature -8.1°C (Long term average -9.7°C)
Total Precipitation 84.0 mm (Long term average 54.9 mm)

(Long term averages based on 1981-2010 data for the Waterloo-Wellington Airport)

Happy 20th Birthday to us!

We officially launched the University of Waterloo weather station on Feb 27, 1998. If you want to see what the webpage looked like in the early years you can see it here.

Thanks to everyone who has helped make the station possible for all these years and of course thanks to everyone who uses and enjoys the station.

Be sure to join us for the 20th anniversary talk on Monday (see the details here).

20th Anniversary of the UW Weather Station Lecture


It is hard to believe, but the University of Waterloo Weather Station has been giving the public up to date weather conditions for 20 years! (Not to mention an archive of every reading ever taken as well as the popular contest to guess when the temperature first goes over 20 C). 

To mark this milestone, join UW Weather Station Coordinator Frank Seglenieks as he gives a presentation recalling how it all got started, the hurdles we have had to overcome, what trends we have seen in the data, and what we have learned along the way. There will also be a chance to ask questions about everything you have ever wanted to know about the station.

Tickets are free, but please register here so we can get an idea of how many people we can expect.
