Winter 2008/09 Summary

A very wet winter with average temperatures

A very cold January was enough to offset a relatively warm February and March to put the entire winter season just a bit below average but still within the average range. It was 0.4 °C below average in the end with nothing particularly significant about the highest (16.6 °C) or lowest (-28.8 °C) temperatures seen during the season.

The trend of wet winters continued with 244.2 mm of total precipitation falling compared to an average of 184.5 mm. This makes 5 of the last 6 winters recording above average precipitation. The beginning of the season was very wet, it then levelled off, but some heavy rainstorms in the beginning of March put us well above average.

It is always awkward to just look at the snowfall during the 3 months of winter as opposed to the entire snowfall season that goes from September all the way to May. But a winter summary wouldn't be complete without it, so I will say we got 128.5 cm of snow this winter compared to the average of 106 cm, above average but not a record or anything. By the way we usually average about 13 cm for the spring.


Summary for Winter 2008/09:
Maximum Temperature 16.6 °C
Minimum Temperature -28.8 °C
Average Daily High Temperature -1.0 °C (Long term average -1.4 °C)
Average Daily Low Temperature -11.0 °C (Long term average -9.8 °C)
Total Precipitation 244.2 mm (Long term average 184.5 mm)
