Consider the histogram shown here. it includes all daily average January temperatures observed at #UVic (2002–2026). Extreme events are rare events, by definition. Notice that that while there are a small number of extremely cold days in the record, much farther out than 3 standard deviations (-8 °C is about 3 standard deviations from the mean) there are no similarly exceptionally warm days. This is because the rare really cold days are caused by so-called arctic outbursts, very cold air flowing south and west from the continent. There is not similar mechanism for hot days, yet.

Rain at #UVic in January was a bit above average 114 mm versus 95 mm. We observed some activity at the rain gauge on 22 days (versus 19 days). However, a number of the single rain gauge tips, about 0.25 mm were due to dew and frost, and collection from some heavy fogs. By coincidence, on the last three days of the month, we recorded the same amount of rain, 3.8 mm. There was no snow observed last month. 4/ #Saanich #VictoriaBC
