September 2008 finished a little warmer and wetter than average, coming off a warmer and wetter than normal August. The mean monthly temperature at Winnipeg airport was 13.0C, or 0.7C above the 30 year average of 12.3C for September. (Sept 2008 averaged 13.3C at my site, 14.2C at the Forks) Temperatures averaged cooler than normal for the first week, then were generally near or above normal for the rest of the month. The highest temperature was a 29.2C reading on the 18th (29.6C at my site) while the lowest was -0.5C on the 27th, marking the official end of the growing season at the airport site. Elsewhere across the city however, September remained frost free with a monthly low of +1.4C at my site, and +3.4C at the Forks downtown. As a result, most flowers and gardens were still in bloom by month's end. Rainfall for the month was above average at 77 mm (82 mm at my site - average September rainfall 52 mm) but that was mainly due to two main rain events on the 1st, and the 22-24th when thunderstorms brought locally severe thunderstorms and heavy rain. The rest of the month was fairly tranquil with minimal precipitation and frequent dry days, making for pleasant late summer weather… a welcome extension to a summer that started off cool and wet. All in all, a pleasant end to the summer of 2008.
