August 2009 Summary

An average August for both temperature and precipitation

Cold. Hot. Cold. That pretty much sums up August as far as the temperature was concerned. Eight colder than average days, then thirteen warmer than average ones, followed by 10 more cold ones. And as often happens in this situation, the cold days were offset by the warm ones and we ended up with an average overall temperature for the month.

Going in the last weekend of the month it looked like we were going to end up below average, but nothing like over 25 mm on a single day to bring us back into the average range. But don’t forget about those 10 hot days in the middle of August when there were only a few millimetres of rain.

The total precipitation for the year so far at 649.1 mm is edging just a little closer to the average of 596.0 mm.


Summary for August 2009:
Maximum Temperature 29.9 °C
Minimum Temperature 6.5 °C
Average Daily High Temperature 24.3 °C (Long term average 24.7 °C)
Average Daily Low Temperature 14.0 °C (Long term average 12.6 °C)
Total Precipitation 81.1 mm (Long term average 87.0 mm)

(Long term averages based on 1971-2000 data for the Waterloo Wellington Airport)
