October 2009

It's been a very wet month... 235.7mm of rain has fallen in Sydney Mines so far, and the month isn't even over!

We've broken the record for the most snow ever in October, and we're on track for the coldest October on record, certainly for daytime highs (little chance of recovery during the week ahead). Precipitation amounts have exceeded 190 mm, which I believe places in the top 3 wettest of all time.

How many days-with-snow does Gander have so far this October? Wonder what the record is? Will be an interesting stat to see come Saturday.

7 days so far, the record is 11 (1985).

October 2009 featured an abundance of gloomy weather around here. :ph43r:

The monthly mean temperature came in just a tenth of a degree above the record for the coldest October ever (which was 3.8°C in 1984 & 1986). However the average daily maximum temperature is the coldest on record, almost a full degree colder than the previous record (which was 7.4°C in 1984 & 1986).

The monthly precipitation total was the second highest on record (the highest being 220.0 mm in 2003). The snowfall total destroyed the old record (42.4 cm in 1940). We also set a record for the most days of measurable precipitation and most days of measurable rainfall. We were one day short of setting a record for the most days of measurable snowfall.
