June 2009 Summary

A cold June with average precipitation

Even a streak of very hot days near the end couldn't prevent the month from being the coldest June since 2004. Overall, the daytime high temperatures were 1.5 degrees below average including 5 days that were colder than average by more than 5 degrees. It also got down to a frigid 2.9 °C on the morning of the 4th, this was the coldest June temperature since 1998.

A wet end to the month brought us back into the average range for precipitation after a dry start, the final total was 75.8 mm which isn’t too far below the average of 80.0 mm.

The total for the year so far is 485.2 mm compared to an average of 415.0 mm. Although we have had a lot of precipitation this year, it still only ranks as the 6th wettest year going back to 1971, so unless we kick up the pace it doesn't look like it will be an extreme year.
