June 2010 Summary

A warm June that was the wettest in over 40 years

Apart from a 5 day cold stretch at the beginning of the month, the rest of June was pretty warm. Overall it was a full degree warmer than average, despite the fact that the highest temperature was only 28.3 °C, the lowest June high since 1993.

But the real story was the precipitation, at 130.3 mm it was the wettest June since 1967 and the wettest of any month since December 2008. The rain was consistent with a large storm (over 10 mm) occurring at least once a week and 17 days with some precipitation compared to 12 days on average.

But even with this really wet month the precipitation for the first half of the year is still a bit below average. We have had 372.3 mm so far in 2010 and the average at this point in the year is 415.0 mm.

Summary for June 2010:

Maximum Temperature 28.3 °C
Minimum Temperature 5.4 °C
Average Daily High Temperature 23.1 °C (Long term average 23.6 °C)
Average Daily Low Temperature 13.6 °C (Long term average 11.3 °C)
Total Precipitation 130.3 mm (Long term average 80.0 mm)

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

1 step forward, 2 steps back

The updates and rewiring weren't 100% successful, sorry but I am going to have to take off the pressure again until we figure out what is happening with it.

Isolated rain on Saturday

Looking at the precipitation report from the GRCA you can see that Cambridge was the only location in the area that got any rain this past Saturday. Crazy to see one location get almost 25 mm and Ayr getting 1 mm was the only other station that reported any.

Spring 2010 Summary

Warmest Spring since 1998 with average precipitation

It was a full 2 degrees above average this Spring, making it the warmest since 1998. The warmth was pretty consistent with only a week of colder temperatures in May and a few in June that were significantly below average.

Although we got around 25 mm more than the average precipitation for the season, this is still within the average range (albeit on the high side). It was also a feast or famine situation with the precipitation, as for most of it we would go a week or two without anything and then have a few very wet days in a row.

Summary for Spring 2010:
Maximum Temperature 31.3 °C
Minimum Temperature -7.1 °C
Average Daily High Temperature 17.9 °C (Long term average 15.9 °C)
Average Daily Low Temperature 6.2 °C (Long term average 4.4 °C)
Total Precipitation 243.5 mm (Long term average 219.5 mm)

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