June 2011 Summary


Average temperatures for June and the first dry month of the year


Nothing too spectacular about the temperature in June, a few hot days at the beginning and a few cool days after that made for overall temperature that was just 0.3 degrees warmer than what we would expect putting it within the average range.

For the first time this year it was a drier than average month. Although it wasn’t drier by much as we had 60.4 mm and the average range starts at 64 mm. There was only one really wet day of the month, the 22nd when 28.2 mm fell, and there was a dry stretch from the 9th to the 20th.

Even with the relatively dry month, we still had 602.0 mm for the first half of the year which is well above the average of 415.0 mm. This is the second wettest first half of the year in the area since records began back in 1914. Only in 1947 was it wetter when 624.8 mm was recorded from January to June.

Summary for June 2011:
Maximum Temperature 32.0°C
Minimum Temperature 5.6°C
Average Daily High Temperature 23.2°C (Long term average 23.6°C)
Average Daily Low Temperature 12.2°C (Long term average 11.3°C)
Total Precipitation 60.4 mm (Long term average 80.0 mm)

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

So in June we got less rain than average. That's about what I expected to read in your report. We got about 75% of the normal amount of rain, and of that, about half fell in one day. Ha Ha Ha.

Is your thermometer broken? Why such a big temp difference between environment canada weather station and yours?

Wow, that must have been the hottest temperature ever recorded in the area dating back to 1970 at least.

Yes our high temperatures have been a bit higher than others in the area, we are investigating the reason.

Haha, high to say the least... The calibration of the thermometer is clearly wrong. 3 days in a row of 37C? Humidex of 52? Are you leaving it out in the sun?

Just leave it as is for Thursday. I want to see a 45C and 60 Humidex reading.

It seems unlikely the thermometer itself is the problem. It's reading fine outside of the mid-afternoon hours. Maybe the Stevenson screen, or some changes to the landscape nearby?

A problem with the shield is a possibility, we are looking into it.

Any chance the screen has just got dusty (and therefore darker)?
