Waterloo Region saw the driest June in 15 years.

According to the University of Waterloo weather station, June had total precipitation of 48.6 mm — the driest since 2007.

Compare that with the long-term average precipitation for the month, which is 82.4 mm.

About half of all of June's precipitation fell in the first week.

Then, there was two weeks of next to no rain.

Frank Seglenieks, the UW weather station coordinator said this isn't surprising.

So far this year, there's only been one month of above average precipitation, which was February.

The first half of 2022 only had 323.2 mm of total precipitation, which is well below the average total of 416.1 mm.

June also saw average temperatures, with very warm days and cooler nights.

There were six days above 30 degrees, while the average is only two days.

Daily high values were 1.3 degrees above average, but daily lows were very much below average by 2.3 degrees.

This rounded things off for the month so that temperature was half a degree below average, which still keeps June in the average range.

The maximum temperature in the month was 34.1 degrees, which was the high on June 21.

This was the highest temperature since 34.5 degrees on July 9, 2020, as well as the highest June temperature since June 27, 2005, when it was 34.9 degrees.

The minimum temperature in June was 3.8 degrees.

During the month, the average daily high was 24.9 degrees, which is higher than the long-term average of 23.6 degrees.

But, the average daily low was 9.2 degrees, which is below the long-term average of 11.5 degrees.

The UW weather station is also currently in the process of setting up a replacement main controller, after the original one stopped working at the end of January.

As a result, the data for this month, instead, comes from readings taken at the Waterloo regional airport.
