Rainfall in July significantly more than normal

Kamloops received an above average amount of rain in July, but it was a return to normal compared to a drier month in 2017.

A total of 39.9 millimetres of rain fell on the Tournament Capital last month, with 22 mm falling over the course of a sopping wet Canada Day long weekend.

“Average rainfall is 31.4 mm, putting it at 127 per cent of normal,” said Environment Canada meteorologist Lisa Erven.

By comparison, in July of 2017 just 3.4 millimetres of rain fell in Kamloops.

“We were substantially drier,” she said.

This past July is by no means a record, however, as the wettest day on record for Kamloops is 42.2 mm of rain recorded on July 1, 1954.

In the entire month of July 2018, 43.6 mm of rain fell on Kamloops and there was about

7 mm that fell in July 2015.

May to September are the wettest months for Kamloops.

Erven said she is not surprised to see those numbers fluctuate as they have in the past three years because it’s difficult to measure rainfall amounts throughout thunderstorm season given the fact many can be small.

Erven said July started off cool and wet across the province, but by mid July there were ridges of high pressure that caused a pair of heat waves from July 12 to July 19 followed by cooler temperatures and showers before the mercury bounced back into the 30s by the end of the month.

Kamloops saw record heat and dry conditions in May, recording its warmest and fourth-driest May on record, which was followed by an average June that saw temperatures closer to the average 18C and 36.8 mm of rain compared to the normally expected 37.4 mm.
