‘Temperatures will be dropping:’ Nanaimo to see break from summer heat

Jun 23, 2026 | 4:55 PM

NANAIMO — It might only be a little bit of rain, but every drop will help stave off drought concerns.

Following weeks of warm, dry, sunny weather across much of Vancouver Island, a strong high-pressure system is poised to break down and move off beginning Thursday, June 25, leaving a pathway for some long-overdue rainfall.

Environment Canada meteorologist Jennifer Cowal said areas of the south and west coast of the Island, along with the Sunshine Coast, will see most of the rainfall.

“We’ve got a low-pressure system that’s approaching from the Pacific, it’s going to be a real change in pattern to what we’ve had for the last weeks. Temperatures will be dropping, we’ll have increasing cloudiness, and then we’ll have rain starting Thursday into Friday morning.”

While parts of eastern Vancouver Island, including Nanaimo and Oceanside, will likely only see around five millimetres of rain, other parts could see upwards of 25 millimetres.

Far from a record-breaker in late June, Cowal said every little bit helps.

The rainfall will, at least temporarily, help the wildfire situation across the region, following a number of small sparks in recent weeks across parts of Vancouver Island.

Cowal said the very strong high-pressure system, which had been in place for the last seven to 10 days, prevented any storms from coming through.

“There’s been a very persistent ridge of high pressure over the south coast, and you can imagine it as a block of warm air, it’s stagnant, it’s in place, and when there’s a system that comes towards it, if the high is strong enough, it will just deflect any weather system around it.”

Cowal added another high-pressure system is developing in the Pacific at the moment but will run into some more unsettled weather from northern Canada and Alaska in the next week, with a wait-and-see approach on how much active weather the Island will see.

Temperatures are forecast to be well above normal for much of the summer months locally.

Stage three water restrictions are already in place in Nanaimo and Parksville, as well as many parts of the Regional District.
