Mojave Desert receives more rain than B.C. in last 90 days

Tuesday, October 4th 2022, 4:46 pm - Several B.C. communities have already set all-time October records as a result of the ongoing abnormal warmth.

An extraordinary stretch of weather will continue across southern B.C. this week, with an extended period of warmth and dry conditions expected. The exceptional drought across the South Coast region, along with summer-like temperatures, will continue through the weekend at least. In fact, it’s been so dry recently that in comparison to somewhere like Las Vegas, Nev., located on the outer edge of the Mojave Desert, more rain has been recorded in the last three months than the mere 41 mm that Vancouver aiport picked up in 90 days. Fours days into the month of October and already several communities in B.C. have broken all-time October temperature records as well. For details, read on.

This week: Unusually dry, warm conditions continues with no relief in sight

Another upper-level ridge building over Western Canada will keep the province sunny and unseasonably warm through at least the first week of October.

In fact, four communities have broken all-time records. In some cases, monthly records have been broken by as much as 2°C, which is highly unusual, says Tyler Hamilton, a meteorologist at The Weather Network. There is no sign of rain in the next 10-12 days.


The new and previous October highs are as follows:

  • Victoria: Oct. 2, 25.3°C (25.0°C on Oct. 2, 1935)
  • Campbell River: Oct. 1, 26.3°C (24.2°C on Oct. 1, 1992)
  • Comox: Oct. 1, 23.0°C (22.9°C on Oct. 1, 1992)
  • Port Alberni: Oct. 2, 29.3°C (28.3°C on Oct. 8-11, 1916 and Oct. 12, 1902)

As well, several communities are looking at potentially setting a record number of 20-degree days in October so far.

Here's what the current records are:


  • Campbell River: Seven in 1987
  • Comox: Four in 1945, 1952 and 1987
  • Nanaimo: Thirteen in 1987
  • Victoria: Seven in 1952
  • Abbotsford: Fourteen in 1944

Drought-stricken B.C. remains locked under dry pattern

This pattern isn’t very conducive for precipitation, either, as drought-stricken B.C. remains locked under a dry and dominant ridge.

"To put the lack of rainfall into perspective, parts of the Mojave Desert have received more rainfall in the last 90 days than B.C.," adds Kelly Sonnenburg, another meteorologist at The Weather Network.

In almost three months, parts of the B.C. South Coast and Vancouver Island have received less than 20 mm of rain. The majority of the southern half of the province has received less than 40-60 per cent of its normal amount of precipitation for that time period.

For Vancouver airport, specifically, 41 mm of rain has been reported in total from July-September.

"In comparison to somewhere like Las Vegas, Nev., located on the outer edge of the Mojave Desert and known for its arid climate, the airport in the city has reported 45 mm of rain throughout the same three months," Sonnenburg says.

This extraordinary period of warm and dry weather is set to continue through at least the weekend ahead, with no active weather in sight, yet.

All eyes will be on the forecast ahead and if there will be a break in this dry pattern, especially as we head into B.C.'s rainy season with October through January being the provinces top four rainiest months climatologically speaking.
