Warm and dry conditions expected in Ontario due to forming “Rex block”
Published May 25, 2023 at 11:38 am
Don’t let the charming image fool you; the weather pattern in the forecast for most of Ontario won’t actually take the shape of everyone’s favourite dinosaur–but it does share the well-known name!
Environment and Climate Change Canada (ECCC) recently tweeted that an extended period of “warm and dry conditions” is in the forecast for most of the province (with the exception of northwestern Ontario, where some rain is expected) due to a “developing Rex block.”

What is a Rex block, you might ask?
According to the ECCC, it actually has nothing to do with super cool prehistoric beasts.
“It’s an atmospheric blocking pattern where high pressure situated north of low pressure prevents the progression of weather systems,” the environment agency said in a tweet.
“It is also named after its discoverer, and does not have anything to do with dinosaurs.”
As for what kind of temperatures to expect, the ECCC is calling for more summery days between now and May 31, with temperatures in Mississauga, Brampton and Halton expected to range from 21 degrees tomorrow (May 26) to 28 degrees by the middle of next week.
Days will be slightly cooler in the Hamilton and Niagara regions, with temperatures topping out at 24 to 25 degrees next week.
Parts of Durham, including Oshawa, will see slightly higher temperatures, with a high of 29 in the forecast for May 31.insauga's Editorial Standards and Policies advertising
