Well, the weather here is often variable, as I occasionally write about it.

Here is another example:

On May 21, there was wet snow in Dundalk, an hour north of here. Some people had to scrape their windshields as if it is January.

On May 22, on Victoria Day, it was +5C with really chilly wind as if it is October or November. I had to wear a winter coat on that  day.

On May 29 and 30, it was +33C and extremely hot and humid.

On May 31, severe thunderstorms caused flooding in parts of Waterloo (knee deep water), as well as lightening that struck several areas causing power outages and even a few fires.
