https://www.accuweather.com/en/ca/vancouver/v6c/june-weather/53286 Well, it looks like Vancouver, BC will have had 20 June days above 20C. Only 10 of those days were over 25C and there were only 2 days that were at least 30C of 86F. That's hardly a June heatwave, but perhaps it is when compared to Alaska and Siberia.
