Welcome to the QUEBEC CITY TRAVEL FORUM.
Well May is still Spring… June is beginning to feel a lot more like Summer (remember we told you, we kick off Summer as of Victoria Day Weekend late May). May is an ok time to visit, June is better, and July & August are always best weatherwise.
The QUEBEC TRAVEL PAGES – and the TRAVEL GUIDE says that the averages for that time of year are Highs of 60 F and Lows of 42 F… I also took a look at the Government of Canada’s Official Weather Office info at Environment Canada, and here are their statistics for May Averages…
Average Daily Temperature = 11.2 C (52 F)
Average Daily Maximum Temperature = 17.1 C (63 F)
Average Daily Minimum Temperature = 5.3 C (42 F)
Extreme Maximum Temperature = 33 C (91 F) = May 29, 1978
Extreme Minimum Temperature = -7.8 C (18 F) = May 8, 1947
Environment Canada – Quebec City Airport Weather Averages = …weatheroffice.gc.ca/climate_normals/…
Environment Canada – Quebec City Airport Weather Averages = tinyurl.com/EnvCan-QCityAirportAverages (foreshortened because sometimes TA won’t support lengthy Website Addresses)
The link the Environment Canada Website will give you data for every month of the year, so you can easily see why we consider June (Daily Average = 16.5 C), July (Daily Average = 19.2 C) & August (Daily Average = 17.9 C) to be better picks.
Hope this is helpful,
