I am not doing the Celsius conversions on all these temps but the weather forecasters is 30C (86F) as a milestone in our forecasts. We average 13 days a year over 30, we are at 18 already and are forecast for about 8 in a row coming up. So dry even inside the city there is a fire ban, can't even use charcoal grills, nothing but gas.
There is a river an hour east of us that is very popular with the white water ground, I can't remember what it is normally categorized but we were out there on July 1st and it was so low I could see the silty bottom. Normally nothing but foam in certain spots. Often have a line of people waiting to launch but not a one on the holiday.
