I thought it was a little cold on Sunday (May 25) so I thought I would take a look at the daily data for a weather station near me using Environment Canada’s web service.

I picked  VANCOUVER HARBOUR CS which is in the harbour in Vancouver BC.

It turns out May 25 was the 6th coldest maximum temperature since 1958 (the start of the data) and the coldest since 1998.  It was also the 9th warmest minimum.

Remember, this is just one day’s data for 56 years. But there isn’t much of a CO2 signal is there? (Click graph for larger)
