Environment Canada record keeping sucks YUGE donkey nuts. You'd think that in this day and age where computers can pick up records a lot easier than humans they'd be getting better not worse.
So, I clicked on Kelowna normals
, and it says that the all time record low for the month of June (set in 1973 at -0.6C), BUT if you look at June 2002
, the temperature was -1.3C then.
You might be thinking, "Aw, but the hourly temperature was only 0.0C in June 2002," but that's only because you don't know the Kelowna airport. It's an amazing frost hollow spot that can easily drop several degrees between hours and then rise again before the next hour. It happens frequently, and in fact, the -0.6 (31F) record from 1973 only had an hourly reading of +0.6 (33F). Oh, and the temperature passed "quality control", so it's not like they are suspicious of the number.
EC just sucks sometimes. That said, I will give them credit for putting all the data online. Most meteorological agencies aren't so generous about that.
