# "Its going to be another hot, dry summer"May 30, 2006 2:25 PM   Subscribe

How can I find out how many days around 30 degrees celcius there are going to be this summer in Ontario Canada?

I can find forecasts saying the temperatures are going to be higher than average but I need more specific. I can find data that tells me that there were x # of days above 25 degrees, but the data is averaged over the last 30 years which is no good.

Will this help? It will let you select a data interval, so it won't just be an average.

Oh, and you will want to toggle the menus from the bottom-up (the interval, and then the year), but then you could count month by month.

You'll pardon, but I'm afraid I'm not being facetious with this answer: The only way to find out is to go there for the summer and count them. By the end of September you'll know.

Weather forecasting isn't an exact art, and in any given year the number can fluctuate quite a lot compared to the historical record. I think the reason you can't find an answer is that no one knows what the answer is.

In fact, there's reason to believe that accurate predictions that far into the future are impossible. An entire new mathematical field has been built around that discovery.

Oh, sorry, you meant for this coming summer? Nevermind. Steven CDB is correct.

Well, according to that Environment Canada resource, Im going to need an air conditioner...

It's 33 celcius (here in Toronto) TODAY. It's not even June yet. It was 33 yesterday too. And it's going to be hot for another day before it drops off to 10-20 on Thursday for a week. You just never know.

I'm guessing it's going to be at least 30, every single day, from middle of june until the end of August. Any cooler days would be the exception to the rule.

I think you'll find it easier to find data that doesn't account for humidex, but it is/was a Canadian invention so... My best answer is the University of Waterloo Weather Station. They put out all kinds of obscure statistics and Waterloo is pretty central so that might be helpful. If you ask nicely they might even do some kind of custom query on their db for you.
