WEDDING - OCTOBER 19, 2019 - BRAMPTON, ON
Our Wedding Date is October 19th of this year in Brampton, Ontario. What is the prediction for the weather on that day, as well as the week leading up to the 19th? I know where I am planning to have pictures will not work if it is raining, or just after a rainfall. I have other places to go have pictures taken, but I am really hoping to have pictures at the outdoor location.

Parasol Weather
Hi, Teresa and Edwin: We show a few showers and slightly cooler (not a bad thing) that week, but on and off, nothing to worry about. We hope your mom has a nice party–she sure has nice kids! Have a parasol ready to shade her from showers OR sun! And thanks for asking!
