outdoor wedding

I am getting married July 20 and it is being held outside, can you advise what kind of weather I could expect for that day.

July Forecast

This is a reply to Ellen. The July 20-21 weekend will most likely be very warm. A good chance it'll be 30 C. It is typically the warmest time of the year right around that time and the nights are very warm too. As for rain, id know better a month or two away but there's a good chance of a thunderstorm sometime that week. July will most likely be above normal as a whole.

Outdoor Wedding

Any changes in your forcast for July 20?

June 28/29/30 - prediction for outdoor wedding

We are holding an outdoor wedding in Bradford Ontario on the June 28-30 weekend. Any predictions on the weather for then? It seems it will be during a heat spell...

Late June Forecast

This is a reply to Brooke. The last few days of June will most likely be very warm. A good chance it'll be around 30 C. June is predicted to be below normal but it'll most likely start to get very warm the last few days and carry over into most of July. It'll most likely rain a bit over that weekend but most of the weekend will be sunny. I'd know better in a good month from now
