What is the warmest Ottawa gets in the summer?

And what is the coldest temperature it gets in the winter?

(I'm asking for average temps, not like warmest/coldest on record)

"Summer:
Ottawa summers can be very hot and very humid. Temperatures can start at 20 degrees Celsius and go as high as 42 degrees Celsius. The hottest months are July and August. If you are coming at that time of year make sure to bring light clothing, a hat and a lot of sunscreen!"

"Winter:
We can try to sum it up by saying that it is cold and snowy but that wouldn't explain it properly. We like to describe it as unpredictable because it is hard to say what a "normal winter" is. It changes from one year to the next. One year it will begin to snow in November and the next year it may not snow until late December. As for the temperature, one January day can be -40 degrees Celsius with the wind but a few days later it can rise to +5 degrees Celsius.

So, your best bet is (if you are visiting in the wintertime) make sure to bring layers of clothing so you are prepared for any type of winter. Don't forget your hat, mitts/gloves, scarf, jacket & boots!"
