Summer solstice on Wednesday

Staff writers
June 18, 2012 — Despite the warm temperatures many Canadians have experienced, it's not actually summer yet -- but it will be officially on Wednesday, June 20.

Wednesday, June 20, is the summer solstice, which marks the beginning of astronomical summer.

It's the longest day of the year in the northern hemisphere and the shortest in the southern hemisphere. 

In southern Ontario, the sun will be above the horizon for almost 15.5 hours.

Above the arctic circle, 66.5 degrees north, the sun will not set at all.

Of course, that means the number of daylight hours will begin to shrink after Wednesday. Day and night will be more or less equal length on September 22, the autumnal equinox.
