Weather Talk: July-August time frame has lowest average wind speedsThere is no doubt that we live in an area that is prone to a persistent wind. The wind plays a strong role in our climate due to our flat terrain in combination with our geographic location in the middle latitudes where air mass exchanges are routine.
The windiest periods of the year on average are in the autumn and spring, when warm tropical air and cool Canadian air often clash in this region, developing storms with strong pressure gradients that create the higher wind speeds fairly common during those seasons.
The time frame with the lowest average wind speed is in July and August, particularly from the middle of July to the middle of August. This time of year the temperature contrast from the equator to polar areas is the lowest of the year; this induces weaker storms to form and, in turn, fewer wind events. It does not mean every day will be calm, but the days with gusts over 30 mph tend to be few. Yet, it won’t be too long before those autumn cold fronts will be whipping up the wind once again.
