Kingston Ontario – Sailing Conditions for July

Airport Data for 1985-1998, courtesy of Environment Canada

Kingston is fortunate to have a thermal wind that arises most afternoons and usually reaches 10-12 knots. This wind is attributed to the topography of the area and specifically the presence of lakes and the rocks of the Canadian Shield to the northeast of the city.

Kingston airport is close to the water, approximately 1 mile from the sailing site, and keeps weather records. As shown on the wind roses compiled there, comparison of the 12 and 14 hour polar charts shows clearly the swing of the wind through to the Southwest as the thermal wind starts up for the afternoons during the month of July.

The histogram plot shows the wind speeds through the day. Thus it is seen that the wind is over 6 knots at 10 AM no less than 65% of the days, and from noon to 1600 hours it holds above 6 knots over 85% of the days.
