Geography and climate

Kingston is located at 44°13′12″N 76°28′48″W (44.22, −76.48),[10] and is located in hardiness zone 5. Kingston has a moderate humid continental climate (Köppen climate classification Dfb), similar to that of the inland Mid-Atlantic States and the lower Great Lakes portion of theMidwestern United States. The region has warm, humid summers and cold winters. Extreme heat and cold usually occur for short periods. It is considered a temperate climate when compared with most of continental Canada. In the fall and winter, temperatures are moderated by the delayed cooling of the Great Lakes and conversely delayed warming occurs on spring days. The lakes moderating effects allow for a longer growing season than areas at similar latitudes in the continent’s interior. Both spring and fall are generally pleasantly mild, with cool nights. Annual precipitation ranges from 75-100 centimetres (30–40 in) and is well distributed throughout the year with a usual summer peak. The area usually receives less snow than most of Canada because of the shorter, milder winter.

The central part of the city is located between the Cataraqui River to the east and the Little Cataraqui Creek to the West, with outlying areas extending in both directions. The eastern part of the city is accessible by the La Salle Causeway on Highway 2.

Kingston has a picturesque waterfront. Major features include Flora MacDonald Confederation BasinPortsmouth Olympic HarbourCollins Bay,Wolfe IslandGarden Island, the Cataraqui River (including the Inner Harbour and, within that, Anglin Bay).

Notable annual waterfront events include the CORK sailing regatta, the Kingston Dragon Boat Festival, and the Thousand Islands Poker Run.
