Lake Muskoka Location

45.0319, -79.4475

45.03186, -79.44752 View on OpenStreetMap →

Lake Muskoka sits at 45.0319°N, 79.4475°W, on the coast of Ontario, Canada. The marker on the map shows the spot the readings on this page come from. It usually sits a short distance from the town centre, out on the open water itself, so the numbers stay tied to the coast rather than a generic point inland.

Coastlines bend, headlands focus the water, and the temperature can run noticeably differently between two beaches that look close together on a map. Comparing nearby locations is a quick way to see how local geography is shaping the readings.
