When is the best time to visit Newmarket?
Late May to June and September to early October offer mild temperatures and less humidity. July and August are warm but can be muggy. January and February are coldest, with regular snow.
Does Newmarket get lake-effect snow?
Yes. Newmarket can receive lake-effect snow from Georgian Bay and Lake Huron, especially when northwest winds blow. This can add to the average 130 cm of annual snowfall and cause sudden accumulations.
How reliable are the 7-day and 14-day forecasts for Newmarket?
A newmarket weather 7 day forecast is fairly reliable for trends, but day-by-day accuracy drops after day 5. A newmarket weather 14 day forecast is best used for general patterns, not specific temperatures.
