Up to the minute weather reports
for all areas of this huge province...
Most foreigners see Ontario weather and Canada weather in general as being cold and blanketed in snow for much of the year. While it is true that a small portion of the province is subarctic in climate the bulk of the land enjoys 4 seasons a year and average temperatures vary considerably from north to south, region-to-region and even within a region.
Ontario is such a massive province it is actually comprised of 3 main climatic regions:
- Southwestern Ontario weather - has a humid continental climate with warm (sometimes very hot), humid summers and cold winters. Precipitation ranges from 75 – 100 cm (30 – 39 in) annually. Rainfall is pretty consistently light throughout the year except though the winter months when snow falls from December to April. Southern Ontario has one of the mildest climates in Canada because of the moderating effects of the Great Lakes and dare I say, some effects due to global warming.
- Central and Eastern Ontario weather - has a more severe humid continental climate with very hot summers and long cold winters. Precipitation is about equal to Southern Ontario‘s but with more snowfall.
- Northern Ontario weather - has a continental climate with long cold winters and short summers, snowfall can stay on the ground for over half the year but precipitation averages only 70 cm (28 in) annually because of moderating factors around Hudson Bay, James Bay and Lake Superior. The most northern parts of the province have a subarctic climate with severely cold winters and short cool to warm summers.
Trying to determine the best time to travel to Ontario really depends on where you travel and what you are expecting to do during your Ontario vacation. Obviously if you are looking to go boating or camping you would most likely be visiting in the summer months but if you are looking to go ice fishing or skiing you will be making a winter visit.
Any time of the year is really a great time to visit but as you travel further and further up north winter travel is generally not very popular. Another thing to consider especially as you travel into the wilderness areas are the insects. Mosquitoes and black flies are a real concern the further north you travel and visitors should definitely be prepared with repellants and lotions during “bug season” otherwise you will suffer severe bites.
