Southern Ontario's Niagara Region lies between two Great Lakes - Erie to the South and Ontario to the North - and is considered to be a moderate climate zone. Because the two bodies of water moderate the area's temperatures, the Niagara Region is ideal for tender fruit growing. Also, its long warm-weather season makes it near perfect for such outdoor activities as golf, cycling and boating.
By mid-April, the region can enjoy temperatures well over 12°C (50°F), with temperatures warming up rapidly by mid-May. The long, warm summer can continue well into September.
Mid-summer is punctuated by mild fluctuations of temperatures with short periods of humid days that can reach into the 30's°C (90's°F). But the average mid-summer temperature is usually in the high 20's°C (80's°F). Autumn, when harvests are in full swing, sets in gradually and is often considered to be the most enjoyable season of the year in Niagara.
The sun shines in The Peninsula between 1,800 and 2,000 hours annually, with December being the greyest month. But the bright sunshine of the growing season more than makes up for the dull days.
Uniform precipitation is expected throughout the year, with no remarkable periods of wet or dry peaks. Winter snowfall is usually minimal, with the odd snowstorm setting in and temperatures rarely reach below 0°C (-32°F), another important factor for the fruit-growing belt. Forty inches or less of snowfall is standard in The Peninsula. With milder winter temperatures, precipitation can turn to rain even in December and January.
