What is the weather like in Mississauga?
Like all weather forecasts, there are no guarantees that each year will be the same, especially in Canada. Nevertheless, summers (late May, June, July, August) in Mississauga are generally hot (normally 25 to 32 degrees Celsius). By late September to early October, the temperature drops to 10 to 15 degrees or so, while the leaves change colours and fall off the trees. Winter weather varies from year to year; sometimes snow arrives as early as November; other times, significant snowfall may not occur until late December or early January. Regardless, the temperature tends to hover around 0 degrees Celsius (but it can rise up to 10 or 15, or fall to below -20 degrees, sometimes colder). This below-zero trend continues through February and early March, when signs of spring begin, as temperatures eventually climb to about 10 degrees. Late March and April are often pleasant with a mix of 1020 degree temperature and some rain.
