Burlington, Ontario is in for a classic changeable summer week, with hot and humid conditions early on giving way to a sunny stretch before rain chances return for the weekend, according to Environment Canada.
Monday starts the week under a mix of sun and cloud with a high of 25°C and a humidex making it feel more like 33. Winds from the northeast will blow at 20 km/h, and the UV index is expected to hit 8, which is considered very high. Residents heading out should take sun protection seriously.
The muggy conditions ease only slightly on Tuesday. Tuesday starts mainly cloudy before clearing in the afternoon, and temperatures climb toward 30°C by Wednesday under full sun. Highs will dip slightly as the week goes on, with 29°C on Thursday and 27°C on Friday.
The stretch of mostly dry weather breaks late in the week when a 30 percent chance of showers moves in for both Thursday and Friday. Thursday will see a mix of sun and cloud with that slight risk, while Friday is expected to be cloudy with the same low shower chance.
Saturday should see a return to sunny conditions with a pleasant high near 28°C, offering a solid finish to the week for anyone with outdoor plans.
Lake Ontario remains cool for this time of year. Water temperature near Burlington is currently 18.9°C, just below the typical 20°C threshold that usually marks the start of swimming season in July. Beachgoers can expect the lake to warm into more comfortable territory as the month progresses.
