Burlington, Ontario, is bracing for a week of unsettled weather, with Environment Canada forecasting rain and a risk of thunderstorms through Thursday. As of Monday afternoon, conditions were mild at 18°C under partly cloudy skies, but that calm is not expected to last. No weather alerts are in effect, but residents should keep umbrellas close as storm chances climb.

Tuesday will bring a mix of sun and cloud, with a 40 per cent chance of showers and a risk of thunderstorms in the afternoon. Temperatures are expected to reach 22°C, but it will feel more like 25°C with the humidex. Winds from the southwest will gust up to 50 km/h. Overnight, the chance of showers or thunderstorms rises to 60 per cent, with 1 to 3 mm of rain possible.

The highest risk of stormy weather arrives Thursday, when there is a 90 per cent chance of morning showers and a risk of thunderstorms. It will be the warmest day of the week, with a high of 24°C, but also windy. Residents can expect periods of rain to continue off and on through the week, alternating with sunny breaks.

The wet weather also impacts local beaches. Brant Street Beach already failed provincial water quality standards as of June 10, and the upcoming rainfall makes conditions worse. Halton Region Public Health warns that rain washes bacteria like E. coli into Lake Ontario. The health department advises against swimming for at least 24 to 48 hours after heavy rain, so the beach is unlikely to be safe for swimming this week.

Burlington’s weather is monitored at the Burlington Lift Bridge station by Environment Canada, while The Weather Network provides additional forecast details. Residents can stay updated through their local forecasts and plan outdoor activities around the storm risks.
