Residents in Burlington are facing a chilly and overcast start to the weekend as cool, unsettled weather moves through the region this April 5, 2026. While the calendar marks the arrival of spring, current conditions feel more like late winter due to temperatures that are hovering below seasonal norms.
According to The Weather Network, Burlington reached an overcast high of 6°C today, but the wind and air conditions have kept the feels-like temperature between 1°C and 5°C throughout the day. Light rain brought about 0.4 mm of precipitation this morning, and officials expect the remainder of the day to stay mainly cloudy with a 30 to 40 percent chance of scattered showers.
The cold temperatures are partially driven by the chilly water in Lake Ontario, which currently sits at approximately 4°C to 5°C. This cold water helps moderate the air near the shoreline, contributing to the biting feel of the day. For those heading outdoors, experts advise dressing warmly, as tonight is expected to drop to a low of 0°C.
This stretch of cool weather is part of a broader pattern for Southern Ontario this spring. Meteorologists note that the region is experiencing the effects of a split polar vortex, which has allowed cold Arctic air to push into the area. While April is historically known as a volatile month for weather across the country, this year’s transition is proving to be particularly slow as winter’s chill persists against the seasonal warmup.
