April in Ottawa was significantly wetter than average, with total rainfall exceeding 100 mm, according to meteorological data. The month saw frequent rain events and heavy fog, as captured in a photograph of downtown Ottawa on April 16, 2026, by Sean Kilpatrick of The Canadian Press.
Weather Patterns
The increased precipitation was part of a broader weather pattern affecting the region. Residents experienced multiple days of rain, with some periods of dense fog reducing visibility. The wet conditions were above the historical average for April, which typically records around 70 mm of rain.
Impact on Daily Life
The heavy rain and fog impacted daily activities, including commuting and outdoor events. Drivers were advised to exercise caution on roads due to reduced visibility and slippery conditions. The fog was particularly dense in the downtown core, creating challenges for pedestrians and cyclists.
Despite the wet start to spring, temperatures remained mild, with highs in the low teens Celsius. The combination of rain and cool temperatures delayed some outdoor construction projects and gardening activities.
Meteorologists attribute the above-average rainfall to a persistent low-pressure system that stalled over the region, drawing moisture from the Great Lakes. This system is expected to move eastward, bringing drier conditions in the coming week.
Residents are advised to stay updated on weather forecasts as May begins with sunshine and warmer temperatures, offering a reprieve from the April showers.
