Waterloo Region Rainfall Records: April 2026 Was the Wettest in 15 Years

April 2026 was the wettest April Waterloo Region has seen since 2011, with just over 130 millimetres of precipitation recorded at the E.D. Soulis Memorial weather station at the University of Waterloo. Most of that came early, with 100 mm falling in the first half of the month alone, making this the sixth wettest April on record and a month that combined heavy rain, late snow, and sharp temperature swings.

The month did not just bring rain. It also included 2 cm of snowfall, pushing the region's seasonal snowfall total to 241.5 cm, the third-highest on record for Waterloo Region. Temperatures were volatile too, ranging from a high of 22.1 C to a low of -7.6 C, a reminder that spring conditions in southwestern Ontario can still snap between thaw and frost.

That mix matters because it raises the risk of soggy lots, delayed outdoor work, and short-term strain on drainage in established neighbourhoods across Waterloo and Kitchener. With flood-prone properties already getting attention elsewhere in Ontario and late-season frost advisories appearing south of Waterloo Region, this was not just a wet month on paper. It was a month that tested how homes, yards, and infrastructure handle fast swings in weather.

For Kitchener's housing market, the timing is notable. Basara market data shows 811 active listings across neighbourhoods and average months of inventory at 1.6, which is still a relatively tight supply backdrop even with spring listings coming online. In other words, buyers have more choice than in a severe seller's market, but not enough to erase the pricing pressure on well-located homes.

That helps explain why some pockets are still holding value. In Columbia Forest and Clair Hills, freehold homes averaged $1,052,838, up 6.2 per cent year over year from $990,926, with homes taking 44 days to sell. Even after an unusually wet month that can expose drainage, grading, or foundation issues, buyers are still paying up in established west Kitchener neighbourhoods when the property checks out.

A record-wet April is the kind of local story that can influence buyer behaviour more than headline mortgage news. When inventory sits at 1.6 months and prices in areas like Columbia Forest and Clair Hills are still above $1 million, weather-related property condition becomes more important, not less, because buyers have enough choice to be selective without the market turning soft.
