Aurora, Ontario, is in for a stretch of mild autumn weather this week, with daytime highs ranging from 15 to 20 degrees Celsius and overnight lows between 4 and 11 degrees, according to Environment Canada. No weather alerts are in effect for the area.

The forecast issued Monday, September 21, calls for a mix of sun and cloud through Thursday, with a high of 15 degrees on Monday, rising to 19 degrees by Wednesday. Friday is expected to be sunny with a high near 20 degrees. Overnight temperatures will dip to around 4 to 11 degrees, typical for this time of year.

These conditions match the seasonal normals for late September in Aurora, which see a maximum of 18 degrees and a minimum of 8 degrees. The week also marks the astronomical start of autumn, with the fall equinox occurring around September 22.

Residents can take advantage of the pleasant weather for outdoor activities, especially as the town’s outdoor sports field season runs until September 30, meaning late September is one of the last stretches for organized play before weather-dependent bookings kick in.

Observations are being recorded at Environment Canada’s King City North weather station in nearby King City. Forecasters note that a strong El Niño pattern is contributing to warmer-than-average temperatures across Ontario this fall.
