This is an ideal time for enjoying the town's parks, such as Boardwalk Park along Windsor Lake, and exploring the local trails without the intense heat of summer. You'll find the foliage is lush and green, and there are often local markets and outdoor events beginning to pop up.Early autumn also offers comfortable temperatures, typically between 10°C and 20°C, and the landscape is often adorned with beautiful changing leaves, particularly around the many open spaces and reservoirs. This season is superb for couples looking for a picturesque getaway, perhaps enjoying a leisurely stroll around Windsor Lake or visiting local breweries and wineries. The crowds are also generally smaller than in the peak summer months, making for a more relaxed experience.While summer (July and August) is popular for water sports on Windsor Lake, it can be quite hot, with temperatures often exceeding 30°C, and can be busier.
