Autumn (September – November): Autumn in Barrie is a picturesque season, showcasing a stunning display of fall foliage. Temperatures gradually cool down, with average daytime highs decreasing from the low 20s°C (70s°F) in September to around 5°C to 10°C (40s°F to 50s°F) by November. Evenings become noticeably cooler, requiring warmer clothing. Rainfall is still frequent, and the first snowfall usually occurs in late October or early November. The variability of temperatures during this period makes layering clothing a practical choice.

Winter (December – February): Winter in Barrie is characterized by cold temperatures, heavy snowfall, and blustery winds. Average daytime temperatures hover around -5°C to -10°C (23°F to 14°F), but can dip significantly lower during cold snaps, sometimes reaching -20°C to -30°C (-4°F to -22°F) with wind chill. Snowfall is abundant, with Barrie receiving an average of over 200 cm (almost 80 inches) of snow each winter.

However, spring can be unpredictable, with periods of warm sunshine interspersed with cool, rainy days. The melting snowpack often leads to muddy conditions and potential flooding in low-lying areas. The later part of spring sees the emergence of greenery and the return of migratory birds.

Overall, Barrie’s weather provides a diverse experience throughout the year.
