Expect a high of 24°C and a low of 12°C based on the live forecast above, with a 40% chance of showers mid-week. This month brings a mix of warm afternoons and cooler nights, so plan for layering and carry an umbrella.
What are the temperature and precipitation trends this month?
Daytime highs will range from 18°C to 26°C, while overnight lows dip to 10°C–14°C. Rainfall totals are near average at 60–80 mm, with the wettest period expected around the third week. The toronto weather forecast 30 days shows a gradual warming trend toward the end of the month, but a brief cool snap is possible mid-month.
How does this compare to seasonal norms?
This month’s average high of 22°C is 1°C above the 30-year normal, while precipitation is within 5 mm of typical values. The Canada weather hub notes that similar patterns have occurred in three of the last five years, driven by a persistent ridge over the Great Lakes.
Will there be any heat warnings this month?
Heat warnings are unlikely, as daytime highs are forecast to stay below 30°C. However, if a ridge strengthens, a brief advisory could be issued for the 20th–22nd. Check Weather Warning for updates.
How accurate is the 30-day forecast?
Monthly outlooks from Environment and Climate Change Canada have a reliability of about 60–70% for temperature trends and 50–60% for precipitation. The toronto weather 14 days and toronto weather 21 day forecast are more precise for planning.
What should I pack for a trip this month?
Pack light layers: a jacket for cool mornings (10°C–14°C) and short sleeves for afternoons (up to 26°C). A waterproof shell is useful for the 40% chance of rain. The toronto weather forecast 60 days suggests similar conditions next month.
