September is the best month to visit Toronto: 21.9°C / 71°F daytime highs, 14.5°C / 58°F at night, and only 36.6mm (1.4 in) of rain spread over 7 days. June runs a close second at 24.7°C / 76°F with 10 rainy days, and August is the driest-feeling month of the year with rain on just 6 days. Avoid May, which took 160.3mm (6.3 in) over 15 days — the wettest month by a wide margin and half the month soggy.

The best months: September, June, and August

September is the one to book. Highs of 21.9°C / 71°F are the temperature where you can walk from Kensington Market to the Distillery District without either sweating through your shirt or needing a real coat. Lows of 14.5°C / 58°F mean patio dinners work with a light layer over your arms — not a jacket, a long-sleeve. The rain figure is what makes September win outright: 36.6mm over 7 days averages about 5mm per wet day, which is drizzle-and-move-on weather, not a washout. You will lose part of an afternoon, not a day.

June gives you the warmest comfortable weather of the year: 24.7°C / 76°F highs and 16.1°C / 61°F lows, with 62.2mm (2.4 in) over 10 days. That's roughly 6mm per rainy day across a third of the month — enough that you should have a packable shell in your daybag, not enough to reroute a trip. June is also the longest-daylight month, so a 24.7°C evening at 8pm is still perfectly warm on the Harbourfront.

August is the sleeper pick. It has almost exactly June's temperature (24.8°C / 77°F high, 17.6°C / 64°F low) but rain on only 6 days — the fewest of any month. The catch is that August packed 71.6mm (2.8 in) into those 6 days, about 12mm each. That's the classic late-summer pattern: five perfect days, then a hard afternoon thunderstorm that empties the streets for an hour and leaves the evening cooler and cleaner. Plan around the storms rather than the calendar and August is excellent.

The months to avoid: May, then deep winter

May is the worst month to visit Toronto, and it surprises people because the temperature looks pleasant. Highs of 16.4°C / 62°F and lows of 8.7°C / 48°F are fine. The problem is 160.3mm (6.3 in) of rain over 15 days — more than double June's total, spread over half the month, averaging nearly 11mm per rainy day. That is genuine, sustained rain, not passing showers. On a five-day May trip you should expect two or three wet days, and at 16°C rain is cold rain: you will want a real waterproof layer and a second pair of shoes, and you will be spending more time in the ROM and the AGO than you planned.

January and February are the coldest months and effectively identical: January highs of -2.6°C / 27°F with lows of -8.2°C / 17°F, February highs of -2.3°C / 28°F with lows of -8.5°C / 17°F. Note that the daily high is below freezing in both. That's not "chilly" — it means water stays frozen all day, sidewalks stay icy, and any outdoor plan has a hard time limit of about 20 minutes before you need to go inside. January is genuinely the driest month on record (26.8mm / 1.1 in over 9 days) but that number is misleading in a useful way: at -8°C that precipitation arrives frozen, so low millimetres do not mean clear pavement.

February is worse than January despite the near-identical temperature, because it takes 77.7mm (3.1 in) over 12 days at the same sub-freezing highs. Cold plus wet is the combination that ruins trips.

December sits in the same bracket: 0.4°C / 33°F highs, -6.9°C / 20°F lows, and 89.2mm (3.5 in) over 12 days. A daytime high hovering right at freezing with heavy precipitation is the sloppiest possible mix — slush, not powder. Come in December only if you are here for Christmas markets and holiday lights, and come with waterproof boots rather than fashion boots.

Shoulder season: October, April, and November

October is the strongest shoulder month and the best value in the calendar. Highs of 15.5°C / 60°F and lows of 8.2°C / 47°F are jacket weather, not coat weather, and the fall colour in the ravine system and High Park is the real draw. The cost is rain: 76.1mm (3.0 in) over 12 days, so nearly 40% of October days see some rain. Roughly 6mm per wet day means showers rather than deluges, but October is the month where a hood earns its keep.

April is the underrated one. It is the driest spring month by a clear margin — 61.7mm (2.4 in) over 8 days, against May's 160.3mm over 15 — and highs of 11.2°C / 52°F with lows of 2.3°C / 36°F. It's cool, and those near-freezing nights are real, but April genuinely gives you more usable dry daylight than May does. If you're choosing between an April and a May trip on price, take April.

November is cheap for a reason but not a disaster: 6.8°C / 44°F highs, 1.0°C / 34°F lows, and only 39.5mm (1.6 in) over 9 days — the second-driest month of the year. It is cold enough that you need a proper coat and short enough on daylight that you'll be indoors by 6pm, but you are unlikely to be rained on much. For museum-and-restaurant trips where the weather is background rather than the point, November is defensible.

What each season actually means on the ground

Summer (June–August, 24.7–28.2°C / 76–83°F): You are outside most of the day. Waterfront ferry to the Toronto Islands, patio lunches, Blue Jays games, street festivals. Shorts and t-shirts by day; the 16–20°C / 61–68°F overnight lows mean you want one light layer for evenings on the lake, where the wind is real. Sunscreen and a refillable bottle matter more than a raincoat, except in July.

July specifically: 28.2°C / 83°F is the year's peak, with lows staying at 19.8°C / 68°F — the nights don't cool off, which is what makes a top-floor Airbnb without air conditioning miserable. Confirm AC before you book. July's rain pattern is the most misread number on this page: 35.5mm over 12 days is under 3mm per rainy day. Rain on 12 days sounds terrible; 3mm per day means brief afternoon storms that pass in under an hour. July is wet on the calendar and dry in practice.

Autumn (September–November, 21.9 → 6.8°C / 71 → 44°F): The 15-degree slide across three months is the steepest in the year, so the month you pick matters more here than anywhere else. September is still summer clothing with a sweater. October is a proper jacket and closed shoes. November is a winter coat with a scarf. Walking neighbourhoods and ravine trails are the point of an autumn trip.

Winter (December–February, highs 0.4 to -2.6°C / 33 to 27°F): This is an indoor trip with outdoor punctuation. Insulated waterproof boots, a coat rated for wind, gloves, and a hat are not optional at -8°C / 17°F lows. Toronto's PATH network lets you cross much of downtown underground, which is genuinely the reason a February trip works at all. Skating at Nathan Phillips Square, galleries, and food are what you're here for.

Spring (March–May, 5.7 → 16.4°C / 42 → 62°F): The most unreliable season. March still has lows of -2.6°C / 27°F against 5.7°C / 42°F highs and 80.0mm (3.1 in) over 10 days, so it's the tail of winter, not the start of spring. April is the sweet spot. May is warm and wet.

Month-by-month

• January — Coldest month. -2.6°C / 27°F high, -8.2°C / 17°F low. Driest on record at 26.8mm over 9 days, but frozen. Indoor trip only.
• February — Same cold as January (-2.3°C / 28°F, -8.5°C / 17°F) but three times the precipitation: 77.7mm over 12 days. The worst combination.
• March — 5.7°C / 42°F highs but lows still at -2.6°C / 27°F, plus 80.0mm over 10 days. Winter clothing, spring expectations. Skip.
• April — 11.2°C / 52°F, 2.3°C / 36°F lows, and only 61.7mm over 8 days. The driest spring month and the best cheap-trip window.
• May — Avoid. 160.3mm over 15 days at 16.4°C / 62°F. Warm enough to tease you, wet enough to ruin half the itinerary.
• June — 24.7°C / 76°F, 16.1°C / 61°F lows, 62.2mm over 10 days. Longest days of the year and reliably warm. Excellent.
• July — Hottest at 28.2°C / 83°F with 19.8°C / 68°F nights. 12 rainy days but only 35.5mm total — short storms, not washouts. Book air conditioning.
• August — 24.8°C / 77°F with rain on just 6 days (71.6mm). Fewest wet days of the year, but each one is a real thunderstorm.
• September — The best month. 21.9°C / 71°F, 14.5°C / 58°F lows, 36.6mm over 7 light days.
• October — 15.5°C / 60°F and fall colour, at the cost of 76.1mm over 12 days. Bring a hood.
• November — 6.8°C / 44°F highs, 1.0°C / 34°F lows, but only 39.5mm over 9 days. Cold and dry; cheap.
• December — 0.4°C / 33°F highs with 89.2mm over 12 days. Slush season. Holiday atmosphere is the only reason to come.

FAQ

What is the cheapest time to visit Toronto with decent weather?

Late April. Highs reach 11.2°C / 52°F, rain totals only 61.7mm (2.4 in) over 8 days, and it sits before the summer price jump. You need a jacket for the 2.3°C / 36°F nights, but you get more dry hours than a May trip at a lower price. November is cheaper still and nearly as dry (39.5mm over 9 days), but at 6.8°C / 44°F it is a coat-and-museums trip rather than a walking trip.

Is Toronto too hot in July?

28.2°C / 83°F is warm but not extreme — the harder number is the 19.8°C / 68°F overnight low, which means the city doesn't cool down after dark. If your accommodation has air conditioning, July is comfortable and the rain is minimal in volume (35.5mm across the month). If it doesn't, you will sleep badly. Check before you book, and plan outdoor activity for mornings and after 6pm.

How bad is Toronto in winter, really?

The number to focus on is the daily high: -2.6°C / 27°F in January and -2.3°C / 28°F in February. Because the high stays below freezing, snow and ice don't melt off during the day the way they do in cities with above-freezing afternoons. With -8°C / 17°F lows, uncovered skin gets uncomfortable in minutes once there is wind off the lake. It's a manageable trip with the right gear — insulated waterproof boots, a windproof coat, gloves, hat — and the underground PATH network covers a lot of downtown, but it is not a walking-tour city in February.

Which is better for a Toronto trip, September or June?

September, narrowly. June is 2.8°C warmer (24.7°C / 76°F vs 21.9°C / 71°F) with more daylight, which matters if beach and island time is the priority. September is drier where it counts — 36.6mm over 7 days versus 62.2mm over 10 — and its 21.9°C / 71°F is close to ideal for a day spent walking. September also has fewer summer crowds. Choose June if you want long evenings and water; choose September if you want to walk the city and not think about the weather.
