Weather in Buffalo in August

United States · 20-year averages, August

A good month. August is a solid month to be in Buffalo. Highs average 26.8 °C, lows 17.3 °C, and rain falls on 14 days — nothing in the month is working against you.

August is the highest-scoring month of the twelve. The nearest rival is September, and the month at the other end of the year is January.

This is persistent light rain rather than storms: 14 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: 4 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest August day reached 34.6 °C and the coldest night fell to 11.1 °C, and the wettest single day dropped 55 mm — roughly 70% of the month's rain in one day.

August is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest August on record still delivered 125 mm against 43 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 79 mm average is a reasonable planning figure, not a promise.

Wind is light at 4.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 70%.

How August sits in the year

Temperatures hold steady either side: 27.2 °C in July, 26.8 here, 23.3 in September. Nothing about the timing within the month matters much.

Daylight in August

14 hours of daylight, losing 1.3 hours across the month. That is between Buffalo's extremes of 15.3 and 9 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 34.1 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

August in Buffalo versus nearby

If Buffalo is one option among several, the nearby comparison is worth making. Hamilton is close enough to be a coin toss — 2 °C warmer, 3 days less rain. Toronto is close enough to be a coin toss — 2.6 °C cooler, 1 day less rain.

So: August is the answer for Buffalo. If it is booked out or priced out, September is the next best thing at 0 points behind, and January is the month to keep off the shortlist.
