Weather in Kingston in July

A good month. July is a solid month to be in Kingston. You should expect rain on 16 days of the month, which is more days wet than dry.

July ranks 4 of 12 in Kingston: past the worst of the year but short of September, which is the month to book if the dates are open.

This is persistent light rain rather than storms: 16 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: it never really gets hot: not one day in an average July reaches 30 °C; the day barely swings — 5.6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 31.9 °C and the coldest night fell to 9.4 °C.

July is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest July on record still delivered 140 mm against 35 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 80 mm average is a reasonable planning figure, not a promise.

Wind is light at 6.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 79%, high enough to notice on the warm days without dominating them.

How July sits in the year

Temperatures hold steady either side: 20.2 °C in June, 24 here, 24.4 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Kingston's year: 15.2 hours of daylight, losing 0.7 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

With no coast nearby, the year swings a fair way — 31.6 °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.

July in Kingston versus nearby

If Kingston is one option among several, the nearby comparison is worth making. Ottawa is close enough to be a coin toss — 2 °C warmer, the same number of rain days. Peterborough is close enough to be a coin toss — 4.5 °C warmer, 4 days less rain.

So: July is effectively as good as it gets here — 4 points behind September, which is inside the margin where the weather stops being the deciding factor and price starts being it.
