Weather in Atlanta in July

A hard month. July asks something of you. Go in knowing what. You should expect rain on 19 days of the month, which is more days wet than dry.

July ranks 12 of 12 — near the bottom of Atlanta's year. October is the month that works, and the swing between the two is 46 points, which is a different holiday rather than a slightly better one.

Rain on 19 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 32.6 °C days and 20.9 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 7 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest July day reached 41.3 °C and the coldest night fell to 13.7 °C, and the wettest single day dropped 76 mm — roughly 64% of the month's rain in one day.

July is moderately variable: 61 mm in the driest year against 294 mm in the wettest, around an average of 118 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind is light at 3.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 71%.

How July sits in the year

Temperatures hold steady either side: 30.7 °C in June, 32.6 here, 32.5 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Atlanta's year: 14.2 hours of daylight, losing 0.5 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 — 32.8 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

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

July in Atlanta versus nearby

If Atlanta is one option among several, the nearby comparison is worth making. Huntsville is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Montgomery is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: July is a compromise. October is 46 points better and is what Atlanta is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
