Weather in Baton Rouge in July

United States · 20-year averages, July

A hard month. July asks something of you. Go in knowing what. You should expect rain on 23 days of the month, which is more days wet than dry.

July ranks 11 of 12 — near the bottom of Baton Rouge's year. November is the month that works, and the swing between the two is 42 points, which is a different holiday rather than a slightly better one.

Rain on 23 of the month's 31 days, 4 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Pack for 32.7 °C days and 23.5 °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: 6 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest July day reached 40.3 °C and the coldest night fell to 17.7 °C, and the wettest single day dropped 75 mm — roughly 49% of the month's rain in one day.

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 227 mm against 85 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 152 mm average is a reasonable planning figure, not a promise.

Wind is light at 4.1 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: 32.6 °C in June, 32.7 here, 32.8 in August. Nothing about the timing within the month matters much. Rain has already shifted: 5 days more than June had.

Daylight in July

July is at or near the longest days of Baton Rouge's year: 13.9 hours of daylight, losing 0.4 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 — 28.5 °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 Baton Rouge versus nearby

If Baton Rouge is one option among several, the nearby comparison is worth making. New Orleans is a better bet in July — 2 °C cooler, 1 day more rain. Jackson is close enough to be a coin toss — within a degree on temperature, 5 days less rain.

So: July is a compromise. November is 42 points better and is what Baton Rouge is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
