Weather in New Orleans in June

Shoulder season. June sits in between. You will get good days and you will lose some. You should expect rain on 19 days of the month, which is more days wet than dry.

June ranks 10 of 12 — near the bottom of New Orleans's year. November is the month that works, and the swing between the two is 35 points, which is a different holiday rather than a slightly better one.

Rain on 19 days, 5 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 30.3 °C days and 25.6 °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: 16 days top 30 °C — hot spells arrive, but they break; the day barely swings — 4.7 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 36.2 °C and the coldest night fell to 19.8 °C, and the wettest single day dropped 108 mm — roughly 61% of the month's rain in one day.

June is moderately variable: 42 mm in the driest year against 455 mm in the wettest, around an average of 176 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind is light at 10.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 76%, high enough to notice on the warm days without dominating them.

How June sits in the year

Temperatures hold steady either side: 27.5 °C in May, 30.3 here, 30.7 in July. Nothing about the timing within the month matters much. Rain is the thing that moves: July brings 5 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in June

June is at or near the longest days of New Orleans's year: 14.1 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

Despite being inland, the year stays fairly even: 22.3 °C between the year's warmest afternoons and coldest nights.

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.

June in New Orleans versus nearby

If New Orleans is one option among several, the nearby comparison is worth making. Baton Rouge is the weaker option in June — 2.3 °C warmer, 1 day less rain. Mobile is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: June is a compromise. November is 33 points better and is what New Orleans is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
