Weather in Mobile in 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 12 of 12 — near the bottom of Mobile's year. November is the month that works, and the swing between the two is 37 points, which is a different holiday rather than a slightly better one.

Rain on 23 of the month's 31 days, 6 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 31.2 °C days and 26 °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: 23 days top 30 °C, making the heat continuous rather than occasional; the day barely swings — 5.2 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 36.2 °C and the coldest night fell to 21.4 °C, and the wettest single day dropped 63 mm — roughly 35% of the month's rain in one day.

July is one of the reliable ones — rainfall has stayed between 109 mm and 270 mm across all twenty years, a narrow enough band that the 180 mm average is something you can plan against rather than merely quote.

Wind is light at 8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 77%, high enough to notice on the warm days without dominating them.

How July sits in the year

Temperatures hold steady either side: 30.5 °C in June, 31.2 here, 31.1 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 Mobile's year: 14 hours of daylight, losing 0.4 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 29.5 °C in July — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

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 Mobile versus nearby

If Mobile is one option among several, the nearby comparison is worth making. New Orleans is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Montgomery is close enough to be a coin toss — 2.1 °C warmer, 5 days less rain.

So: July is a compromise. November is 37 points better and is what Mobile is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
