Weather in Mobile in October

Prime time. If you get to pick your dates, October is the one. Highs average 25.8 °C, lows 18.5 °C, and rain falls on 9 days — nothing in the month is working against you.

October ranks 2 of 12 in Mobile. Only November scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 9 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest October day reached 34.4 °C and the coldest night fell to 6.7 °C, and the wettest single day dropped 75 mm — roughly 74% of the month's rain in one day.

October is moderately variable: 3 mm in the driest year against 240 mm in the wettest, around an average of 101 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.

Wind is light at 10.3 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 October sits in the year

The month is on the way down: 3.9 °C cooler than September, with November dropping another 5 °C. The first week and the last are not the same trip. Rain has already shifted: 5 days fewer than September had.

Daylight in October

11.5 hours of daylight, losing 0.9 hours across the month. That is between Mobile's extremes of 14.1 and 10.2 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 26.6 °C in October — warm enough to stay in as long as you like. The sea peaks at 29.8 °C in August and bottoms out at 19 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

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.

October 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, the same number of rain days. Montgomery is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: October is effectively as good as it gets here — 2 points behind November, which is inside the margin where the weather stops being the deciding factor and price starts being it.
