Weather in Mobile in March

Prime time. March is about as good as Mobile gets. Highs average 20 °C, lows 13 °C, and rain falls on 10 days — nothing in the month is working against you.

March ranks 4 of 12 in Mobile: past the worst of the year but short of November, which is the month to book if the dates are open.

Rain on 10 days, 4 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

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average March reaches 30 °C. Across the twenty years measured, the hottest March day reached 27.5 °C and the coldest night fell to -0.3 °C, and the wettest single day dropped 134 mm — roughly 111% of the month's rain in one day.

March is moderately variable: 16 mm in the driest year against 300 mm in the wettest, around an average of 121 mm. Roughly two Marchs in three land near that average, and the third does something else entirely.

Wind is light at 10.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 82%, high enough to notice on the warm days without dominating them.

How March sits in the year

The month is on the way up: 3.1 °C warmer than February, and April adds another 3.6 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in March

11.9 hours of daylight, gaining 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 19.9 °C in March — swimmable, but it takes a moment to commit. 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

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

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

So: March is effectively as good as it gets here — 5 points behind November, which is inside the margin where the weather stops being the deciding factor and price starts being it.
