Weather in Jacksonville in March

Prime time. If you get to pick your dates, March is the one. Highs average 23.3 °C, lows 10.8 °C, and rain falls on 9 days — nothing in the month is working against you.

March ranks 5 of 12 in Jacksonville: past the worst of the year but short of November, which is the month to book if the dates are open.

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 March day reached 35.1 °C and the coldest night fell to -3.5 °C, and the wettest single day dropped 68 mm — roughly 83% of the month's rain in one day.

March is moderately variable: 14 mm in the driest year against 199 mm in the wettest, around an average of 82 mm. Roughly two Marchs in three land near that average, and the third does something else entirely.

Wind is light at 2.4 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 March sits in the year

The month is on the way up: 3.3 °C warmer than February, and April adds another 4.1 °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 Jacksonville'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 20 °C in March — swimmable, but it takes a moment to commit. The sea peaks at 28.4 °C in August and bottoms out at 19.5 °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.

March in Jacksonville versus nearby

If Jacksonville is one option among several, the nearby comparison is worth making. Tallahassee is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Tampa is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

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.
