Weather in Baton Rouge in March

Prime time. March is about as good as Baton Rouge gets. Highs average 22 °C, lows 10.3 °C, and rain falls on 10 days — nothing in the month is working against you.

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

Rain on 10 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

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 29.4 °C and the coldest night fell to -6.1 °C, and the wettest single day dropped 103 mm — roughly 94% of the month's rain in one day.

March is moderately variable: 20 mm in the driest year against 232 mm in the wettest, around an average of 109 mm. Roughly two Marchs in three land near that average, and the third does something else entirely.

Wind is light at 6.6 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: 3.9 °C warmer than February, and April adds another 3.8 °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 Baton Rouge's extremes of 14.1 and 10.2 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 28.5 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

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 Baton Rouge versus nearby

If Baton Rouge 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. Jackson is close enough to be a coin toss — 2.5 °C cooler, 1 day more rain.

So: March is effectively as good as it gets here — 1 points behind November, which is inside the margin where the weather stops being the deciding factor and price starts being it.
