Weather in Baton Rouge in January
United States · 20-year averages, January
A good month. January is a solid month to be in Baton Rouge. Highs average 15.7 °C, lows 4.3 °C, and rain falls on 10 days — nothing in the month is working against you.
January ranks 7 of 12 in Baton Rouge: 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. Pack for 15.7 °C days and 4.3 °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: 8 nights fall below freezing. Across the twenty years measured, the hottest January day reached 26.7 °C and the coldest night fell to -8.3 °C, and the wettest single day dropped 70 mm — roughly 56% of the month's rain in one day.
January is moderately variable: 26 mm in the driest year against 355 mm in the wettest, around an average of 126 mm. Roughly two Januarys 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 84%, high enough to notice on the warm days without dominating them.
How January sits in the year
This is a turning point in the year — December and February sit on opposite sides of it, so the month contains the change rather than following it.
Daylight in January
January sits at the dark end of Baton Rouge's year — 10.4 hours of daylight against 14.1 at midsummer, gaining 0.5 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.
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
Shoulder. The value months — prices ease off and you get the place closer to itself.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
January 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, the same number of rain days. Jackson is the weaker option in January — 3.1 °C cooler, the same number of rain days.
So: January works, with November the better month by 16 points if the dates can move. If they cannot, nothing here should stop you booking.
