Weather in Raleigh in January

United States · 20-year averages, January

A hard month. January asks something of you. Go in knowing what. Highs sit at 9.3 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

January ranks 10 of 12 — near the bottom of Raleigh's year. October is the month that works, and the swing between the two is 45 points, which is a different holiday rather than a slightly better one.

Rain on 9 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 9.3 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

Averages flatten a month, and this one hides a few things: 20 nights drop below freezing, so anything left outside stays frozen. Across the twenty years measured, the hottest January day reached 23.8 °C and the coldest night fell to -13.6 °C, and the wettest single day dropped 42 mm — roughly 58% of the month's rain in one day.

January is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest January on record still delivered 128 mm against 30 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 72 mm average is a reasonable planning figure, not a promise.

Wind is light at 1.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 80%, which at 9.3 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

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 Raleigh's year — 10 hours of daylight against 14.6 at midsummer, gaining 0.6 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 — 34.6 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

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

January in Raleigh versus nearby

If Raleigh is one option among several, the nearby comparison is worth making. Charlotte is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Richmond is the weaker option in January — 3.2 °C cooler, 11 days more rain.

So: January is a compromise. October is 36 points better and is what Raleigh is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
