Weather in Tulsa in January

A hard month. January asks something of you. Go in knowing what. Highs sit at 8.4 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

January ranks 9 of 12 in Tulsa: past the worst of the year but short of October, which is the month to book if the dates are open.

Rain falls on only 5 days, so an itinerary with no wet-weather fallback is a reasonable risk. Layers, and a genuinely waterproof outer — at 8.4 °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: 23 nights drop below freezing, so anything left outside stays frozen. Across the twenty years measured, the hottest January day reached 24.5 °C and the coldest night fell to -22.1 °C, and the wettest single day dropped 40 mm — roughly 89% of the month's rain in one day.

January is moderately variable: 3 mm in the driest year against 108 mm in the wettest, around an average of 45 mm. Roughly two Januarys in three land near that average, and the third does something else entirely.

Wind is light at 12.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 75%, which at 8.4 °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 Tulsa's year — 9.9 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 — 37.2 °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 Tulsa versus nearby

If Tulsa is one option among several, the nearby comparison is worth making. Oklahoma City is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Wichita is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: January is a compromise. October is 33 points better and is what Tulsa is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
