Weather in Dallas in January

A good month. January is a solid month to be in Dallas. Highs sit at 13.3 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

January ranks 7 of 12 in Dallas: past the worst of the year but short of November, which is the month to book if the dates are open.

Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Layers, and a genuinely waterproof outer — at 13.3 °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: 13 nights fall below freezing. Across the twenty years measured, the hottest January day reached 28.1 °C and the coldest night fell to -10.8 °C, and the wettest single day dropped 55 mm — roughly 95% of the month's rain in one day.

January is moderately variable: 6 mm in the driest year against 145 mm in the wettest, around an average of 58 mm. Roughly two Januarys in three land near that average, and the third does something else entirely.

Wind is light at 11.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 73%.

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 Dallas's year — 10.2 hours of daylight against 14.3 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 — 35.1 °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 Dallas versus nearby

If Dallas is one option among several, the nearby comparison is worth making. Shreveport is close enough to be a coin toss — within a degree on temperature, 3 days more rain. Oklahoma City is the weaker option in January — 4 °C cooler, 2 days less rain.

So: January is a compromise. November is 21 points better and is what Dallas is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
