Weather in Dallas in March

Prime time. If you get to pick your dates, March is the one. Highs average 20.4 °C, lows 8.1 °C, and rain falls on 9 days — nothing in the month is working against you.

March ranks 3 of 12 in Dallas. Only November scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 9 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 31 °C and the coldest night fell to -8.3 °C, and the wettest single day dropped 76 mm — roughly 86% of the month's rain in one day.

March is moderately variable: 5 mm in the driest year against 188 mm in the wettest, around an average of 88 mm. Roughly two Marchs in three land near that average, and the third does something else entirely.

Wind is light at 12.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 73%.

How March sits in the year

The month is on the way up: 5.1 °C warmer than February, and April adds another 4.5 °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 1 hours across the month. That is between Dallas's extremes of 14.3 and 10 hours, so days are long enough not to constrain the plan.

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

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

March 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, 2 days more rain. Oklahoma City is close enough to be a coin toss — 2.7 °C cooler, 2 days less rain.

So: March is effectively as good as it gets here — 6 points behind November, which is inside the margin where the weather stops being the deciding factor and price starts being it.
