Weather in Amarillo in March

Prime time. March is about as good as Amarillo gets. Highs average 18.7 °C, lows 2.5 °C, and rain falls on 4 days — nothing in the month is working against you.

March ranks 2 of 12 in Amarillo. Only April scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain falls on only 4 days, so an itinerary with no wet-weather fallback is a reasonable risk. 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; 9 nights fall below freezing; the day swings 16.2 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest March day reached 32.1 °C and the coldest night fell to -11.3 °C, and the wettest single day dropped 33 mm — roughly 106% of the month's rain in one day.

This is the volatile part. March rainfall has ranged from 3 mm to 121 mm across the twenty years measured — a 118 mm spread around an average of 31 mm. The average is real but almost no individual March looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 14.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 49%.

How March sits in the year

The month is on the way up: 5.7 °C warmer than February, and April adds another 4.8 °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 1.1 hours across the month. That is between Amarillo's extremes of 14.5 and 9.8 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 37.1 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. At 1118 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly. Within March itself the daily swing is 16.2 °C, so mornings and afternoons need different clothes.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, May is the trade worth considering — 14 points weaker on weather, and materially quieter.

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

March in Amarillo versus nearby

If Amarillo is one option among several, the nearby comparison is worth making. Lubbock is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Oklahoma City is the weaker option in March — within a degree on temperature, 3 days more rain.

So: March is effectively as good as it gets here — 3 points behind April, which is inside the margin where the weather stops being the deciding factor and price starts being it.
