Weather in Amarillo in April

United States · 20-year averages, April

Prime time. If you get to pick your dates, April is the one. Highs average 23.5 °C, lows 6.6 °C, and rain falls on 5 days — nothing in the month is working against you.

April is the highest-scoring month of the twelve. The nearest rival is March, and the month at the other end of the year is July.

Rain falls on only 5 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: 4 days top 30 °C — hot spells arrive, but they break; the day swings 16.9 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest April day reached 37.4 °C and the coldest night fell to -5.3 °C, and the wettest single day dropped 47 mm — roughly 147% of the month's rain in one day.

April is moderately variable: 1 mm in the driest year against 86 mm in the wettest, around an average of 32 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 15.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 44%.

How April sits in the year

The month is on the way up: 4.8 °C warmer than March, and May 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 April

13 hours of daylight, gaining 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 April itself the daily swing is 16.9 °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.

April 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 — 2 °C warmer, 1 day less rain. Oklahoma City is close enough to be a coin toss — within a degree on temperature, 3 days more rain.

So: April is the answer for Amarillo. If it is booked out or priced out, March is the next best thing at 3 points behind, and July is the month to keep off the shortlist.
