Weather in Amarillo in August

Shoulder season. August is shoulder season in Amarillo — cheaper, quieter, and a genuine gamble. Highs average 33.3 °C, lows 19.8 °C, and rain falls on 12 days — nothing in the month is working against you.

August ranks 11 of 12 — near the bottom of Amarillo's year. April is the month that works, and the swing between the two is 43 points, which is a different holiday rather than a slightly better one.

Rain on 12 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 33.3 °C days and 19.8 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 12 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest August day reached 42.2 °C and the coldest night fell to 11.8 °C, and the wettest single day dropped 32 mm — roughly 43% of the month's rain in one day.

August is moderately variable: 17 mm in the driest year against 179 mm in the wettest, around an average of 75 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.

Wind is light at 11.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 52%.

How August sits in the year

Temperatures hold steady either side: 34.4 °C in July, 33.3 here, 29.4 in September. Nothing about the timing within the month matters much.

Daylight in August

13.5 hours of daylight, losing 0.9 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.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

August 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, 2 days less rain. Oklahoma City is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: August is a compromise. April is 41 points better and is what Amarillo is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
