Weather in Amarillo in October

Prime time. October is about as good as Amarillo gets. Highs average 22.9 °C, lows 8.1 °C, and rain falls on 6 days — nothing in the month is working against you.

October ranks 3 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 6 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

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest October day reached 34.8 °C and the coldest night fell to -7.2 °C, and the wettest single day dropped 56 mm — roughly 108% of the month's rain in one day.

October is moderately variable: 5 mm in the driest year against 124 mm in the wettest, around an average of 52 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.

Wind is light at 12.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 55%.

How October sits in the year

The month is on the way down: 6.5 °C cooler than September, with November dropping another 6.5 °C. The first week and the last are not the same trip.

Daylight in October

11.4 hours of daylight, losing 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 October itself the daily swing is 14.8 °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.

October 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, the same number of rain days. Oklahoma City is close enough to be a coin toss — within a degree on temperature, 2 days more rain.

So: October 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.
