Weather in Houston in October

A good month. October is a solid month to be in Houston. Highs average 28.2 °C, lows 16.1 °C, and rain falls on 10 days — nothing in the month is working against you.

October ranks 6 of 12 in Houston: past the worst of the year but short of March, which is the month to book if the dates are open.

Rain on 10 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 28.2 °C days and 16.1 °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 top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest October day reached 35.9 °C and the coldest night fell to 2.5 °C, and the wettest single day dropped 116 mm — roughly 91% of the month's rain in one day.

October is moderately variable: 4 mm in the driest year against 368 mm in the wettest, around an average of 128 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.

Wind is light at 6.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 75%, high enough to notice on the warm days without dominating them.

How October sits in the year

The month is on the way down: 4 °C cooler than September, with November dropping another 5.8 °C. The first week and the last are not the same trip.

Daylight in October

11.5 hours of daylight, losing 0.9 hours across the month. That is between Houston's extremes of 14 and 10.2 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 30 °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.

October in Houston versus nearby

If Houston is one option among several, the nearby comparison is worth making. Corpus Christi is close enough to be a coin toss — within a degree on temperature, 2 days less rain. San Antonio is close enough to be a coin toss — within a degree on temperature, 3 days less rain.

So: October works, with March the better month by 10 points if the dates can move. If they cannot, nothing here should stop you booking.
