Weather in Houston in April

Prime time. April is about as good as Houston gets. Highs average 26.7 °C, lows 15.2 °C, and rain falls on 8 days — nothing in the month is working against you.

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

Rain on 8 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. 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: 5 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest April day reached 36.5 °C and the coldest night fell to 1.4 °C, and the wettest single day dropped 96 mm — roughly 110% of the month's rain in one day.

April is moderately variable: 10 mm in the driest year against 262 mm in the wettest, around an average of 87 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 7.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 77%, high enough to notice on the warm days without dominating them.

How April sits in the year

The month is on the way up: 3.8 °C warmer than March, and May adds another 4.2 °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

12.9 hours of daylight, gaining 0.8 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

Peak season. Expect the highest prices of the year and to be booking well ahead.

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

April 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 — 2.6 °C warmer, 2 days less rain. San Antonio is close enough to be a coin toss — 2.4 °C warmer, 2 days less rain.

So: April is effectively as good as it gets here — 0 points behind March, which is inside the margin where the weather stops being the deciding factor and price starts being it.
