10月のヒューストンについての旅行者の声
Regulars widely call this the year's best weather month, with humidity noticeably lower than the stifling summer stretch that runs through September, though they're honest this is relative - someone who genuinely dislikes humidity may still find it uncomfortable even by the city's own improved standard. Our row backs that read, 29C over 18.4C nights, with 82.4mm of rain across 6.4 days. Regulars note early-month days can still push into the high 80s or low 90s Fahrenheit before a cold front typically arrives later in the month to cool things down, and that hurricane risk has largely passed by this point, with the more serious storm activity concentrated in August and September instead. The record: humidity 72 percent, 9 hours of sun, a 16.3 kph wind and AQI 45.

Regulars call February one of this city's two worst-behaved months, alongside January, and describe a real split within it: early in the month lows can sit in the mid-30s to 50s Fahrenheit, while late February can swing to highs in the mid-50s to 70s. Our row averages across that at 20.7C reading as 20C over 10C nights, with 79.3mm of rain across 7.7 days - and a trace of snow, 0.6cm, that most years never lands. Whichever half of the month you land in depends on how far south a Canadian cold front has pushed, which is the honest reason no single number describes it well. Humidity stays real even in the cooler stretch, and Houston's own line for it is warm-feeling sixties and seventies. The record: 6.7 hours of sun, a 20.3 kph wind and AQI 44.
April is one of the three months regulars name for outdoor plans here, alongside March and November, and their instruction is layers you can shed: a late cold front can still come through and drop the temperature sharply for a day. Our row gives 26.8C reading as 28C over 16.6C nights, with 76.4mm across 5.7 days. The number that separates this from Austin two hundred miles west is humidity - 75 percent here against 68 there, on nearly identical temperatures - and it is why the same 27C feels heavier. Their other rule is negative and firm: do not come in summer. The record: a dew point of 14.7C, 9.2 hours of sun, a 21.4 kph wind and AQI 43.
March is the month Houston regulars name without hesitation: outside hurricane season, relatively dry, and sunny enough that mid-70s Fahrenheit days are the expectation, with lows nearer 50F. What they warn about is the swing inside a single day - you can start in jeans and a sweatshirt and be out of the sweatshirt by ten in the morning - so the packing is layers and a lined windbreaker rather than a heavy coat. The one thing March will not give you is the Gulf: the water at Galveston is still too cold to swim in and the beach can be blustery. The other thing to know is that the rodeo and the local school spring break both land mid-month. The record: 24.5C days, 14.2C nights, 4.8 precipitation days carrying 75.3mm and 8.3 hours of sun.
Houston forum threads describe January as one of the city's least predictable months, with daytime highs commonly in the 40s-50s Fahrenheit and overnight lows dropping into the 20s-30s, but posters were direct that a warm, nearly 70F day can be followed almost immediately by a hard freeze. Rain was flagged as a recurring feature too, coming and going through the month rather than settling into a single wet or dry stretch. The universal advice across threads: pack layers for both cold and mild conditions and check the forecast close to your travel dates, since January and February were repeatedly named the city's two toughest weather months to plan around.

- 要注意
Mosquito season
5月1日〜10月31日 · 例年虫・感染症Harris County runs one of the largest mosquito control operations in the country and still sprays by air after a wet week. Anything on a bayou trail or a patio needs repellent until the first front arrives. 出典 ↗
- 要注意
Atlantic hurricane season
6月1日〜11月30日The risk concentrates from mid-August into September. The bigger and more frequent problem here is not the wind but the rainfall: this is a flat city that floods on a stalled storm. 出典 ↗

The first cool fronts
10月15日〜12月10日 · 例年乾季From mid-October the fronts start reaching the coast and the humidity finally breaks. Late autumn is the best stretch of the year here and almost nobody books it.
