Weather in Houston
Houston has a humid subtropical climate, prevailing winds
bringing in the heat from the deserts of Mexico and moisture from
the Gulf of Mexico during most of the year. Summers are
swelteringly hot and humid, making air-conditioning a necessity
rather than a luxury. Summers are characterised by afternoon
thunderstorms, which bring rain most days, and sometimes tornadoes.
Winters, by contrast, are cool and temperate, with no snow but some
rain. The coolest month is January.
