Taiwan’s Climate

Taiwan has a basic three season climate common in the subtropics. The island also has quite different weather from coast to coast and north-south as the high mountains separate the two coasts, and the north and south have quite different ocean currents affecting them.

North and Northeast Taiwan:
Winter arrives sometime around the end of October and brings cool and often wet weather. Prevailing winds are northerly and quite strong as consecutive cold waves arrive from China.
Summer weather begins sometime around May and brings higher temperatures, but there is still quite a lot of rain. Base wind is often southerly but that is good for setting up sea breezes at northern sites like Keelung. Good flying days happen, but don’t expect them every weekend until late June or July. The north is not as prone to typhoons as elsewhere.

East Coast:
The prevailing northerlies that arrive around November rule out any paragliding during most of the winter. Summer weather starts up around May or so and the prevailing wind shifts to the south to help push paragliders up the Huadong valley. Rain showers are frequent but are often short. There can be typhoons from February right through December, though July and August will have the most warnings posted.

Central and South Taiwan:
The wet season arrives around May and the mountains will have frequent, if not daily, showers all summer. Summer doesn’t really get any hotter, but humidity climbs steadily until summer breaks, making it very sticky and unpleasant. Thunderstorms are basically a daily event until late September or even later. Summer does not now break until late November. Winter brings low humidity, warm days and cool nights, and high cloudbases. Prevailing winds are usually northerly, but being quite light they are easily overwhelmed by local micrometerology. Typhoons can bring torrential rain at any time and strike in almost any month, most of them arriving in July or August.
