Taiwan Weather: Showers Expected Wednesday, Clearing Skies and Heat to Follow

Taiwan is bracing for a mixed bag of weather conditions on Wednesday, June 17, 2026. The central and northern parts of the island, along with eastern mountainous areas, should prepare for showers and the possibility of localized heavy rainfall. Meanwhile, southern regions will experience intermittent rain and thunderstorms due to the influence of the southwest monsoon.

However, a significant shift is expected starting Thursday. The weather is forecast to transition to sunny skies with partly cloudy conditions across the entire island, lasting through Sunday, June 21, which marks the end of the Dragon Boat Festival holiday. Temperatures are predicted to rise daily, reaching between 33 to 35 degrees Celsius (91 to 95 degrees Fahrenheit) by the weekend, signaling a return to hot weather.

Residents are advised to be mindful of the high ultraviolet (UV) radiation levels on Wednesday, particularly in the north and central regions, where the index will be rated 'high' or 'very high.' Air quality is expected to be 'good' in most areas, except for northern and southern regions which may experience 'moderate' levels. The Central Weather Administration noted that the probability of widespread heavy rainfall is decreasing, suggesting the plum rain season may be nearing its end, barring any typhoons or strong monsoon activity.
