Taiwan weather: June to be wet, July-August hot, forecasters say

Taiwan's Central Weather Administration has released its "Seasonal Long-Term Weather Outlook" for the next three months, forecasting a wetter June followed by hotter conditions through August.

June is characterized as a plum rain season, with the potential for localized heavy downpours as weather fronts linger. The administration anticipates a shift to a typical summer weather pattern by mid-to-late June as fronts move northward. July and August are expected to be hot and sunny, influenced by the Pacific subtropical high-pressure system, with occasional afternoon thunderstorms.

Additionally, the typhoon season is set to begin in July, with the western North Pacific typically seeing increased activity. On average, July sees about 3.7 typhoons form, with 0.8 affecting Taiwan, while August averages 5.5 formations and 0.9 impacting Taiwan. The administration noted that current tropical Pacific and atmospheric circulation patterns have returned to normal, with warming sea surface temperatures in the equatorial central and eastern Pacific, suggesting a potential development towards El Niño conditions over the summer.

Regarding precipitation, models predict drier conditions in the ocean and continent, and active convection east of the Philippines. Taiwan and the South China Sea are expected to be wetter in June, but drier in July and August. However, the forecast carries significant uncertainty due to the onset of the typhoon season.
