Taiwan Weekly Weather Update: After the Meiyu front passes, the weather will turn sunny, and temperatures will rise to 33 degrees Celsius.

From May 10 to 11, the second wave of the plum rain season is expected to affect Taiwan, with frequent rainfall in Yilan and Hualien, accompanied by brief heavy rain and localized downpours. Starting on the 12th, the front is expected to move south towards the Bashi Channel, and the weather will turn clear, with temperatures rising between 21 and 33 degrees Celsius, and nighttime temperatures ranging from 19 to 30 degrees. For the coming week, wind speeds are expected to be 2 to 3 on the Beaufort scale, with no strong wind forecast. There may be occasional thunderstorms in the mountainous areas in the afternoon, so caution is advised for potential landslides in mountainous areas and water accumulation in low-lying regions.

May 10-11: Meiyu Front Impact - Rain Across Taiwan, Cooler in the North

Starting May 10 (Saturday), the second wave of the Meiyu front will affect Taiwan from north to south, causing unstable weather across the island. The western and northeastern regions will experience scattered showers or thunderstorms, with a chance of localized heavy rain or torrential rain. Hualien has already seen torrential rain, leading the Meteorological Bureau to issue a heavy rain warning, which was later lifted in the evening. Kinmen and Matsu will have scattered brief showers.

Regarding temperatures, daytime highs in the northern region will drop to 19-25°C, central 21-27°C, southern 24-30°C, and eastern 21-26°C. The strengthening northeast wind will cool down areas from central to northern Taiwan, as well as Yilan and Hualien, with nighttime lows generally between 19-21°C.

May 11 (Sunday) is Mother's Day, and the front will continue to affect Taiwan, extending the rain to central and southern regions, Taitung, and mountainous areas, with a chance of localized torrential rain. The Meteorological Bureau warns that severe convective weather may bring lightning, strong gusts, and brief heavy rainfall. Mountainous areas should be wary of landslides and rising streams, while low-lying areas should watch for water accumulation.

May 12: Front Moves South - Clearer in the North, Localized Rain in the South

On May 12 (Monday), the front will move south to the Bashi Channel, with weather gradually turning cloudy to clear in the northern, central, and northeastern regions. The southern and southeastern regions will still have localized brief showers or thunderstorms, with scattered rain possible in the afternoon in mountainous areas.

Temperatures will rise, with daytime highs reaching 28°C in the north, 29°C in the central region, 27°C in the south, and 25°C in the east. Nighttime lows will range between 18-23°C. Winds will shift to an easterly direction, maintaining a speed of 2-3 on the Beaufort scale.

May 13-14: Stable Weather - Larger Day-Night Temperature Difference

Starting May 13 (Tuesday), winds will shift to a southeast direction, significantly reducing moisture. Most of Taiwan will experience cloudy to clear weather, with localized brief thunderstorms in the afternoon in mountainous areas. On May 14 (Wednesday), the weather will remain stable, with only the southeastern region and Hengchun Peninsula experiencing localized brief showers, and thunderstorms still possible in the afternoon in mountainous areas.

Regarding temperatures, daytime highs in the western half will generally exceed 30°C, reaching 32°C in the north, 31°C in the central region, and 33°C in the south; the eastern and southeastern regions will be 28-30°C. Nighttime temperatures will range from 20-24°C, with a noticeable day-night temperature difference, so it's advisable for those heading out early or returning late to dress in layers.

May 15-16: Southern Winds Bring Afternoon Thunderstorms

Starting May 15 (Thursday), winds will shift to a southern direction, slightly increasing moisture. The southern and southeastern regions will have localized brief showers, while other areas will be mostly cloudy to clear, with localized brief thunderstorms in the afternoon in mountainous areas. On May 16 (Friday), the weather pattern will be similar, with a slightly increased chance of afternoon rain in the north, Yilan, Hualien, and mountainous areas.

Regarding temperatures, the north will be 23-31°C, central 23-32°C, south 24-33°C, east 23-28°C, and southeast 24-30°C. The outlying islands like Penghu, Kinmen, and Matsu will have temperatures between 22-30°C.

Wind Speed and Direction: Stable Throughout the Week - No Strong Wind Forecast

According to the Central Weather Bureau, wind speeds across Taiwan will generally remain at 2-3 on the Beaufort scale, with variable wind directions, including northerly, easterly, and southerly winds. There is no strong wind forecast, minimizing the impact on flights and maritime activities. However, Matsu may experience fog or low clouds at night and early morning from May 13-15, affecting visibility, so caution is advised for traffic safety.

Rainfall Trends and Precautions

Overall, May 10-11 will be the rainiest period of the week, with a general rainfall probability exceeding 70%, and frequent rain in Yilan and Hualien. From May 12, rainfall will ease, shifting to partly cloudy, with localized thunderstorms still possible in the afternoon in mountainous areas. The Meteorological Bureau reminds that recent mountain areas have loose soil, so caution is advised against landslides and falling rocks, and low-lying areas should also be aware of water accumulation.
