Taiwan Weather Outlook: Hot Holiday Ahead, Potential Typhoon Activity End of Month

Taiwan is bracing for a typical summer weather pattern during the upcoming Dragon Boat Festival holiday, characterized by high temperatures and scattered afternoon showers. The traditional梅雨 (Meiyu) rainy season seems to have concluded, giving way to the influence of a strengthening Pacific high-pressure system.

According to the weather fan page "Taiwan Typhoon Forum | Weather Express," the period from Friday, June 19, to Wednesday, June 24, will see the Pacific high-pressure system increasingly enveloping Taiwan. This will result in hot and muggy conditions across the island. Northern and eastern regions can expect localized afternoon thunderstorms, while central and southern areas might experience isolated showers in the early morning and thunderstorms in mountainous areas and nearby plains in the afternoon.

The holiday begins as the Pacific high-pressure system gradually extends westward and strengthens, returning Taiwan's weather to the familiar summer pattern. This year's梅雨 (Meiyu) rainy season has largely concluded. If there are no special changes in the atmospheric circulation, it will be followed by afternoon thunderstorms and the typhoon season.

Looking ahead, the forum noted that a tropical disturbance, designated 92W, located near Guam, is continuing to develop. There is a possibility it could strengthen into a tropical depression over the weekend. Current forecasts suggest it may move north of the Ryukyu Islands next week, with models indicating a potential northward turn. However, the exact path and timing of any轉向 (turn) remain uncertain as tropical systems develop and atmospheric circulation adjusts.

Significantly, forecasters are pointing to a potential increase in typhoon activity in the Northwest Pacific towards the end of June. This outlook suggests that the transition from the rainy season to the typhoon season may be marked by a more active period of tropical cyclone development.

The Northwest Pacific has the potential to enter a period of active typhoons at the end of this month.
