The plum rain season in Taiwan typically occurs in May and June each year. Due to frontal systems, unstable air currents combined with abundant moisture, the Snow Mountain National Park Administration reminds outdoor enthusiasts to pay special attention to weather forecasts. If there is a possibility of heavy rain or thunderstorms, it is best to avoid venturing into the mountains — or “clashing with the plum rains” — to ensure personal safety.
The mountain climate between spring and summer is especially unpredictable, resembling fog, rain, and wind all at once. Continuous rainfall brought by the plum rains can cause the soil and rocks in the mountains to become loose, increasing the risk of landslides and falling rocks. Trails also tend to be muddy and slippery, and reduced visibility due to rain and fog adds to the difficulty and danger of hiking activities.
Without proper waterproofing measures during windy and rainy conditions, even in summer, hypothermia can occur. If any team member shows signs of hypothermia, immediate action must be taken, such as finding shelter to rest or set up camp, changing into dry clothes to keep the body warm and dry, consuming hot food, or using external warmth. In cases of severe hypothermia, the patient should be taken down the mountain to receive medical treatment as soon as possible, as it may otherwise lead to unconsciousness or even death.
The Snow Mountain Administration also reminds visitors to treat rainfall as a normal mountain climate condition. It is essential to waterproof all items and clothing that must not get wet, and to carry a two-piece rain suit, avoiding the use of poncho-style raincoats.
Additionally, plum rain-type rainfall is often accompanied by thunderstorms. There have been past incidents where hikers on the Holy Ridge Trail were unfortunately struck by lightning and lost their lives. Special precautions against lightning strikes are necessary. Once thunderstorms occur in the mountains, it is safer to take shelter in mountain huts or buildings. Tents offer no protection, so do not stay on high ground or mountaintops. Move to lower elevations or mid-slopes, avoid tall isolated objects and large trees, and refrain from wearing clothes soaked with sweat or rain. Any potentially conductive items on your person should be quickly stowed in your backpack.
The climbing season has now begun. Recently, the Snow Mountain Administration has noticed during permit reviews that some hikers shorten their itineraries in order to secure mountain hut bookings or reduce the number of leave days. However, sudden weather changes and altitude acclimatization can put team members at high risk of altitude sickness. The Administration once again urges everyone not to underestimate any symptoms that may indicate altitude sickness.
