Regional weather forecasts diverged sharply ahead of Taiwan’s National Day holiday.
Rain was forecast for northern and eastern Taiwan on October 9–10, while central and southern Taiwan may feel as hot as summer during the day.
Even during the same holiday, clothing and travel plans may need to differ depending on the destination and date.
3-line summary
1. Holiday weather varies significantly by region
2. Rain in the north and Yilan; heat in central and southern Taiwan
3. Consider the itinerary separately by region and date
Rain More Pronounced Along the Northern Coast and in Yilan on the 9th–10th
According to a Yahoo News report, Taiwan’s weather authorities expected moisture to increase again on October 9 and 10 during the National Day holiday. The Greater Taipei area and Taoyuan, on the windward side, may see considerable cloud cover and occasional rain, while rain is expected to be more pronounced along the northern coast and in Yilan.
Intermittent rain was also mentioned as a possibility in eastern Taiwan’s Hualien and Taitung and on the Hengchun Peninsula. For itineraries visiting the northern coast or Yilan, it is necessary to consider rainy travel segments as well, rather than preparing mainly for clear weather.
The point to note in this forecast is that it does not say rain will occur uniformly throughout the entire holiday. The areas where rain may be concentrated were specifically identified as the northern coast and Yilan, while the Greater Taipei area and Taoyuan were described as having considerable cloud cover followed by rain.
Central and Southern Plains Will Be Hot, with Afternoon Rain Possible in Southern Mountain Areas
Central and southern Taiwan was generally forecast to be cloudy or clear. Yahoo News reported that daytime conditions in this area may feel as hot as summer. If clothing is chosen based only on thoughts of rain and cooler conditions in the north, it may not be suitable for the daytime heat on the central and southern plains.
However, brief rain may be possible in southern mountain areas during the afternoon. The forecast for generally clear conditions in central and southern Taiwan and the possibility of localized rain in mountain areas were presented together. This is why mountain itineraries should take the possibility of afternoon rain into account rather than being judged solely by the weather on the plains.
ETtoday News reported that the period from the night of the 7th to the early morning of the 8th would be when the influence of the cold air was strongest. Daytime temperatures in northern Taiwan, Yilan, and Hualien were given as 20–22 degrees, and the possibility of lower temperatures near the coast, open areas, and locations close to mountains was mentioned. This concerns the temperature change before the holiday and should be viewed separately from the forecast that moisture changes would be added after the northeast monsoon weakened during the holiday period.
From the 11th, Northern Taiwan Is Expected to Become Drier and Warm Up Again
In a Yahoo News report, weather authorities forecast that northern Taiwan would become drier and temperatures would rise again from October 11 as moisture gradually decreased. The possibility of rain in northern Taiwan during the first part of the holiday and the drying and warming trend in the latter part were changes presented for different dates.
Rather than grouping the National Day holiday under a single weather pattern, it is more appropriate to divide it into the possibility of rain in northern and eastern Taiwan on the 9th–10th, daytime heat in central and southern Taiwan, and changes in northern Taiwan from the 11th onward. In particular, the key point of this forecast is that the preparations needed for the northern coast and Yilan differ from those needed for the central and southern plains.
