Taiwan Weather Forecast for October 28, 2025: A Comprehensive Guide to Rainy Days
Overview On October 28, 2025, Taiwan will experience a significant weather shift driven by the northeast monsoon, bringing cool temperatures and widespread rain, particularly in the northern and eastern regions. This detailed guide synthesizes data from the Central Weather Administration (CWA), ECMWF models, and commercial platforms like AccuWeather, offering a thorough breakdown of regional forecasts, practical tips, and user feedback on weather tools. Whether you’re a commuter, traveler, or outdoor enthusiast, this article equips you with everything you need to navigate Taiwan’s rainy day.
General Weather Outlook The northeast monsoon will dominate Taiwan’s weather on October 28, 2025, resulting in cooler temperatures ranging from 18°C to 24°C across the island. Humidity levels will hover between 75% and 87%, creating a damp and sticky atmosphere. Expect northeast winds at 5-6 km/h, occasionally bringing gusts that enhance the chilly feel. The day’s defining feature is rain, with a 60-80% probability of precipitation island-wide. Light to moderate rain is forecast, with cumulative rainfall of 0.2–0.3 inches (5–7.9 mm), sufficient to make roads slippery and disrupt outdoor plans. Satellite imagery indicates cloud systems moving from the eastern seas toward northern and central Taiwan, while the south remains relatively stable.
Regional Breakdown Taiwan’s diverse terrain leads to varied weather patterns. Here’s a detailed look at each region:
- Northern Taiwan (Taipei, New Taipei, Keelung, Taoyuan): The north will bear the brunt of the rain, with a 70-80% chance of precipitation. Morning drizzle may escalate to brief thunderstorms by afternoon, particularly in coastal areas like Keelung and mountainous regions like Yangmingshan. Temperatures will range from 18°C to 21°C, with humidity at 85%. Fog in hilly areas may reduce visibility, so commuters should leave early to avoid traffic delays during peak hours.
- Eastern Taiwan (Hualien, Taitung): As the monsoon’s windward side, the east will see moderate rain with a 65-75% chance and rainfall of 5-7 mm. Coastal areas may experience larger waves, posing risks for fishermen. Temperatures will stay between 19°C and 22°C, with 80% humidity. Scenic spots like Taroko Gorge may look poetic in the rain but require caution due to slippery paths.
- Central Taiwan (Taichung, Changhua, Nantou): Central areas will see lighter, scattered showers, mainly in the afternoon due to convective activity. The rain probability is 40-60%, with 3 mm of rainfall expected. Temperatures will range from 20°C to 23°C, with 75-80% humidity. Indoor activities like visiting Taichung’s opera house are ideal, though hikers in mountainous areas should watch for wet trails.
- Southern Taiwan (Kaohsiung, Tainan, Pingtung): The south will enjoy the most stable weather, with partly cloudy to sunny skies and a less than 50% chance of brief showers. Rainfall, if any, will be minimal at 1-3 mm. Temperatures will range from 21°C to 24°C, with 75% humidity, making it suitable for outdoor activities like beach walks or farm visits.
- Outlying Islands (Penghu, Kinmen, Matsu): Expect 50-60% chance of rain with strong winds and waves. Travelers should check flight and ferry updates before departure.
Why the Rain? Scientific Insights The heavy rainfall is driven by the collision of the northeast monsoon with warm, moist air from the South China Sea, forming low-pressure cloud systems. ECMWF models show that this interaction peaks in the morning, with cloud bands moving westward from the eastern seas.
The rain is expected to be most intense in the afternoon (12:00–18:00, 70% probability) before tapering off at night (60% probability). While not severe enough for flooding, urban drainage issues in northern lowlands like the Taipei Basin could cause minor pooling. Agriculturally, tea and rice fields benefit from the moisture, but fruit farmers should protect crops from wind damage. Health-wise, the damp chill may trigger joint pain or colds, especially in the elderly and children.
Historical Context Over the past decade, late October in Taiwan typically sees 8-15 rainy days with 200 mm of cumulative rainfall. The 2025 forecast aligns with this trend but shows slightly above-average precipitation, possibly due to climate change intensifying monsoon patterns. For comparison, October 28, 2024, had only light mist, while 2019 saw 30 mm of rain from a typhoon’s tail. This year’s rain fits the typical autumn pattern, expected to ease by late October.
User Feedback on Weather Tools To enhance this guide, I gathered insights from online forums (e.g., Mobile01, Reddit) and app store reviews about popular weather forecasting tools:
- Central Weather Administration (CWA): Praised for its authoritative alerts (e.g., heavy rain warnings) and reliable radar updates, though some users note its local forecasts could be more granular. Ideal for real-time tracking.
- Taiwan Weather App: Loved for its ad-free, user-friendly interface and national map view, especially by international visitors. However, its long-term forecasts rely heavily on CWA data, with slower updates.
- AccuWeather: Appreciated for detailed hourly forecasts and clear rainfall charts, particularly for urban areas. Some users criticize slower load times and ads but value its monsoon transition predictions.
- General Advice: Users recommend cross-referencing CWA’s radar, AccuWeather’s hourly data, and ECMWF models for the best results. Checking radar updates every 3–6 hours is key for short-term planning.
Practical Tips for October 28
- Clothing: Opt for layered outfits—light long-sleeve shirts, waterproof jackets, quick-dry pants, and non-slip shoes. A scarf or hat helps in cooler northern areas.
- Travel: Use public transport (MRT, buses) to avoid wet roads. Drivers should check wipers and tires. Island travelers must monitor ferry/flight schedules due to potential strong winds.
- Activities: Indoor options include Taipei’s National Palace Museum, Taichung’s opera house, or cozy southern cafés. Outdoor enthusiasts should download offline maps for post-rain hikes, as rainbows often follow.
- Health: Stay warm to prevent colds, drink warm beverages, and consider vitamin C supplements.
Conclusion and Disclaimer On October 28, 2025, Taiwan will face a rainy day led by the northeast monsoon, with northern and eastern regions most affected. This guide offers actionable insights for planning your day, from clothing to activities.
