Tomorrow’s Weather Forecast: A Detailed Look at Temperatures and Conditions
February 9, 2026 – This forecast provides a detailed look at the weather conditions expected across Taiwan, with a special focus on temperature fluctuations and potential impacts leading into the Lunar New Year celebrations.
Yesterday’s Temperatures (February 8th)
Yesterday saw maximum temperatures ranging from 15°C to 24°C across various regions of Taiwan.
Current Conditions (February 9th)
This morning’s observations indicate increased cloud cover in the eastern half of the island (see image below). Scattered rainfall echoes are present off the eastern coast. Rainfall is minimal across other areas. The lowest temperature recorded on the island’s plains due to this “strong continental cold air mass” was 6.0°C in Guoping Township, Yunlin County. The Taipei observation station recorded a temperature of 10.6°C, which did not meet the criteria for a “cold wave” designation. Thus, so far this winter and this year, Taiwan has only experienced one cold wave in early January (9.1°C at the Taipei station on January 9th).
Temperatures have risen slightly overnight. As of 5:22 AM, the lowest temperatures on the island’s plains were: Zhongliao, Nantou County (7.1°C), Shiding District, New Taipei City, and Wufeng District, Taichung City (7.7°C), and Guoping Township, Yunlin County (8.0°C). The lowest plain temperatures across the island range from 7°C to 9°C. Please update this information if temperatures drop further.
Today’s Forecast (February 9th)
The latest (8 PM, February 8th) European Centre for Medium-Range Weather Forecasts (ECMWF) model simulations indicate that Taiwan will be affected by the “strong continental cold air mass” today. Western Taiwan will experience clear and stable conditions, while the eastern half will see slightly more cloud cover with a chance of occasional, brief showers. Daytime temperatures will rise slightly but remain cool. Due to nighttime radiative cooling, while a full-fledged “cold wave” is not expected, parts of the island’s plains will experience temperatures below 10°C tonight and tomorrow morning. Please take precautions to stay warm and prevent cold-related harm.
Extended Forecast
The latest model simulations suggest that the cold air mass will weaken starting tomorrow afternoon (February 10th) and continue through Wednesday morning (February 11th). Conditions will be clear, and daytime temperatures will rise. However, radiative cooling will still result in low temperatures on Wednesday morning. Starting Wednesday afternoon, another small cold air mass with limited moisture will move south, increasing cloud cover in the north and bringing brief, localized showers to the north coast and eastern Taiwan. Temperatures will drop slightly.
Thursday (February 12th) will see improvements across the island with sunny to partly cloudy skies and rising temperatures. There will still be a chance of occasional, localized showers in the east. From Friday through the “Little New Year” (February 13th-15th), conditions will be clear and stable with warming temperatures, resembling spring-like weather. However, be mindful of significant day-night temperature differences due to radiative cooling.
The latest model simulations indicate that the northeast monsoon will strengthen slightly on “Lunar New Year’s Eve” (February 16th), bringing localized, brief showers to Greater Taipei and northeastern Taiwan. Temperatures will drop slightly, but other regions will experience mild, sunny to partly cloudy conditions. “Lunar New Year’s Day” (February 17th) will be clear and stable with warming temperatures and significant day-night temperature differences. There is a chance of scattered showers in the east. Beyond “Lunar New Year’s Day” (February 18th), models diverge, requiring continued observation and adjustments.
