This period sees the highest frequency of precipitation—up to 23 days in August—though individual rain showers are not always heavy.

Spring (March-April) and autumn (October-November) are comfortable transition periods with moderate temperatures and a gradual shift in rainfall patterns.

Miaoli experiences a subtropical climate with distinct yet mild seasonal temperature variations. The annual temperature range is quite moderate. The hottest month is typically July, when the average temperature reaches 27.4°C, and daily highs can climb to 29.4°C. During this time, the average minimum temperature is around 25.4°C. The coolest months are January and February, with average temperatures around 15.8°C and 16.5°C, respectively.

The summer period in Miaoli, spanning from June to August, is characterized by hot and humid weather. Average maximum temperatures during this time consistently stay between 28.3°C and 29.4°C, while nightly minimums rarely fall below 24.6°C - 25.4°C. Given the high number of rainy days, especially in June, July, and August, the summer can feel quite muggy. Conversely, winter is quite mild and comfortable. From December to February, daytime temperatures hover around 17.9°C - 19.2°C, while nighttime temperatures drop to 13.7°C - 15.4°C, providing a pleasant coolness without any real frost.

The temperature difference between day and night in Miaoli is not very significant throughout the year, usually around 4-5°C (for example, in March the difference between the average high of 21.5°C and the average low of 16.8°C is 4.7°C, and in August between 28.6°C and 24.9°C, it's 3.7°C). This means that temperatures remain relatively stable throughout the 24-hour period, without sharp drops in the evening. The spring (March-May) and autumn (September-November) months are pleasant transition periods with gradually rising or falling temperatures, creating comfortable conditions for visiting the city. Average temperatures range from 19.1°C in March to 24.7°C in May, and from 25.9°C in September to 21.2°C in November.

In Miaoli, rainfall is distributed unevenly throughout the year, resulting in distinct wet and dry periods. Given the mild climate and average monthly temperatures, precipitation here falls almost exclusively as rain; snow is not typical for this region.

The highest amount of rainfall and the greatest number of rainy days occur during the summer and early autumn months. August stands out as the wettest month, with an average of 9 mm of precipitation and up to 23 rainy days. June is also quite rainy (8 mm and 18 rainy days), as are July (6 mm and 20 rainy days) and May (6 mm and 16 rainy days). During these months, rain occurs frequently, which is typical for the wet season.

A drier period is observed from late autumn to early spring. November is the driest month of the year, with a minimum rainfall of just 1 mm and the fewest rainy days—about 8. Winter months like January and February are also characterized by low precipitation (2 mm each) and a relatively small number of rainy days (9 days each). During this time, rain is less frequent and generally less intense. Transitional months such as March, April, and October show moderate amounts of precipitation and rainy days.

When planning a trip to Miaoli, it's important to keep its subtropical climate in mind, which is warm and humid for much of the year. Average temperatures range from 15.8°C in January to 27.4°C in July. Regardless of the season, comfortable walking shoes will be your best companion for exploring the city and its surroundings. Sunscreen, a hat, and sunglasses will also come in handy, especially from late spring to early autumn when the sun is strongest.

The summer months, from May to September, are characterized by the highest temperatures (averaging 24.7°C - 27.4°C) as well as the most rainfall (6-9 mm per month) and rainy days (16-23 days per month). During this period, we recommend packing light, breathable clothing made of natural fabrics, along with a reliable umbrella or a light waterproof jacket. Quick-drying clothes can also be very useful. Winter in Miaoli (December-February) is mild, with average temperatures between 15.8°C and 17.3°C. Layering is best for this time of year: T-shirts, long-sleeved shirts, a sweater or fleece, and a light jacket, especially for evening walks or chilly mornings. Spring (March-April) and autumn (October-November) offer pleasant weather, but the layering principle still applies as temperatures can fluctuate throughout the day, and brief showers are possible even during drier periods.
