During these months, rainfall increases significantly, and rainy days become frequent. For example, May records about 8 mm of precipitation and as many as 22 rainy days, signaling the start of the wet season.

The peak of the rainy season falls in June and August—these are the wettest months of the year. In each of these months, an average of 11 mm of precipitation falls, and the number of rainy days reaches 28. July and September are also characterized by high rainfall (8 mm) and a large number of rainy days (25 and 21, respectively). While the Hong Kong region in general is prone to monsoon downpours during the summer, the provided average data for Kowloon (e.g., 11 mm of precipitation over 28 rainy days in June or August) suggests that summer rainfall, while very frequent, typically manifests as light or moderate rain rather than constant heavy downpours.

The dry season in Kowloon sets in from November to February. During this period, precipitation is minimal. The absolute driest month is December, when there is practically no precipitation (0 mm) and only about 3 rainy days are recorded. January (1 mm, 4 rainy days) and November (2 mm, 6 rainy days) are also characterized by very low humidity levels. March and April are transitional months when rainfall and the frequency of rain gradually increase, heralding the arrival of the wet season.

When packing for Kowloon, it's important to consider its subtropical climate and distinct seasonality to ensure your luggage is as functional as possible. Regardless of the time of year, comfortable walking shoes will be your best friend, as the city is made for long walks. Layering your clothing is a great strategy for Kowloon, as the weather—especially during the transitional seasons—can be unpredictable. A light jacket or sweater will come in handy even on summer evenings in air-conditioned buildings or during cooler winter days. Don't forget sunscreen and a hat, as the sun can be quite strong even on cloudy days.

The summer months in Kowloon, from May to September, are characterized by hot and very humid weather with frequent rainfall. Average temperatures stay around 26-29°C, and the number of rainy days can reach up to 28 per month. During this period, pack light, breathable clothing made of natural fabrics (cotton, linen), shorts, t-shirts, and sandals. Be sure to bring a sturdy umbrella or a light raincoat—while rain is very frequent during this time, it is most often light or moderate. Winter, from December to February, brings a pleasant coolness (average temperature 16-18°C) and significantly less rainfall. For this time of year, jeans, long-sleeve t-shirts, sweaters, and a light jacket are suitable. While there is no frost, evening temperatures can drop to +13-14°C, so a warm layer won't hurt.

In spring (March-April) and autumn (October-November), the weather in Kowloon is at its most variable but often very comfortable, with temperatures ranging from 20°C to 25°C. This is where the aforementioned layering principle really shines: it can be as warm as summer during the day, while a light jacket or jumper might be needed in the evening. Rainfall during these periods is moderate, but it's still worth having an umbrella handy, especially in the spring months when the number of rainy days increases. In addition to clothing, don't forget a power adapter if it differs from the one used in Hong Kong, and perhaps a portable power bank for your gadgets.
