The climate in the city of Hat Yai, located in Thailand, is characterized as tropical monsoon. This means that hot and humid weather prevails here throughout the year.

Maximum daytime temperatures most often reach 30-32°C, especially in April and May, which are considered the hottest months.

Two main seasons can be distinguished in Hat Yai, determined primarily by rainfall. The relatively dry season falls in the period from February to March, when the number of rainy days and total rainfall are minimal. Starting roughly from April-May, humidity rises, and the rainy season begins. This wet period continues until the end of the year, reaching its peak in October and November, when the highest amount of precipitation falls and rainy days are most frequent.

Despite the clearly defined rainy season, the air temperature in Hat Yai remains consistently high. Tropical downpours are often intense but can be short-lived, giving way to sunny weather. Travelers planning a trip should take these climatic features into account. For those who prefer drier weather, the best time to visit would be the months from February to April. However, even in the rainy season, Hat Yai can offer its advantages, including fewer tourists and lush greenery.

The climate in Hat Yai is characterized as tropical, with high temperatures throughout the year. The average annual temperature fluctuates slightly, remaining comfortably warm or hot. The hottest months are usually April and May, when the average temperature reaches 28.7°C, and daytime highs can rise to 32.5°C (in April) and 32.2°C (in May). Nights during these months are also very warm, with average minimum temperatures around 24.8°C - 25.2°C. Even in the "coolest" months, which are considered December and January, the average temperature holds at a level of 26.0°C - 26.2°C, ensuring warm weather.

The period from March to August can be characterized as the most sultry. In March, the average maximum temperature is 31.8°C, and by April it reaches a peak of 32.5°C. Even in June, July, and August, the daytime heat persists, with average maximum values around 31.6°C - 31.7°C. Nights bring some relief but remain warm, with temperatures rarely dropping below 24.5°C - 25.2°C during these months. Humidity, typical of a tropical climate, can intensify the sensation of heat.

The so-called "cool" season, covering the months from November to February, offers more moderate but still very warm conditions. In November, the average temperature is 26.5°C, and in December and January, it drops to 26.0°C and 26.2°C respectively. Daytime highs during this period range from 28.5°C (in December) to 30.3°C (in February), while night-time lows constitute a pleasant 23.2°C - 24.0°C. Temperature fluctuations between day and night throughout the year in Hat Yai are moderate, averaging from 5°C (in November-December) to 8°C (in March), which means that nights bring some, but not drastic, cooling compared to the daytime heat.

In Hat Yai, an interesting and rather specific pattern of precipitation distribution is observed throughout the year. Although the number of days with precipitation can be significant during certain periods, the total amount of moisture falling remains comparatively low. Snow is completely uncharacteristic for this region of Thailand; all precipitation falls as rain, which, judging by the data, often presents as light drizzle or brief light rains rather than heavy downpours.

The "driest" months in Hat Yai, both in terms of total rainfall volume and the number of rainy days, are February and March. During this period, a minimal amount of precipitation falls, averaging just about 2 mm per month, while the number of days when precipitation is recorded drops to 10-12. January can also be classified as one of the drier months with a figure of about 4 mm of precipitation distributed over approximately 17 days, indicating the very light nature of this rainfall.

The period with the highest amount of precipitation and maximum frequency of rainy days falls at the end of the year – from October to December. November stands out as the "wettest" month: on average, about 15 mm of precipitation falls, while rains can occur almost daily – up to 29 days in the month. October (about 8 mm precipitation and 28 rainy days) and December (about 10 mm precipitation and 25 rainy days) are also characterized by increased humidity. Even in these peak months, considering the total amount of precipitation, rains are likely most often moderate or light, but very frequent. In the remaining months, from April to September, a high frequency of rainy days is also observed (from 19 to 26), but with a total rainfall of just 4-6 mm per month. This confirms the general trend for Hat Yai: precipitation can be a frequent occurrence, but is rarely heavy.

When planning a trip to Hat Yai, it is important to consider its warm and humid climate, typical of Thailand. The average annual temperature fluctuates within a comfortable range of 26-28°C, so the foundation of your wardrobe should be light, breathable clothing made from natural fabrics such as cotton or linen. Do not forget sunscreen with a high SPF, headwear (a hat or cap), and sunglasses for protection against the bright tropical sun. Comfortable walking shoes, for example, sandals or light trainers, will make your walks around the city as comfortable as possible.

Particular attention should be paid to precipitation. Although the amount of rainfall in millimetres might not seem very large in some months, the number of "wet days" is significant throughout almost the entire year. Especially wet periods are the months from May to November, when rains occur frequently, reaching a peak in November. Therefore, a compact umbrella or a light raincoat will become your indispensable companions. Clothing made from quick-drying materials can also prove very practical. Even in the "drier" months, from January to March, brief rains are not excluded, so having rain protection with you will not be amiss.

In general, warm clothing will not be required for a trip to Hat Yai. However, a light cardigan or stole may come in handy for protection against air conditioning in shopping centres or cafes, as well as for evening strolls if the temperature drops slightly. Do not forget insect repellent, especially if you plan to spend time in nature or outdoors in the evening. The principle of layering is applicable here more for comfort in air-conditioned rooms than for protection against the cold.
