Find out everything about the climate and current weather in Chumphon to ensure your trip goes perfectly. Below, you will find up-to-date summaries, visual charts, and accurate forecasts for the coming days.

Chumphon welcomes travellers with a typical tropical climate, characterised by warm weather throughout the year. The temperature regime here is remarkably stable: average figures fluctuate within a comfortable range of +25°C to +28°C, remaining virtually unchanged from month to month. This makes the region an attractive destination for those who love summer and warmth, regardless of the date on the calendar.

Throughout the year, the change of seasons is clearly observed here, depending not on temperature but on rainfall. The beginning of the year, especially the period from January to April, is considered the dry season: at this time, rain is a rare phenomenon, and the sun shines brightly, warming the air to maximum values. This is the ideal time for beach holidays and sea excursions, when the sky remains clear most of the time.

From May, the weather changes, and the monsoon season arrives in Thailand, lasting until November. The number of rainy days increases significantly, reaching its peak in October. However, it is worth remembering that tropical downpours are often strong but short-lived, bringing pleasant freshness, while nature becomes particularly lush and green during this time.

Chumphon welcomes travellers with a consistently warm tropical climate, where temperature fluctuations remain insignificant throughout the year. Cold weather is practically non-existent here, making the region attractive to visit in any season. The hottest period is traditionally considered spring, especially April, when the average temperature reaches its peak of around 28.3°C, and during the day, the air warms up to 32.3°C. March and May are also characterised by high figures, creating an atmosphere of true tropical heat.

The concept of "winter" in this region of Thailand is quite relative. In the coolest months — December and January — the average temperature holds at a very comfortable mark of 25.5–25.9°C. This time is often chosen by tourists who prefer mild warmth without exhausting heat. The summer period (from June to August) is characterised by stable indicators: during the day, the thermometer usually stays in the range of 29–30°C. Although this is slightly lower than the spring peaks, high humidity in this season can intensify the sensation of heat.

During the day, a moderate temperature contrast is observed, bringing relief after a sunny day. The difference between daily maximums and nightly minimums is usually about 6–8 degrees. Even in the hottest months, nights remain warm, with temperatures around 24–25°C. In the winter period, the night temperature can drop to a pleasant 22°C, making evening walks by the sea particularly refreshing and comfortable.

In Chumphon, as in many tropical regions of Thailand, the year can be roughly divided into wet and drier seasons. Precipitation here falls exclusively in the form of rain. Analysing the statistics, one can notice that humidity begins to gradually rise in spring, leading to a prolonged period of frequent rainfall in the second half of the year.

The main rainy season lasts from May to October. During this period, tourists should be prepared for high humidity: the number of days with precipitation varies from 24 to 29 per month. The "wettest" months are September and October, when the highest volume of rainfall is recorded, and rain can occur almost daily, often in the form of intense tropical downpours.

The most favourable period in terms of weather falls at the beginning of the year. From January to March, as well as in December, the amount of precipitation becomes minimal. Although rain is possible even at this time (statistics show from 9 to 12 rainy days), it is usually short-lived and quickly replaced by the sun, making these months the best for planning a trip.

Chumphon welcomes travellers with a warm tropical climate all year round, so the basis of your wardrobe should consist of light and breathable items. Give preference to clothing made from natural fabrics, such as cotton or linen, which will help you tolerate the heat and high humidity more easily. Do not forget to bring swimwear, sunglasses, and headwear, as the sun here can be very active, especially in the dry season from January to April.

If your trip falls during the period from May to October, when the number of rainy days increases significantly, be sure to pack a light raincoat poncho or a compact umbrella in your suitcase. Footwear should be comfortable and, preferably, quick-drying; sandals with secure fastening that are not afraid of water are ideal for walking around the city and beaches. Given the frequent rainfall during these months, a waterproof case or bag (dry bag) to protect documents and electronics will be a useful accessory.

Despite the consistently high air temperature, we recommend adhering to the principle of layering and taking one light long-sleeved top or a windbreaker with you. It will come in handy during trips on heavily air-conditioned transport (buses or ferries to the islands) or on cool evenings by the sea. Also, be sure to grab sunscreen with a high SPF factor and insect repellents to ensure your holiday is as comfortable as possible.
