The climate in Tam Ky can be described as tropical, with warm and humid weather throughout the year. There is practically no cold weather here in the traditional sense: even in the "coolest" winter months, such as January and December, the average temperature stays at a comfortable level above 20°C. This makes the city accessible for visits year-round, though travellers should be mindful of the high humidity characteristic of this region of Vietnam.

Throughout the year, there is a clear division between a drier, hotter season and a rainy season. From May to August, hot weather sets in across Tam Ky, with the thermometer often exceeding 30°C. This time is excellent for those who love the sun and warmth, although periodic rainfall is possible even during this period. The spring months, especially March and April, offer the most balanced conditions with moderate warmth and minimal rainfall.

A specific feature of the local climate is the pronounced wet season, which gains strength by autumn. From September to December, the number of rainy days increases sharply, reaching a peak in October when precipitation can fall almost daily. When planning a trip at the end of the year, tourists should definitely stock up on raincoats and be prepared for changeable cloudiness, which, nevertheless, lends a special atmosphere to the landscapes.

The climate in Tam Ky is distinguished by stable warmth throughout the year, which is typical for the tropical regions of Vietnam. The annual temperature graph shows no sharp spikes: even in the coolest months, which are December and January, the weather remains very mild and comfortable. The average temperature in January is about 21.9°C, and nighttime figures almost never drop below 19°C, so severe cold does not occur here.

The summer season, starting in May and lasting until August, brings real heat. The sweltering month is usually June, with an average temperature of 30.5°C and daytime highs reaching 34.4°C. During this period, the sun is very active, and nights do not bring significant coolness, as the air temperature after sunset holds at around 26°C. This time of year is suitable for those who love hot weather and plan a beach holiday.

In autumn and winter, the heat gradually recedes, making being outdoors more pleasant for long walks. In October and November, the thermometer gently drops, reaching average values of 22.3°C by December. Daily temperature fluctuations in Tam Ky are moderate: the difference between the daily maximum and nightly minimum is usually about 4–8 degrees, allowing one to easily adapt to the local climate without discomfort from sudden changes.

The nature of precipitation in Tam Ky depends directly on the season, so it is important to consider weather conditions when planning a trip. Since the city is located in a tropical climate zone, only rain falls here, and there is no snow even in the coldest months. In general, the year can be divided into periods with frequent rains and drier intervals favourable for tourism.

The wettest season falls in autumn and the beginning of winter. The peak of rainy weather is observed in October, when the maximum number of days with precipitation is recorded — about 28, as well as the highest level of fallen moisture (18 mm). From September to December, it rains almost daily, so having a reliable raincoat or umbrella is a mandatory condition for a comfortable stay in the city.

The driest period lasts from late winter to mid-spring. March and April are considered the most favourable months: the average number of rainy days decreases to 10, and precipitation levels drop to minimal values (about 2 mm). This time is ideal for long walks and excursions, as the sky remains clear more often.

The summer months occupy an intermediate position. Although the number of rainy days increases again in June, July, and August (up to 20–22 days per month), the volume of precipitation remains small (4–6 mm). This suggests that summer rains are likely short and light showers that pass quickly and bring temporary freshness on hot days.

Given the warm and humid climate of Tam Ky, the foundation of your luggage should be light clothing made from natural breathable fabrics, such as cotton or linen. From May to August, when temperatures often exceed 30°C, you will need shorts, t-shirts, and loose dresses. Be sure to bring a wide-brimmed hat and high-quality sunglasses to protect yourself from the active sun.

If your trip is planned for the period from September to January, it is worth preparing for the rainy season and slightly cooler weather. October and November see the highest amount of precipitation, so a raincoat or a sturdy umbrella will become indispensable companions. Evenings in December and January can be fresh (around 20°C), so a light windbreaker, cardigan, or hoodie will come in very handy for comfortable walks.

For exploring the city and its surroundings, choose comfortable footwear; sandals with secure straps or light sneakers are ideal. Considering the high humidity and frequent rains throughout the year, it will be useful to have a pair of shoes that dry quickly. Do not forget to pack sunscreen with a high protection factor and insect repellents, as insects can be active in the tropical climate of Vietnam.
