Tan An, located in Long An Province in southern Vietnam, features a classic tropical savanna climate. This region is characterized by consistent heat throughout the year and a clear division into two distinct seasons: dry and rainy. Thanks to its proximity to the Mekong Delta, high humidity is often observed here, creating an atmosphere of eternal tropical summer.

The main feature of the local weather is its predictability. The dry season lasts approximately from November to April: this is a time of cloudless skies and minimal rainfall, when travel conditions are most favorable. The rainy season spans from May to October, bringing heavy but usually short-lived downpours and increased cloud cover, while air temperatures remain consistently high.

The city is situated in a flat area, so there are no sharp climatic fluctuations. Tourists should expect true tropical heat, which is only softened in the shade of gardens or during refreshing evening thunderstorms in the summer months.

Temperatures in Tan An remain consistently high throughout the year, mostly ranging from +22°C to +34°C. The hottest period is considered to be April and May, when daytime figures can reach +36°C. Due to high humidity during these months, the heat feels particularly intense, creating a "sauna" effect.

December and January can be called relatively "cool." During this time, daytime temperatures drop to a comfortable +30°C, and nights bring a pleasant freshness with temperatures around +23°C. Daily fluctuations here are small, usually no more than 8–10 degrees, making the climate of southern Vietnam predictable for holiday planning.

For those planning a holiday by the water, it's important to know that water temperatures in local bodies of water and coastal areas stay very warm year-round — from +25°C in winter to +29°C in the summer months. This allows for swimming at any time, although the dry season from November to April is considered the most comfortable period.

Rainfall patterns in Tan An have a pronounced seasonal character. The rainy season, occurring from May to October, is characterized by frequent and powerful downpours. The peak of humidity usually arrives in September and October, when rainfall reaches its maximum and rainy days occur almost daily. However, rain here rarely lasts all day: most often, these are vigorous afternoon thunderstorms, after which the sun comes out again.

In contrast, from November to April, dry weather sets in across the Vietnam region. February and March are considered the driest months, when rain becomes an exceptional rarity. This is the ideal time for visiting outdoor attractions, as the probability of precipitation is minimal.

The total annual rainfall is about 1500–2000 mm. Snow is completely absent in this part of the country due to consistently high temperatures, and light drizzle is practically non-existent — precipitation falls mainly in the form of intense tropical downpours that quickly fill the canals of the Mekong Delta.

When heading to Tan An during the dry season (November–April), choose clothing made from natural, breathable fabrics such as cotton or linen. You will need light shorts, T-shirts, and comfortable open shoes for long walks. Be sure to bring high-quality sunglasses and SPF 50+ sunscreen, as the sun in southern Vietnam is very intense.

For a trip during the rainy season (May–October), you should supplement your wardrobe with items made from quick-drying materials and a lightweight, compact raincoat or poncho. An umbrella will also be useful, although a waterproof cape is often more practical in tropical downpour conditions. Don't forget to pack effective insect repellents, which are especially active in high humidity.

Regardless of the season, it is always helpful to carry a reusable water bottle and a small first-aid kit with electrolytes to maintain salt balance in the heat. If you plan to visit temples, remember to bring light clothing that covers your shoulders and knees to respect local etiquette.
