The city of Ubon Ratchathani is located in a tropical climate zone, characterised by hot weather throughout the year. Temperatures here are consistently high, without sharp seasonal fluctuations. The main factor to consider when planning a trip is the clear division of the year into two main periods defined by rainfall: a long wet rainy season and a shorter dry season.

The dry season, which lasts approximately from November to April, is considered the most comfortable time to visit. During these months, you can expect clear skies, plenty of sunshine, and a minimal chance of precipitation. December and January are the "coolest" months, although they remain very warm. The peak heat occurs in March and April, when daytime temperatures regularly rise above 34°C, heralding the approaching monsoon.

From May to October, the region is dominated by the rainy season. This period is characterised by high humidity and frequent, sometimes daily, downpours, which are especially intense from July to September. Despite the rain, air temperatures remain high. Travelling during this time allows you to see the region's lush, green nature in all its glory and enjoy fresher air after the tropical rains.

The climate in Ubon Ratchathani is characterised by high temperatures throughout the year, which is typical for a tropical region. The hottest period falls in spring, from March to May. The peak heat arrives in April, when the average daytime temperature reaches 35.1°C, and the monthly average is 30.4°C. During this time, the heat can be quite intense, especially leading up to the rainy season when humidity begins to rise.

The coolest and driest season lasts from November to February. The "coldest" months are considered to be December and January, with an average temperature of around 24.5°C. Although daytime temperatures remain very warm, rising to 30°C, the nights bring a pleasant coolness. At this time of year, the temperature can drop below 20°C, creating a significant difference between day and night. During the rainy season, roughly from June to October, temperatures drop slightly compared to the April peak, but due to high humidity, the heat is felt constantly, and the difference between day and night readings becomes less pronounced.

The climate in Ubon Ratchathani has a distinct division into two seasons: dry and wet. The dry season lasts approximately from November to April, offering travellers sunny and clear weather. The wet season, also known as the monsoon season, covers the period from May to October, bringing frequent and heavy rainfall.

The driest months are December, January, and February, when rainfall is practically zero. During this time, rain is a rarity, with an average of only 1-3 rainy days per month. This makes the winter months the ideal time to visit the city if you prefer to avoid the rain. March and November also remain predominantly dry, although the chance of precipitation increases slightly.

The wet season begins in May and reaches its peak from July to September. During these months, rain becomes a daily occurrence. The highest amount of rainfall occurs in September, while July and August hold the record for the number of rainy days — up to 27 per month. Precipitation during this period usually comes in the form of strong but short-lived tropical downpours that bring refreshing coolness. By October, the intensity of the rains gradually decreases, preparing the region for the arrival of the dry season.

When planning a trip to Ubon Ratchathani, it is important to consider its tropical climate, which dictates the choice of clothing. It is hot here all year round, so the foundation of your wardrobe should be light and breathable clothing made from natural fabrics such as cotton and linen. Loose t-shirts, shorts, sundresses, and light trousers will be your best companions. Given the scorching sun, do not forget to pack sunscreen with a high protection factor, sunglasses, and a wide-brimmed hat or cap. Since you will likely be walking a lot while exploring local attractions, comfortable shoes — sandals or breathable trainers — are absolutely essential.

Ubon Ratchathani has two clearly defined seasons worth considering when packing your suitcase. The dry and cooler season lasts approximately from November to April. During this time, rain is unlikely, and evenings, especially in December and January, can be comfortably warm but not exhausting — a light cardigan or long-sleeved shirt might come in handy. From May to October comes the rainy season, which brings high humidity and frequent, sometimes heavy downpours. If your trip falls during this period, be sure to take a waterproof jacket or raincoat and a compact umbrella. It is also worth prioritising clothing and shoes that dry quickly.
