Thailand in May weather: What you should expect

May marks a seasonal shift in Thailand - from the scorching heat of summer to the refreshing rains of the wet season. Thailand's weather in May is characterized by average temperatures ranging from 27°C to 35°C, accompanied by high humidity. While the sun still shines brightly during the day, the skies often turn cloudy in the afternoon, bringing short but heavy downpours.

The good news? These rain showers usually don’t last long—they pass quickly and leave behind cooler, cleaner air. One of the best parts about Thailand in May weather is what comes after the rain: clear blue skies, refreshed landscapes, and beautiful natural light—perfect for photos and slow walks through nature. If you’re a fan of greenery, waterfalls, and vibrant countryside scenes, May offers just that. The forests come alive, rice fields glow in fresh green, and nature feels renewed.

Visakha Bucha Day

One of the most important Buddhist holidays in Thailand in May, Visakha Bucha Day marks the birth, enlightenment, and passing of the Buddha. Temples across the country hold candlelight processions, where people walk in silence with flowers, incense, and candles. From the vibrant streets of Bangkok to the calm temples of Chiang Mai, this spiritual tradition offers a peaceful and memorable cultural experience.

Royal Ploughing Ceremony

Dress appropriately

Thailand in May can be hot and humid, so wear light and breathable clothes to stay cool. When visiting temples or sacred sites, dress modestly—cover your shoulders and knees. Some temples provide scarves or sarongs for rent if needed.

Getting around Thailand

Getting around Thailand is easy, even in May. Here are some common and convenient ways to travel:

• Taxis: always ask the driver to use the meter or agree on a fare before the ride.

Currency exchange and payments

Thailand’s currency is the Thai Baht (THB). While many hotels and big restaurants accept credit cards, small shops and street food stalls usually take cash only. It’s a good idea to exchange some baht in advance or withdraw from ATMs after arrival. Exchange booths in town usually offer better rates than at the airport.

Respect local culture

Thai culture values politeness and respect. Following these customs will help you enjoy a more meaningful and respectful Thailand travel experience.

• A common greeting is the “wai”—placing your palms together and bowing slightly.

• Always take off your shoes before entering temples or homes.

• Avoid touching Buddha statues and don’t use your feet to point at people or objects.
