As a transitional month between the dry and monsoon seasons in Bangkok, May is characterized by high temperatures and rising humidity. We'll give you an overview of the temperatures and rainfall in May, appropriate clothing, and the best activities.
Bangkok's weather and climate in May
In May, Bangkok transitions from the dry season to the monsoon season, leading to high temperatures and increased humidity, especially in the middle of the month. With daytime temperatures reaching up to 40°C, outdoor activities during the sweltering midday heat can be very strenuous. Sunscreen is strongly recommended in most parts of Bangkok to protect against the intense sun.
May marks the beginning of the rainy season in Bangkok, bringing more frequent afternoon thunderstorms and showers. The city experiences approximately 17 rainy days, concentrated mainly in the second half of the month. Despite the regular afternoon showers, the downpours are generally short, allowing you to continue your outdoor activities largely uninterrupted.
Is May a good time to travel to Bangkok?
May can be a challenging time to visit Bangkok, as the city experiences hot and humid weather during the transition to the rainy season. It is advisable to be prepared for high temperatures, high humidity, and frequent rain showers.
Despite the weather-related challenges, May offers the advantage of fewer visitors and potentially lower prices for accommodation and flights, making it a quieter and more budget-friendly time to visit Bangkok. If you don't mind the heat and occasional rain showers, you can still experience the city in a more relaxed atmosphere.
What to wear in Bangkok in May
Since it's hot and humid in the city in May, just before the start of the rainy season, it's advisable to pack loose-fitting and breathable clothing such as cotton shorts, skirts, and linen shirts to stay cool and comfortable. It's also wise to bring long-sleeved tops or several layers of clothing for air-conditioned rooms.
With the rainy season beginning, it's advisable to carry an umbrella or raincoat to be prepared for sudden downpours. Don't forget sun protection such as a hat, sunglasses, and sunscreen to protect yourself from the intense sun while outdoors.
When visiting temples or cultural sites, it is essential to dress respectfully by wearing modest clothing that covers the shoulders and knees.
The best things to do in Bangkok in May
1. Visit the most beautiful temple – Wat Arun
Wat Arun, also known as the Temple of Dawn, is an absolute must-see for anyone interested in Thailand's rich cultural heritage. Its intricate decorations and breathtaking sunsets attract numerous photographers.
Explore the prangs (towers) up close, with the central prang, adorned with thousands of colorful pieces of Chinese porcelain, being a particular highlight. Climb the steep steps to reach the top and enjoy breathtaking views of the Chao Phraya River and the cityscape beyond.
For a more relaxed experience and a great view, a longtail boat ride is recommended to experience the temple from the water from a unique perspective, especially during the atmospheric sunset. Enjoying a drink and a meal at sunset near Wat Pho Pier is a wonderful way to savor the temple's beauty.
2. Visit the Grand Palace and Wat Phra Kaew.
The Grand Palace and Wat Phra Kaew (the Temple of the Emerald Buddha) are known for their breathtaking architecture, elaborate decorations and rich history, and are among the must-see sights when visiting Bangkok.
The Grand Palace, which continues to serve as the royal residence, is a fusion of Thai, European, and Buddhist influences in its intricate details, colorful murals, golden stupas, and iconic jade emerald Buddha statue.
Please note that some architectural elements in the Grand Palace are not accessible to visitors. It is recommended to explore the palace with a private guide who can provide interesting and insightful perspectives.
Since there is little shade and the heat is intense in May, a visit in the early morning or late afternoon is recommended. To escape the heat and the crowds, a trip to the nearby hidden gem, the Queen Sirikit Museum of Textiles, is a great option.
Don't miss the Khon performances (a masked dance drama) taking place in the Sala Chalermkrung Royal Theatre at 1:30 pm, 2:30 pm, and 4:30 pm. Admission is free as part of your visit to the Grand Palace.
3. Experience lively floating markets and a railway market
A trip to Bangkok is incomplete without a visit to its vibrant floating markets. To make the most of your time, it's recommended to combine the Damnoen Saduak floating market and the Maeklong railway market into a half-day excursion.
Despite its popularity and commercialization, the Damnoen Saduak floating market still offers a vibrant and traditional market experience. A ride on a longboat is an absolute must. To avoid the exhaust fumes from motorboats during peak hours, an early morning visit is recommended.
A train ride through the Maeklong Railway Market allows you to witness how traders swiftly retract their awnings and goods as the train approaches – an impressive example of coordination and efficiency.
To fully experience the vibrant morning atmosphere, it's recommended to set off early, as the market is 1.5 to 2 hours from Bangkok. With only four trains running daily (departing at approximately 6:20 a.m., 9:00 a.m., 11:30 a.m., and 3:30 p.m.), an early start is advisable.
4. Visit Bangkok's top museum: the Jim Thompson House
If you want to escape the daytime heat in May and are interested in Bangkok's art, history, architecture and craftsmanship, then the Jim Thompson House is the place for you.
Experience the rich heritage of Thai silk through demonstrations of silk weaving and dyeing. Enjoy the peace and tranquility of traditional Thai architecture with its teakwood buildings nestled amidst lush gardens.
Discover Jim Thompson's dedication to preserving Thai culture with a stroll through rooms adorned with exquisite pieces and antiques. A private, local guide will provide insights into the history of the house and Jim Thompson's pivotal role in Thailand's silk industry.
5. Enjoy Bangkok's street food in Chinatown
If you are a foodie looking for a culinary adventure without spending too much money, then Chinatown is the place for you.
Chinatown, one of the city's most famous districts, is renowned for its vibrant nightlife and diverse street food scene. Immerse yourself in this culinary paradise and savor sizzling meat skewers, delicious noodles, and treats like mango sticky rice along Yaowarat Road.
Although finding your way around the busy streets can be a challenge due to the crowds, a local guide like ours can greatly enhance your experience.
Please note that Bangkok's Chinatown comes alive at night, offering a vibrant experience. There may not be as much to see during the day. Also, it's important to know that food stalls are open from Tuesday to Sunday, as Bangkok's streets are cleaned on Mondays.
6. Visit the National Museum in Bangkok
To escape Bangkok's daytime heat in May, a visit to the National Museum of Bangkok, the largest of its kind in Southeast Asia, is highly recommended. The museum houses a wealth of antiquities, including prehistoric art, murals, bronzes, exhibits from other Asian countries, and ceremonial carriages used by royal families.
To gain a deeper insight into the treasures on display, it is recommended to visit the exhibition with a knowledgeable guide who can provide you with historical context and deepen your understanding of the exhibits.
The National Museum in Bangkok regularly hosts special exhibitions and cultural events that offer valuable insights into Thailand's history and traditions. Check for current or upcoming exhibitions during your visit.
To fully explore the museum's galleries and exhibits, you should plan at least half a day to make the most of your visit.
