What to Wear in Bangkok in May

Due to the city's hot and humid weather in May as it moves toward the rainy season, it is recommended to pack loose-fitting and breathable clothing, such as cotton shorts, skirts, and linen shirts to stay cool and comfortable.

Top 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 a must-visit destination if you are interested in the rich cultural heritage of Thailand. Its intricate decorations and breathtaking sunset views attract numerous photographers.

Explore the prangs (towers) up close, with the central prang being a standout feature adorned with thousands of colorful pieces of Chinese porcelain. Climb steep steps to reach the top for a mesmerizing view of the Chao Phraya River and the cityscape beyond.

For a more leisurely experience and a great view, consider taking a longtail boat ride for a unique perspective of the temple from the water, particularly during the illuminated sunset hours. Indulging in a sunset drink and meal near Wat Pho Pier offers a delightful way to appreciate the beauty of the temple.

2. Visit the Grand Palace and Wat Phra Kaew

Renowned for their stunning architecture, intricate designs, and rich history, the Grand Palace and Wat Phra Kaew (the Temple of the Emerald Buddha) are must-visit attractions during your trip to Bangkok.

Remaining as the royal residence, the Grand Palace is a fusion of Thai, European, and Buddhist influences in its intricate details, vibrant murals, golden stupas, and the iconic Emerald Buddha statue crafted from jade.

Keep in mind that several architectural structures within the Grand Palace are not open to visitors. It is wise to explore with a private guide, who would provide you with an interesting and insightful understanding of the Grand Palace.

Due to limited shade and intense heat in May, it is advisable to visit early in the day or late in the afternoon. To escape both the heat and crowds, you may want to explore the nearby hidden gem, the Queen Sirikit Museum of Textiles.

Don't miss the Khon performances (a masked dance drama) held at the Sala Chalermkrung Royal Theatre at 1:30pm, 2:30pm, and 4:30pm, with complimentary entrance tickets included in your Grand Palace visit.

3. Experience Vibrant Floating Markets and a Railway Market

A trip to Bangkok without visiting its vibrant floating markets is not complete. To make the most of your time, it is wise to combine Damnoen Saduak Floating Market and Maeklong Railway Market in a half-day visit.

Despite its popularity and commercialization, Damnoen Saduak Floating Market still offers a lively and traditional floating market experience. Taking a longtail boat ride is a must-do activity. To avoid the fumes from motorized boats during peak hours, it's advisable to visit early in the morning.

Embarking on a train journey through Maeklong Railway Market allows you to witness vendors swiftly retracting their canopies and goods as the train approaches, showcasing impressive coordination and efficiency.

For an optimal experience in the vibrant morning atmosphere, it is recommended to start your trip early as the market is located 1½ to 2 hours away from Bangkok. With only four trains per day, departing at around 6:20am, 9am, 11:30am, and 3:30pm, getting an early start is recommended.

4. Visit Bangkok's Top Museum: Jim Thompson House

If you're seeking a cooler escape from the daytime heat in May and have an interest in Bangkok's art, history, architecture, and craftsmanship, look no further than Jim Thompson House.

Experience the rich heritage of Thai silk through demonstrations of silk weaving and dyeing processes. Find solace in the serene ambiance of traditional Thai architecture crafted from teakwood structures nestled amid lush gardens.

Learn about Jim Thompson's dedication to preserving Thai culture as you wander through rooms adorned with intricate art and antiques. A private local guide would provide insights into the house's history and Jim Thompson's pivotal role in Thailand's silk industry.

5. Enjoy Bangkok's Street Food in Chinatown

If you're a food enthusiast seeking a culinary adventure without overspending, look no further than Chinatown.

Renowned as one of the city's most iconic neighborhoods, Chinatown is known for its vibrant nightlife and diverse street food options. Immerse yourself in this culinary haven as you indulge in sizzling grilled meat skewers, delectable noodles, and delightful treats like mango sticky rice along Yaowarat Road.

While navigating the bustling streets could be somewhat challenging due to the crowds, having a local expert guide, like ours, could greatly enhance your experience.

Please remember that Bangkok's Chinatown comes alive at night, offering a vibrant experience. During the daytime, there may not be as much to see there. Additionally, it's important to note that food stalls are available from Tuesday to Sunday, as Mondays are designated for street cleaning in Bangkok.

6. Visit National Museum Bangkok

To escape the daytime heat in Bangkok in May, consider visiting National Museum Bangkok, the largest of its kind in Southeast Asia. The museum boasts a wide array of antiquities, including prehistoric art, murals, bronzes, exhibits from other Asian countries, and ceremonial carriages used by royal families.

To gain deeper insights into the treasures on display, it is advisable to visit with a knowledgeable guide, who could offer historical context and enrich your understanding of the exhibits.

National Museum Bangkok frequently hosts special exhibitions and cultural events that provide valuable insights into Thailand's history and traditions. Be sure to check for any ongoing or upcoming exhibitions during your visit.

For a comprehensive exploration of the museum's galleries and exhibits, set aside at least half a day to make the most of your visit.
