What that actually means for your trip:
- May is the hinge between heat and rain. The first half often still feels like the hot season, with fierce sun and heavy air; the rains usually settle in through the second half.
- The storms bring relief. A late-afternoon downpour cools the air for an hour or two, and the evening after it is the most pleasant part of the day.
- The nights stay warm. Lows of about 27°C mean little cooling after dark; air-conditioning is essential.
- The sun is close to overhead. UV is extreme in the middle of the day, so plan outdoor sights for the morning.
Is May a good time to visit Bangkok? Yes, for value and for fruit, if you can handle heat. It is low season, with some of the year's best hotel prices and quieter temples, but it is one of the hottest months, and the rains begin. Plan mornings outside and afternoons under a roof.
#The fruit month
May is the height of Thailand's fruit season.
Durian is at its peak, with the Monthong and Chanee varieties in every market; mangosteen arrives, with its thick purple skin and white segments; and rambutan, longan and the last of the mangoes fill the stalls.
The covered Or Tor Kor market by Chatuchak, open every day, is the best place to taste the best fruit in any weather, and the stalls will cut and pack a durian for you.
#The May calendar
Coronation Day, Tuesday 4 May 2027, marks the King's coronation and is a public holiday, with portraits decorated along the royal avenues.
The Royal Ploughing Ceremony at Sanam Luang, next to the Grand Palace, marks the start of the rice-growing season; its date is set each year by court astrologers and usually falls in May. Oxen choose between offerings of rice, grass, water and liquor, and their choices are read as a forecast for the harvest.
Visakha Bucha, the holiest day of the Buddhist year, marking the Buddha's birth, enlightenment and death, falls on the full moon of the sixth lunar month, in May or June. It is expected in May in 2027; the Thai Cabinet confirms the date. At dusk, people walk three times around the temples with candles, incense and flowers, the wian thian, and alcohol sales are normally banned for the day.
Bangkok Pride, held in recent years at the end of May or start of June, fills Silom and Sukhumvit with a parade; check the dates once they are announced.
#What to Do in Bangkok in May
The temples, early
Visit the Grand Palace and Wat Phra Kaew at opening time, before the heat and the tour groups; entry is THB 500 and the dress code is strict.
Wat Pho, with the great reclining Buddha, costs THB 300 and is next door; Sanam Chai MRT station brings you out beside it.
Solo Travellers
Take a longtail boat through the canals of Thonburi from a pier near the Grand Palace in the morning, when the light is good and the rain has not started.
Spend the hot afternoon at Museum Siam or the Bangkok Art and Culture Centre, which is free.
Couples
Book a Thai massage for the late afternoon, when the storm usually breaks, and a riverside table for the cooler evening. A sunset drink at a rooftop bar works on dry evenings; check the forecast first.
Families
Chatuchak Weekend Market is best in the early morning, before the heat; the plant section is lush after the first rains.
The aquarium and malls around Siam fill a hot afternoon.
Groups
Book ringside seats for Muay Thai at Rajadamnern, the oldest of Bangkok's stadiums, for a hot, loud evening indoors. On another night, eat your way down the stalls of Yaowarat, Chinatown, once the storm has passed.
#Getting Around
From Suvarnabhumi, the Airport Rail Link to Phaya Thai takes about half an hour and costs no more than THB 45; from Don Mueang, the SRT Red Line or a metered taxi.
In the city, the BTS Skytrain and the MRT are air-conditioned and run above or below the traffic, and covered walkways link many stations to the malls.
The Chao Phraya Express Boat is the way to the old town and the riverside temples, with a breeze on the water.
When the afternoon storm breaks, roads jam and flood quickly; travel by rail or wait it out with a drink rather than sitting in a taxi.
#Budget & Costs
| Travel style | Per day | What it covers |
|---|---|---|
| Budget | THB 800–1,300 | Guesthouse room, street food, public transport |
| Mid-range | THB 2,500–4,500 | 4-star hotel at low-season rates, restaurant meals |
| Luxury | THB 9,000+ | Riverside hotels with low-season offers |
May is low season, and the big hotels run their best offers of the year from now until October.
Costs worth knowing:
| What | Price |
|---|---|
| Airport Rail Link | Up to THB 45 |
| Grand Palace and Wat Phra Kaew | THB 500 |
| Wat Pho | THB 300 |
| Mangosteen at the market | Sold by the kilo, cheapest in season |
| Tourist entry fee | Proposed, not yet in force |
- A proposed 450-baht entry fee for foreign visitors has not yet been approved; check before you travel.
- Fruit is cheapest in May and June, at the peak of the season.
- Low-season hotel deals often include breakfast or upgrades.
#Food & Dining
Beyond the fruit, May menus are full of the hot-season classics: khao chae, rice in jasmine-scented iced water with sweet and salty side dishes, a royal recipe eaten in the hottest months; som tam, papaya salad; and mango sticky rice while the mangoes last.
Krua Apsorn, near the Democracy Monument, cooks the home-style Thai food Bangkok people eat; Yaowarat's street stalls set up in the evening; and the food halls in the big malls are the place for lunch on a hot day.
#Nightlife
May evenings are warm and often wet.
The cocktail bars of Sukhumvit, Thonglor and Ari carry on under a roof; Saxophone Pub near Victory Monument has live music every night; and the rooftop bars close their open decks when a storm comes in. On Visakha Bucha, expect most bars to be dry.
#Shopping
Low season is a good time for the malls: Siam Paragon, CentralWorld, ICONSIAM and Terminal 21 are air-conditioned refuges in the heat.
Chatuchak on a weekend morning has the best range of crafts, plants and vintage clothing.
In the fashion malls of Pratunam, the new summer stock is in.
#Culture & Etiquette
- Respect the monarchy; royal portraits and ceremonies are treated with great seriousness.
- At temples, cover shoulders and knees, take off your shoes in the halls, and never point your feet at a Buddha image.
- On Visakha Bucha, join the candle procession quietly, walking clockwise, and follow what local people do.
- At the Ploughing Ceremony, watch from the public areas and keep phones quiet.
- Tipping: round up in restaurants, and THB 50–100 for a good massage.

#Packing List
- Light, loose, quick-drying clothes
- A long, light layer for temples, covering shoulders and knees
- A hat, sunglasses and high-SPF sunscreen
- A compact umbrella for the afternoon storms
- Sandals that grip on wet floors
- Mosquito repellent
- Electrolyte sachets for the heat
#Backup Plans
If the heat is too much: spend the middle of the day in Museum Siam, the Jim Thompson House, a mall or a massage shop, and go back out after 4pm.
If the storm breaks while you are out: step into the nearest mall, café or 7-Eleven and wait; most May storms pass within an hour or two.
If you miss the Ploughing Ceremony: Sanam Luang is a public ground beside the Grand Palace, and the Bangkok City Pillar Shrine nearby is worth a visit on any day.
#Safety & Health
Heat is the main risk in May: drink plenty, carry electrolytes, and rest in the shade or air-conditioning in the middle of the day. Dengue is carried by mosquitoes that breed after the first rains, so use repellent, especially at dawn and dusk. Floodwater after a storm hides open drains; walk around it. Tap water is not for drinking.
Emergency: 191 for police, 1669 for an ambulance, 1155 for the English-speaking Tourist Police.

Frequently Asked Questions
Is May a good time to visit Bangkok?

When does the rainy season start in Bangkok?
Usually during May. The first half of the month often still feels like the hot season, and the rains settle in through the second half, as storms that build in the afternoon and pass in an hour or two. The wettest months come later, in September and October.
What is the Royal Ploughing Ceremony?
An ancient royal rite at Sanam Luang, beside the Grand Palace, that marks the start of the rice-planting season. Its date is set each year by court astrologers and usually falls in May. Sacred oxen choose between offerings such as rice, grass, water and liquor, and their choices are read as a forecast for the year’s harvest.
Is Bangkok cheap in May?
Hotels are, with some of the best low-season rates of the year, and the fruit markets are at their cheapest. Flights depend on where you travel from and on school holidays at home. The big hotels often add breakfast or upgrades to their rainy-season offers.
