Is March Right for You?
Weigh the advantages and considerations before booking
Advantages
- + Post-peak season calm: Beaches like Railay and Koh Phi Phi drop to half their February crowds, giving you actual space to lay a towel without touching a stranger's flip-flop.
- + River logistics finally work again: Mekong and Chao Phraya water levels stabilize after dry-season sandbanks, so long-tail boat drivers can shoot through narrow khlongs without scraping bottom - great for floating-market day trips.
- + Mango season overlap: March is the tail-end of nam dok mai harvest. Street carts in Bang Rak grill sticky rice fresh at 6 pm and the perfume of ripe golden mango drifts across the soi like a dare.
- + Songkran countdown energy: Bangkok hostels start filling with pre-festival backpackers, which means pop-up water-gun repair stalls, neon super-soaker sales on Khao San, and a contagious buzz you can feel in the BTS air-con.
Considerations
- − Heat that punches through SPF: Mid-afternoon concrete in Ayutthaya radiates 104°F (40°C) and shade is scarce around the ruins - plan temple circuits for dawn or risk wilting like the bougainvillea.
- − Chiang Mai haze build-up: Slash-and-burn fires in Myanmar and northern provinces thicken from early March; Doi Suthep views can drop to sepia 2 km (1.2 mile) visibility and the air smells like a campfire you overnighted in.
- − Island power cuts: Remote Andaman islands still run on generators. When afternoon humidity hits 80 % the load often trips, meaning your fan dies precisely when the sweat starts pooling behind your knees.
Best Activities in March
Top things to do during your visit
Damnoen Saduak Floating-Marketer Long-tail Trips
March water is high enough to glide the full 32 km (20 mile) canal loop without bottoming out, and morning temps sit at 26°C (79°F) before the heat spikes. You'll smell diesel mingling with pandan dumplings steaming on tiny boats while school kids in straw hats paddle past holding iced coffee bags.
Booking Tip: Book 2-3 days ahead for dawn departures (6 am) to beat the tour-bus flotilla that arrives at 9; licensed boats carry life-jackets and leave from Tha Kha pier, not the tourist parking lot.
Similan Islands Live-aboard Snorkel Safaris
Park re-opens 15 Oct-15 May; March seas average 29°C (84°F) with 20 m (65 ft) visibility, whale-shark sightings peak, and day-tripper numbers are 30 % lower than Christmas. The water is so clear you can count the chromis fish from the deck.
Booking Tip: Overnight boats fill first - reserve 10-14 days out. Verify operator is National-Park-licensed and carries reef-safe sunscreen on board.
Bangkok Night-Cycle & Temple River Crossing
7 pm start means 30°C (86°F) instead of 36°C (97°F) daytime, and the Chao Phraya breeze moves. Cross by cable ferry to Wat Arun, ride empty riverside lanes, finish with nam prik khai at a 40-year shophouse in Thonburi - open only after dark when the owners finish their day jobs.
Booking Tip: Small-group tours (max 8) provide helmets and ferry tokens. Look for routes that include Bang Luang artist house for puppet show.
Koh Yao Noi Sea-Kayak & Mangrove Tunnel Routes
Tides in March are mid-range, letting kayaks slip into mangrove tunnels without scraping mud. The water mirrors limestone karsts like glass, hornbills flap overhead, and you'll hear the hollow knock of fiddler crabs on prop roots.
Booking Tip: Start 8 am before wind chops the bay. Double kayaks more stable for first-timers. Check operator includes dry-bags for phones.
Chiang Mai Monk-chat & Alms-giving at Wat Suan Dok
March evenings are still cool enough to sit outdoors; orange-robed university monks practice English 5-7 pm on the teak terrace and invite travelers to join next-morning alms. Conversation covers everything from AI to karma while bats swoop overhead.
Booking Tip: No booking needed. But arrive ten minutes early to secure floor cushion. Bring small-denomination snacks (crisps or instant noodles) rather than sweets monks can't eat after noon.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
Book domestic flights before 10 am; March thermals build cumulons that delay afternoon departures out of Phuket and Samui.
7-Eleven iced coffee in a bag ('kafe yen') costs less than hot espresso in Europe and doubles as ice pack for pulse points.
Ask for 'roti mai wan' if you don't want sugar in Thai iced tea - default syrup load is three tablespoons.
In Bangkok, board BTS rear car. Doors align with escalator exit at Siam, shaving 90 seconds in 34°C (93°F) platform heat.
Carry small notes for highway toilets - attendants hand you exact change of two sheets. No tip needed but they appreciate 5 baht coin.
Avoid These Mistakes
Scheduling temple climbs at 1 pm: shade is minimal, stone steps reach 50°C (122°F) and flip-flops melt. Dawn or sunset only.
Assuming islands share Bangkok weather: Andaman side can be 3°C (5°F) hotter plus salt wind - pack separate lotion or skin cracks.
Booking overnight buses to save a night's hotel: March AC is arctic, drivers blast 18°C (64°F) and you'll shiver in shorts.
