Answer first: the second half of 2026 hands agents three headline sellers — Yi Peng, the sky-lantern spectacle in Chiang Mai on 24–25 November 2026; Loy Krathong, celebrated nationwide on 25 November 2026; and the Phuket Vegetarian Festival, 10–18 October 2026. Around them sits the green-to-high-season handover: the Gulf islands (Koh Samui side) are at their best through July–September while the Andaman coast sits in green season, then the whole country swings into peak from November. As a Thailand DMC for travel agents, Explera holds the calendar, the allotments and the transfers — this is the H2 2026 map to sell from. Festival dates follow the lunar calendar, so reconfirm close to travel; the trade desk keeps the live calendar.
The H2 2026 calendar at a glance
- Late July — Asahna Bucha and Khao Phansa (start of Buddhist Lent, lunar dates): temple life at its most atmospheric; alcohol sales pause on the holy days — brief clients.
- 28 July — H.M. the King's Birthday (public holiday; ceremonial Bangkok).
- 12 August — H.M. the Queen Mother's Birthday / Mother's Day (public holiday).
- 10–18 October — Phuket Vegetarian Festival: nine days of street processions, firecrackers and dedicated vegetarian street food across Phuket town — one of Asia's most photographed cultural events.
- 13 October & 23 October — memorial public holidays (King Bhumibol Memorial Day; Chulalongkorn Day).
- 24–25 November — Yi Peng in Chiang Mai: thousands of sky lanterns released over the old city and at ticketed mass-release events outside town.
- 25 November — Loy Krathong nationwide: krathong floats on rivers, canals and hotel pools from Bangkok to Sukhothai, where the festival is at its most historic.
- 5 December — Father's Day / King Bhumibol's Birthday (public holiday).
- 31 December — New Year countdowns: riverside Bangkok, beach parties across the islands, rooftop galas everywhere.
Yi Peng & Loy Krathong: the November showpiece
- What clients see — Yi Peng's mass sky-lantern releases and lantern-lit old town in Chiang Mai; Loy Krathong's candle-lit floats on every waterway in the country, the same week.
- Why it sells — it is Thailand's most photogenic week of the year and a once-in-a-lifetime hook for honeymooners, families and content-minded travellers alike.
- The catch — ticketed mass-release events, Chiang Mai hotels and domestic flights sell out months ahead; November is also the start of peak season everywhere.
- Agent move — lock space now: our Thailand DMC tours & activities team books festival tickets and guides, our hotel desk holds Chiang Mai allotments, and private transfers handle festival-night logistics when streets close.
Phuket Vegetarian Festival: the October culture hook
- What it is — nine days of Taoist devotion: white-clad devotees, shrine processions, drumming, firecrackers and famously dramatic acts of self-mortification, plus superb vegetarian street food flagged by yellow flags across town.
- Who it suits — culture-first travellers and photographers; it is intense and loud, so match it carefully.
- Why agents love it — it lands in the Andaman shoulder season, giving a strong reason to sell Phuket in October before peak pricing starts.
- Agent move — pair a guided festival morning with beach or Phuket island time; a local guide from our Thailand DMC guide services makes the rituals meaningful rather than overwhelming.
Green season to high season: what to sell when
- July–September — sell the Gulf: Koh Samui, Koh Phangan and Koh Tao enjoy their driest stretch while the Andaman is in green season; city and culture itineraries (Bangkok, Chiang Mai) run well all year.
- October — the pivot month: Vegetarian Festival in Phuket, improving Andaman weather late in the month, and the last green-season value before peak.
- November onwards — the whole country opens up: Andaman beaches at their best, festival week in the north, and peak-season demand — allotments and flights tighten fast.
- December — full high season plus festive programmes and New Year galas; book earliest of all.
How agents should plan H2 2026
- Book November first — Yi Peng/Loy Krathong week and early-peak beach stock are the scarcest inventory of the half-year.
- Use October as the value window — culture-led Phuket and late-green-season rates before the peak switch.
- Match coasts to months — Gulf for Jul–Sep, Andaman from Nov; that single rule prevents most weather complaints.
- Mind the holy days — on major Buddhist holidays alcohol sales pause and venues adjust hours; we brief itineraries accordingly.
- Lean on the DMC — the full range of Thailand DMC services for travel agents plus our source-markets desk keep festival bookings, transfers and allotments in one pair of hands; the trade desk confirms live dates and availability.
Frequently asked questions
When is Loy Krathong in 2026?
Loy Krathong falls on 25 November 2026, on the full moon of the twelfth Thai lunar month, and is celebrated nationwide. In Chiang Mai it overlaps with Yi Peng on 24–25 November. Because the date is lunar, reconfirm close to travel.
Do clients need tickets for Yi Peng?
The old-city celebrations are free to wander, but the famous mass sky-lantern releases are ticketed events outside town that sell out months in advance. We book tickets, transfers and guides as one package.
What are the Phuket Vegetarian Festival dates in 2026?
The festival runs 10–18 October 2026, during the ninth lunar month. Processions are intense — loud firecrackers and dramatic devotional acts — so it suits culture-focused clients, ideally with a guide.
Is the green season a bad time to sell Thailand?
No — it is a value window if you match the coast to the month. The Gulf islands are at their best in July–September, cities and the north run year-round, and rain typically comes in short bursts rather than washed-out days.
How early should agents book festival-week travel?
For Yi Peng/Loy Krathong week in Chiang Mai, as early as possible — hotels, event tickets and domestic flights are the half-year's scarcest inventory. December festive weeks are close behind. The trade desk can confirm current availability.
