Thailand in November: Yi Peng Lanterns, Loi Krathong, and the Andaman Opening

November is Thailand’s turning point month. The Andaman coast’s dry season returns — Phuket, Krabi, and Ko Lanta reopen to their full blue-water potential. Yi Peng (the sky lantern festival in Chiang Mai) and Loi Krathong (the national floating lantern festival) create the most visually spectacular events in the Thai calendar. And the weather across the north improves dramatically after months of rain. November is when the country resets, and it does so memorably.

Yi Peng — Chiang Mai Sky Lantern Festival

Yi Peng (ยี่เป็ง) is Chiang Mai’s most iconic event — the release of thousands of khom loi (sky lanterns) into the night sky, coinciding with Loi Krathong’s full moon (see below). The date falls on the full moon of the 12th month of the northern Thai (Lanna) calendar — typically the full moon night of November.

What happens: When thousands of paper lanterns are released simultaneously, the sky fills with ascending lights — photographs do not capture the experience of looking up at a sky that appears to be filling with stars rising rather than falling. The mass release at organized events (sometimes at former airports or large fields near the city) is the most dramatic version. The city-wide releases from private groups throughout the night add lanterns to the sky in waves over several hours.

Organized events: Chiang Mai runs paid ticketed lantern release events (typically organized by MAC — Mae Jo area) as well as free city-wide participation. The paid events offer a coordinated simultaneous mass release; the free city atmosphere allows participation without a ticket. Most travelers attend the city events throughout the night.

Practical:

• Book Chiang Mai accommodation 3–4 months ahead for Yi Peng week — the city fills completely
• The festival date aligns with the full moon — check the exact date for the year you’re traveling (usually November)
• Lanterns are sold throughout Chiang Mai for ₿100–150 baht each
• Fire safety: hold the lantern until it’s fully inflated and rising steadily; release in open areas away from trees and power lines

Loi Krathong — National Festival

Loi Krathong falls on the full moon night of the 12th Thai lunar month — the same night as Yi Peng in the north. The krathong is a decorated float (lotus-shaped, made from banana leaves, flowers, candles, and incense) placed on a body of water.

Where it’s celebrated:

• Chiang Mai: Combines with Yi Peng — krathongs float on the Ping River and moat while sky lanterns fill the air above
• Bangkok: Chao Phraya River and the city’s klongs (canals) are covered in floating krathongs. Wat Arun by the river is particularly atmospheric.
• Sukhothai: The former capital runs one of the most elaborate Loi Krathong celebrations in Thailand — the Historical Park is decorated with thousands of lights, and the festival has been held here since the Sukhothai period
• Ayutthaya: The former capital also runs river celebrations

What it means: Loi Krathong represents floating away bad luck, grievances, and negativity of the past year. The candlelit float drifting away on the river water is a genuinely moving tradition.

Andaman Coast Reopening

The Andaman dry season returns in November:

Phuket: The southwest monsoon ends — sea conditions improve rapidly through November. By late November, the Andaman is back to the clear turquoise conditions of the dry season.

Krabi/Railay: The karst cliffs and turquoise water of Railay Beach are accessible again. Krabi in November sees early dry season visitors at prices significantly below December-March peak.

Ko Lanta: The island’s resorts and bungalows reopen after the low season — November is early dry season with good conditions and October-level pricing.

Similan Islands: The marine national park reopens November 1 for the season (closing May 15). The first liveaboard dive trips of the Similan season start immediately in November.

Ko Phi Phi: Reopening after monsoon. The Phi Phi Islands in early November before the tourist rush of December-January are among the most beautiful weeks of the year on the Andaman.

Gulf Coast Warning

While the Andaman opens, the Gulf coast (Ko Samui, Ko Phangan) is in its rainy season — the northeast monsoon brings heavy rain and rough seas to the east coast through January. November is the wrong month for Ko Samui beach holidays. Ko Tao is partially shielded and maintains reasonable diving conditions.

Chiang Mai in November

The north in November is the best it’s been since February:

• Air quality is excellent — smoke season is months away
• Temperatures are cooling — Chiang Mai nights drop to 18–22°C, cool and comfortable
• The mountains around the city are lush from rainy season but trails are drying out
• The night markets, temples, and street food culture function in ideal walking temperatures

November in Chiang Mai (outside Yi Peng week) is among the best times to visit the city for general tourism — cool, clear, uncrowded by January standards.

Budget in November

Category	Budget	Mid-range
Accommodation (Yi Peng week)	$40–$100/night	$150–$300/night
Accommodation (general Nov)	$18–$50/night	$60–$160/night
Accommodation (Andaman, early Nov)	$20–$55/night	$70–$180/night
Meals	$1–$4/meal	$9–$25/meal

Pre-peak pricing rising toward December. Yi Peng week is the exception — Chiang Mai prices spike dramatically. Outside festival week, November represents good value on the improving Andaman coast and excellent value in the north.

The Short Version

November is defined by two moments and one opening. Yi Peng in Chiang Mai on the full moon night is the most visually beautiful event in Thailand — worth planning a trip around specifically. Loi Krathong on the same night makes every waterway in Thailand a light show. And the Andaman coast’s dry season return brings Phuket, Krabi, Ko Lanta, and the Similans back to optimal condition. November is the month the country switches back to its best travel mode — come for the lanterns or come for the beach, either way the timing is excellent.
