What is Khao Phansa and how does it affect travellers?

Khao Phansa marks the beginning of Buddhist Lent (Vassa), a three-month retreat period for monks. For travellers, the main practical impact is that some Thai festivals are subdued during Lent, certain entertainment venues may have restricted hours, and traditional Thai weddings are rarely held during this period. The candle-carving festivals in Ubon Ratchathani are a major highlight tied to Khao Phansa.

Is July busy in Thailand?

July sees increased tourist numbers on the Gulf coast (Koh Samui, Koh Phangan, Koh Tao) due to European and American summer holidays, even though it is technically low season for the Andaman coast. Bangkok stays busy year-round. The Andaman coast and Northern Thailand are quieter and cheaper.

Monthly Travel Guide

Thailand in July

July falls in the heart of the low season for the Andaman coast but remains a popular month due to European and American school holidays. The Gulf coast is still Thailand's best weather bet, with warm and relatively dry conditions. Northern Thailand is lush and green. Expect sporadic but intense rain on the Andaman side; the Gulf coast can start seeing some showers but generally stays manageable. Khao Phansa (Buddhist Lent) begins in July.

Ubon Ratchathani Candle Festival

July (Asanha Bucha weekend)

One of the Northeast's great events — massive intricately carved wax candles are paraded through the streets of Ubon Ratchathani. A UNESCO-recognised cultural tradition and spectacular to witness.
