The weather in October
What the season does to Koh Samui this month.
Worth knowing
Gulf Islands Rainy Season
The Gulf islands are on the opposite cycle to Phuket: dry from January to August, wettest from October to December, peaking in November with heavy downpours. Ferries to Koh Tao are the first to be cancelled when the north-east monsoon blows; keep a day spare.
What’s on in October
Timing a trip around these changes what you pay and what you can book.
Loy Krathongdates shift yearly
On the full moon of the twelfth lunar month, people float candle-lit krathong baskets on rivers and ponds. Sukhothai's historical park holds the oldest celebration, with light shows over the ruins; Bangkok's riverside piers get very crowded. Hotels in Sukhothai and Chiang Mai fill weeks ahead.
