September

#9 of 12 months

Avoid

Still deep monsoon — slightly less rain than August but seas remain rough and tours suspended.

  • Prices are at their annual minimum; for those with complete weather flexibility, September offers the island at near-deserted budget levels
  • Occasional sunny windows begin to appear by late September — not reliable, but longer than July or August

#1 of 12 months

Best match

Peak season with Christmas atmosphere — great weather, festive energy, and rising prices.

  • Fully dry at 35mm with 7.5 hours of sunshine daily: Long Beach and Sao Beach are at their best and all boat tours run every day
  • Christmas and New Year create a genuinely festive atmosphere across the resort strip — beach clubs, seafood restaurants, and the Duong Dong night market are at their liveliest

September trade-offs

  • 290mm of rain — still very heavy; the improvement over August is marginal and boat tours remain largely cancelled
  • Sea conditions on the Gulf of Thailand are rough and grey: Long Beach and Sao Beach offer none of their dry-season appeal
  • Most tourists who find themselves on Phu Quoc in September are there by accident or necessity, not choice

December trade-offs

  • Prices climb sharply from the second week of December — Christmas week is the most expensive period of the year
  • The island is busy: Long Beach resorts book out and flight prices from Hanoi and Ho Chi Minh City spike considerably
  • New Year's Eve crowds on the beach and resort zones are significant; the festive atmosphere is great but the quiet beach holiday is not December's strength
