May is high for Phu Quoc.
May is the transition month — first half (May 1-14) still mostly dry with moderate pricing; second half brings the southwest monsoon onset and daily afternoon thunderstorms. An Thoi snorkel tours run with 70-80% reliability post-May 15 (cancellations on rough-sea days). Korean Golden Week (Apr 30-May 5) overlaps the start and drives a regional spike from Seoul + Busan.
Pattern after May 15: clear mornings (7-13:00) → afternoon thunderstorms (14-17:00) → clearing evenings. Schedule Hon Thom + Sao Beach morning departures, indoor activities (Vinpearl Safari covered zones, spa, Duong Dong cafes) in afternoons, sunset dinners at Long Beach.

May Weather at a Glance
May averages 90°F / 32°C highs and 79°F / 26°C lows with 14 rainy days and 200mm rainfall — rainy days double from April. Humidity climbs to 80%. UV 11 (sun still strong between storms). Sea 29°C very warm. Sunshine drops to 7 hours. First half of month still mostly dry; second half brings true monsoon pattern.
May Travel Advice
Korean Golden Week (Apr 30-May 5) book early — Korean tourist demand spikes. Pre-book Hon Thom early-morning departures (8:30-10:00) — afternoon tours cancellation-prone. An Thoi snorkel: book first-half-of-month trips 2+ weeks ahead. May 16-31 = year's best mid-range hotel value. Travel insurance with cancellation coverage recommended for second-half-of-month stays.
Flying In from Overseas
Korean Golden Week + Japan Golden Week drive heavy regional inbound first week. Post-May 7: arrivals drop sharply (regional vacationers know to avoid monsoon). Direct flights from Seoul $300-500, Bangkok $130-280, Singapore $180-350. Indian wedding-season inbound brief peak. Australian autumn shoulder.
May Pricing Trends
Korean Golden Week + monsoon split: Long Beach 4-star $80-180/night first week, $50-120 post-May 15. Sao Beach mid-range $70-160. JW Marriott Emerald Bay $400-1,100 first week, $300-700 late month. Hon Thom cable car $25-32. Year's most affordable mid-range stays start mid-May.
