April is Phu Quoc's hottest month — the dry season is ending, humidity rises, and temperatures push to 34°C in the afternoon. The Gulf of Thailand is still largely calm and the beaches are beautiful, but the intense heat makes midday outdoor activity uncomfortable. Early morning and late afternoon are the best windows for beach time. The first transitional rain showers appear in late April. Sea temperatures hit their annual peak at 30°C. Vietnamese public holidays (Liberation Day on 30 April, Labour Day on 1 May) create a brief domestic surge at month's end.

Liberation Day & Labour Day
30 April–1 May30 April (Reunification/Liberation Day) and 1 May (Labour Day) are both national holidays — Vietnamese domestic tourists flood Phu Quoc for one of the year's most popular long weekends. Accommodation for this period books out weeks ahead.
travel tips
April's intense heat (34°C+) means beach time is best from 7–10 am and 4–7 pm. Avoid direct sun from 11 am–3 pm — snorkelling is still comfortable (you're in the water), but walking between beaches and attractions is punishing at midday.
The Liberation Day / Labour Day long weekend (April 30–May 1) sees Phu Quoc fill with Vietnamese domestic tourists. Book accommodation at least 4–6 weeks ahead for this window.
April is a good month to visit the pepper farms in the centre of the island and the Khai Hoan fish sauce factory — both operate year-round but are most comfortable in the early morning before the day heats up.
common questions
April is Phu Quoc's hottest month, with afternoon temperatures reaching 34°C and high humidity. It's not ideal for those sensitive to heat. However, beach conditions remain good (30°C sea, calm water), early mornings and late afternoons are perfectly comfortable, and the island's air-conditioned resorts and restaurants are entirely functional. It's hot but manageable with good time management.
Rarely in early April, occasionally in late April. The dry season officially holds through most of April, but brief afternoon showers become possible from mid-April as the transition begins. These showers are typically short (30–60 minutes) before the sky clears. Expect the first real monsoon rains from May.
Liberation Day (30 April) and Labour Day (1 May) create a 3–4 day long weekend that sends domestic Vietnamese tourists to the islands in large numbers. Phu Quoc is one of the most popular domestic holiday destinations for this period. The island has a festive, social atmosphere — but accommodation must be booked weeks ahead, and Long Beach and Sao Beach are at their most crowded.
