Freediving in Phuket – Seasons, Conditions & Best Time to Dive

Phuket is one of the best freediving destinations in Thailand, offering warm water all year, easy access to depth, beautiful marine life, and sheltered bays perfect for training. Whether you’re a complete beginner or a certified freediver looking to improve your depth, freediving in Phuket is possible 365 days a year.

Our Approach

At our school, we have our own boat directly on the beach, giving us full flexibility to choose the best locations and departure times depending on wind, waves, and tides. With deep knowledge of every freediving spot around Phuket, we can always find safe and calm areas—even in the monsoon season.


Below is everything you need to know about freediving conditions in Phuket, including seasons, visibility, water temperature, and the best months to visit.

Hot, Dry & Sunny Season


This is the hottest and driest time of the year, with long sunny days and very little rain.

  • Long sunshine hours almost every day

  • Wind and waves mainly come from the east

  • Mornings are often windy and slightly choppy

  • Afternoons are usually calm and ideal

  • Visibility can sometimes be slightly green and less clear due to plankton growth from strong sunlight

  • Water temperature: 29–30°C


Best conditions: Afternoon sessions are typically the calmest.

Pros:

  • Very reliable sunshine

  • Ideal for first experiences and relaxed sessions

​
Cons:

  • More crowded

  • Higher prices for flights and accommodation

​
This is the best time if you want guaranteed sunshine, though not always the clearest water.

Expect more rain and changeable conditions, but also a quieter, more peaceful side of the island.

  • Wind and swell come from the west (Andaman Sea)

  • The west coast has waves and becomes the surf season

  • Many bays (including Nāma Bay) are protected and remain calm

  • Weather is variable: it can rain all day or be sunny with short evening showers

  • Water is often very clear

  • Water temperature: 30–31°C

Boat trips may occasionally be cancelled due to offshore storms.

​
A great season for travellers who prefer fewer crowds, lower prices, and Phuket at its greenest.

Why Local Knowledge Matters

Freediving conditions in Phuket vary significantly depending on location and timing.

  • One area can be rough while another is completely calm

  • The best time of day changes with the season

  • Visibility and currents differ between sites


This is why going with an experienced team and having access to a boat makes a big difference.

At Nāma Freediving, we:

  • Select the best location each day

  • Adjust timing based on conditions

  • Provide the best possible experience regardless of season
