Thailand’s Wind Seasons Explained – A Deep Dive into Koh Phangan’s Unique Wind Patterns
When people research wind and weather patterns in Thailand, they often find general advice that applies to the mainland or the Andaman coast. But Thailand is a country of microclimates, and nowhere is this more obvious than on Koh Phangan — a tropical island located in the Gulf of Thailand, just north of Koh Samui.
Here, the wind seasons follow their own rhythm, different from Phuket or Chiang Mai, and they dramatically shape the kitesurfing conditions, beach atmosphere, and daily life on the island. If you’re planning to kite, foil, surf, or simply visit during the windier months, understanding Koh Phangan’s three distinct wind seasons is essential.
Overview: The 3 Wind Seasons in Koh Phangan
While many travelers are familiar with monsoon patterns, Thailand’s wind seasons are more complex — especially on islands like Koh Phangan. Here’s a breakdown of how each season plays out locally:
Northeast Wind Season
- Months: Late November – January (varies)
- Wind Direction: NE / ENE
- Main Kite Spots: Chaloklum, Haad Rin
- Conditions: Cool, misty, strong wind; flat/swell mix
Southeast Wind Season
- Months: January – April
- Wind Direction: SE
- Main Kite Spots: Ban Tai, Thong Sala
- Conditions: Most stable and consistent wind; foil-friendly
Southwest Wind Season
- Months: May – September
- Wind Direction: SW
- Main Kite Spots: Ban Tai, Hin Kong, Thong Sala
- Conditions: Unpredictable; wide range of wind strengths; stormy bursts
1. Northeast Wind Season (Late November – January)
Kite Spots: Chaloklum & Haad Rin
Wind: NE / ENE (sometimes variable)
Water: Flat inside lagoon, swell on open coast for Chaloklum ; Big waves & deep water for Haad rin
The Northeast wind season is the shortest of all wind seasons on Koh Phangan. Some years it lasts just 3–4 weeks, while in stronger years it can stretch up to 2 months, typically starting in late November and fading by mid-to-late January.
This period brings cleaner air, cooler temperatures (23–27°C), and a moody, misty island atmosphere. It’s a season that kitesurfers and wind lovers enjoy for its raw, wild beauty.
- Chaloklum – Raw Beauty and Flat Water
The most iconic spot for this season is Chaloklum Bay, particularly on the west side of the pier. A natural reef creates buttery flat water — perfect for freeride and trick training. Space can be tight, though, as the lagoon fills with fishing boats and local activity, so it’s better suited for experienced riders.
- Haad Rin – Waves for the Brave
When the wind shifts NE/ENE, Haad Rin transforms into a playground for advanced riders. Clean swell, open exposure, and tropical waves — but also gusty moments when direction turns north. Timing is everything here.
2. Southeast Wind Season (January – April)
Kite Spots: Ban Tai & Thong Sala
Wind: SE (steady and consistent)
Water: High tides until mid-March, great for foiling and twin-tip sessions
The Southeast wind season is Koh Phangan’s most reliable and consistent period. From January through April, the wind generally stays between 9–14 knots on lighter days and 15–20 knots on stronger ones, creating perfect conditions for kiteboarding and foiling alike.
This is the best season to plan a kite trip if you prefer predictability — day after day of gentle, stable breeze, warm sea, and easy tides.
- Perfect for Kite Foiling and Progression
High water levels at Ban Tai and Thong Sala make this season especially good for kite foiling and beginner lessons. Even on lighter days, foilers enjoy long, smooth rides, and beginners benefit from the forgiving depth and steady wind.
Warm water, mellow vibes, and long daylight hours make this the most popular time for both schools and recreational riders.
️ 3. Southwest Wind Season (May – September)
Kite Spots: Ban Tai, Hin Kong, Thong Sala
Wind: SW (highly variable, ranging from calm to stormy)
Water: Shallow lagoons, tidal-dependent sessions
The Southwest wind season marks Phangan’s tropical summer — unpredictable, dramatic, and sometimes intense. Unlike the more consistent SE season, this one can vary dramatically within a single day:
- Morning: 4–7 knots
- Midday: 8–11 knots
- Afternoon: 12–18 knots
- During storms: 20–45 knots
This wide range makes it both thrilling and challenging. Some days you’ll experience calm, glassy mornings followed by sudden afternoon squalls that send experienced kiters racing to smaller kites.
⚡ Adrenaline & Storm Sessions
Short tropical storms create powerful bursts of wind — often peaking at 30–45 knots. These events can be anticipated using radar apps or by following updates from local kite centers.
For the Adventurous and Seasoned Riders
The SW season isn’t for those seeking stability, but it’s rich with variety and opportunity. July and August are generally the best months, offering a mix of rideable wind days and spectacular tropical skies.
! Note on Tides: Midday low tides can leave lagoons shallow, limiting kiting to early morning or late afternoon. Always check local tide charts before heading out.
Why Are Koh Phangan’s Wind Seasons So Unique?
The island’s position and surrounding landmasses create a protective “wind pocket” effect — giving it milder, more manageable conditions throughout the year.
Koh Phangan’s location in the Gulf of Thailand shields it from the heavier monsoon patterns that hit Thailand’s west coast. As a result, the wind seasons in Thailand don’t follow a uniform pattern — and this island experiences a unique, three-season rhythm.
This same dynamic applies to Koh Samui and Koh Tao, making Phangan a key reference point for understanding wind across the Gulf region.
