Koh Lipe diving season at a glance

Dry season, November to April, is the core window. Seas are typically calm, and the Tarutao dive sites are open. Some regional guides stretch the Andaman window to October–May. Lipe's pinnacle diving fits November–April better, because the national park typically stays shut until 15 October and closes again on 15 May. Water stays warm all year, roughly 26–30°C (79–86°F).

• Best window: November–April, busiest December–February
• Park closure: typically 15 May–15 October
• Water temperature: about 26–30°C (79–86°F) all year

Month-by-month Koh Lipe diving season conditions

Use this table as a planning screen, not a forecast. Visibility in the dry months is typically quoted at 15–25 m, with 15–30 m also given. Treat that as a range that shifts by month and site.

Why the national park closure defines the season

Most pinnacle diving sits inside Tarutao National Park. Stonehenge pinnacles and 8 Mile Rock depend on park access. Adang Corner and Koh Adang's reefs follow the same rule. Park closures typically run from 15 May to 15 October. Thailand's Department of National Parks publishes the current notice, and dates can change by year. Some Tarutao sites are about 15 minutes from Lipe by speedboat, so a closure removes much of the menu. Closer sites such as Pattaya Corner and the Jabang dive site fill the gap. Ask your center which sites it is running that week. Our dive site guide for Lipe maps each option. Island-hopping circuits are affected too, so island snorkeling tours to outer islands typically pause until 15 October. Day trips toward Koh Rawi's reefs follow the same calendar.

Dry season (November–April): what to expect

From November to April, air temperatures typically run 24–32°C (75–90°F). Sea temperature sits near 28°C (82°F). Calm water and long visibility make these the easiest months for beginners and photographers. Christmas and New Year are the busiest weeks. Ferries and dive slots fill first, so book both well ahead. Compare schedules at dive centers on Lipe before fixing ferry dates. Prices below were checked November 2026. Published room rates show the swing. Air-conditioned rooms ran about ฿2,200 a night over Christmas 2018. A September 2026 guest paid ฿1,008 near Sunset Beach. Those are different properties, so read the gap as direction, not a quote. Agency tools such as the SSI dive center locator help you shortlist centers.

Shoulder months: October, November, April and May

Shoulder months trade certainty for space and lower prices. Is a late-October trip worth the gamble? Only if you can absorb cancelled boat days. Arrive after 15 October, since the park typically reopens that day. Keep spare days at the end of the trip. Seas can stay choppy until the monsoon fades, and visibility can dip at both ends of the season.

• October: park reopens 15 October, prices are low, and cancellations are likely early in the month.
• November: dry weather builds and crowds stay lighter than in December.
• April: seas are mostly calm, heat builds, and visibility can slip late in the month.
• May: the park closes 15 May, so book pinnacle dives before that date.

Wet season: can you still dive Koh Lipe?

From May to October, waves of 2–3 m have been reported, and ferries run rough. Air temperatures typically reach 28–35°C (82–95°F), with humidity up to 90%. Visibility drops, and some boat services are limited. Unlike many Andaman bases north of Phuket, Lipe shops typically keep running through the green season. Expect fewer sites and more weather cancellations. Flexible, budget, macro and house-reef divers get the best deal. Skip these months if you have fixed dates, want pinnacle trips, or get seasick easily. Non-divers can try snorkeling off Lipe, though rain and swell cut visibility there too.

Best time by diver type

Currents are site-dependent. Reports differ: one operator describes moderate to strong flow at 8 Mile Rock and Adang Corner, while a travel site calls most sites nearly current-free. Ask shops about the day's current before booking drift dives. Sightings of manta rays or whale sharks are reported at deeper pinnacles, but no month guarantees them.

Getting to Koh Lipe in diving season

Ferries and speedboats reach Lipe from Pak Bara pier in Satun province, and from Langkawi in Malaysia. Arrivals from Langkawi are processed at a small immigration office on Lipe. Hat Yai is the closest international airport, with Krabi and Phuket as other gateways. Waves of 2–3 m between May and October make crossings rough, so allow slack on both ends of a trip. Timetables change by season; check the operator before booking.

Koh Lipe vs other Thai dive regions by month

Gulf of Thailand islands run on the opposite pattern. Koh Tao, Koh Samui and Koh Phangan typically see their worst monsoon weather around November and December. June to September is generally calmer there, though July and August crowds follow European school holidays. April and May bring whale-shark chances at Gulf pinnacles such as Chumphon Pinnacle. Similan and Surin liveaboards typically operate October to May. Choose Lipe for November–April pinnacle diving, or the Gulf when the Andaman is rough.
