Best times for best Thailand beaches

The Andaman Coast home to pearls like Phuket and Krabi is at its peak from November to April. During these months, the weather is dry, the sea is calm, and the water is crystal clear, making it the ultimate destination for a winter beach holiday in Thailand.

The Gulf of Thailand, conversely, shines brightest from January to August, featuring gems like Koh Samui and Koh Phangan. Therefore this region is definitely ideal for a summer vacation or school break in Thailand.

The Andaman Coast: The most scenic beaches in Thailand

1. Ao Yai, Koh Phayam (Ranong)

Located near the border with Myanmar, Koh Phayam is a haven for a “digital detox.” Ao Yai Beach, stretching nearly 2 km, offers fine sand, calm waters, and an atmosphere almost entirely void of motor vehicles. It is the perfect place to disconnect from the frantic world, practice yoga, or simply admire the fiery sunsets over the sea.

2. Koh Tarutao (Satun)

Part of the eponymous National Park, Koh Tarutao is incredibly pristine, a rare example of wild Thailand. It is a destination for true nature and adventure lovers, offering camping, trekking, jungle cycling, or kayaking through mangroves.

3. Railay West & Phra Nang Beach (Krabi)

Although technically on the Krabi mainland, Railay West and Phra Nang are cut off from the rest of the world by lush jungles and towering limestone cliffs. The only way to reach them is by sea, involving a charming 15-minute long-tail boat ride from Ao Nang. Railay West is ideal for swimming and sunset watching, while Phra Nang is famous for its mystical caves, including the legendary Princess Cave.

4. Koh Kradan (Trang)

Known as Thailand’s “Crystal Island,” Koh Kradan boasts waters so transparent you can see the seabed from the surface. It is a renowned spot for snorkeling, with a vibrant coral reef accessible directly from the shore, warm waters, and powdery white sand. It is an ideal retreat for couples or those seeking absolute relaxation in a tranquil setting.

5. Long Beach, Koh Lanta (Krabi)

Long Beach is Koh Lanta’s most famous stretch, over 3 km of golden sand, calm waters, and spectacular sunsets. The vibe here is relaxed, informal, and welcoming, making it perfect for families or digital nomads. In the evening, the beach lights up with small bars, soft music, and BBQs right on the sand.

6. Bamboo Island (Phi Phi Archipelago)

Bamboo Island is a tiny, pristine gem just 5 km from Phi Phi Islands. Here, the water is a blinding turquoise, and the sand is incredibly fine, devoid of crowded resorts. It is the perfect spot for a day trip to swim, take photos, or snorkel in a natural aquarium.

7. Kata Noi and Nai Harn (Phuket)

Despite Phuket’s vibrant and sometimes chaotic energy, Kata Noi and Nai Harn beaches retain surprising tranquility. Both offer crystal-clear water, fine sand, and gentle waves, ideal for swimming, kayaking, or light surfing during the monsoon season. They are excellent choices for families and couples seeking a balance between comfort and natural beauty.

8. Freedom Beach (Phuket)

Just a few minutes by boat from lively Patong, Freedom Beach is a hidden bay surrounded by green hills, offering a sense of mystery and seclusion. Accessible almost exclusively by sea, this beach enchants with its white sand and turquoise waters, perfect for those seeking a private space to swim away from the crowds.

9. Sunset Beach, Koh Lipe (Satun)

As the name suggests, Sunset Beach (Haad Pramong) is the best spot to watch the sunset on Koh Lipe, often called the “Maldives of Thailand.” Located on the west side, this beach offers calm waters and a gentle breeze, ideal for kayaking or enjoying fresh grilled seafood at local beach shacks while the sun dips into the Andaman Sea.

10. Koh Yao Yai and Koh Yao Noi (Phang Nga)

Between the giants of Phuket and Krabi lies the majestic Phang Nga Bay, a surreal landscape of limestone karsts (like James Bond Island) and floating villages. A short distance away, Koh Yao Noi and Koh Yao Yai are oases of peace. Koh Yao Noi charms with quiet villages and yoga retreats, while Koh Yao Yai offers luxury eco-resorts far from the hustle. This is the ideal experience for those seeking tranquility and nature.

The Gulf of Thailand: Emerald paradises for your summer break

11. White Sand Beach, Koh Chang (Trat)

White Sand Beach (Haad Sai Khao) is the most popular beach on Koh Chang, a lush island reachable in about 5-6 hours by car and ferry from Bangkok. Its gently sloping seabed, rows of coconut palms, and family-friendly resorts make it a perfect destination for those traveling with children.

12. Klong Chao, Koh Kood (Trat)

Koh Kood, near the Cambodian border, is known as the “sleeping paradise.” With its primordial jungle, hidden waterfalls, and beaches with crystal-clear water, it is a favorite for couples seeking a romantic getaway. Here, you can swim, dive, or explore the famous Klong Chao waterfall.

13. Bottle Beach, Koh Phangan (Surat Thani)

Hidden in the north of the island, Bottle Beach is an isolated bay, reachable only by boat (taxi boat) or a jungle trek. Its golden sand, emerald water, and incredibly quiet atmosphere make it the ideal place to read a book, swim, or simply disconnect from everything.

14. Ao Leuk and Sai Daeng, Koh Tao (Surat Thani)

Koh Tao is the ultimate paradise for sea lovers, especially for snorkeling and scuba diving. Ao Leuk and Sai Daeng are two bays with the island’s clearest water, rich coral reefs, and the frequent (and thrilling) chance to spot harmless blacktip reef sharks while swimming.

15. Koh Nang Yuan (Surat Thani)

Just 15 minutes by boat from Koh Tao, Koh Nang Yuan is a group of three small islands connected by an iconic Y-shaped white sandbar. It is one of the most photographed spots in all of Thailand beaches. Visitors can swim in its turquoise waters, snorkel, or hike to the viewpoint for a breathtaking panorama.

FAQ: Frequently Asked Questions about Thailand beaches

When is the best time for a Thailand beach holiday?

Thailand has the advantage of two coastlines with opposite seasons. The Andaman Sea (Phuket, Krabi, Koh Lipe) is at its best from November to April (perfect for a winter beach holiday in Thailand). The Gulf of Thailand (Koh Samui, Koh Phangan, Koh Tao) is ideal from January to August. This means you can plan a splendid beach vacation almost any time of year by simply choosing the right coast.

Do I need a visa for a tour in Thailand?

For most nationalities (including European, American, and Asian citizens), the news is great: no tourist visa is required for stays up to 60 days (visa exemption rules may vary, so always check the latest regulations). You typically just need a passport with at least 6 months validity and proof of onward travel.

Which islands in Thailand are best for families with kids?

For family travel, the best choices are beaches with comfortable infrastructure, shallow waters, and gentle waves. We recommend Phuket for its services and safety.

What about a romantic couple’s getaway in Thailand?

If you seek privacy and romance, our top picks are Koh Kood (lush nature and boutique luxury), Koh Kradan (crystal waters for snorkeling together), and Sunset Beach on Koh Lipe for the most beautiful sunsets in Thailand.

Is it possible to do “island hopping” from Phuket?

Absolutely. Phuket is an excellent base. From there, you can book day trips or multi-day tours to the Phi Phi Islands, the pristine Similan Islands (seasonally), or the Racha Islands, all perfect for snorkeling and diving.

Do I need to book trains, tours, or hotels in Thailand in advance?

It is highly recommended, especially if you are traveling during the peak season (e.g. December to February). During this time, travelers flock to the country for a winter beach holiday in Thailand, so the best accommodations and tours sell out quickly.

Can I combine Thailand beaches with cultural exploration?

Certainly. A complete Thailand tour typically combines culture and relaxation. A classic 14-15 day itinerary might start in Bangkok (palaces and temples), move to Kanchanaburi (River Kwai), head south to Hua Hin or Chumphon, and then dedicate time to the islands (Koh Tao, Samui) or the Khao Sok jungle before relaxing on the beaches of Krabi or Phuket.
