Begin a New Season and Discover the Charm of the Andaman Sea at Its Most Beautiful Time of the Year

Late rainy season and early winter is when the Andaman Sea is at its most stunning. The sky opens wide, and the ocean turns a bright turquoise, naturally blending shades of blue and green. When the gentle sea breeze drifts by, it creates an atmosphere perfect for every kind of relaxation.

This is why November to April becomes the season many people eagerly await — the only time of year when nature crafts the Andaman into its most flawless and breathtaking form. Whether you’re island hopping, snorkeling among vibrant coral reefs, or simply strolling along the beach to enjoy the sea breeze, this once-a-year beauty is a true experience you should witness for yourself.

The Similan and Surin Islands — Destinations Waiting for Your Return

The opening of the travel season for the Similan and Surin Islands in Phang Nga marks the beginning of the Andaman Sea’s High Season. Both island groups are beloved by travelers and divers from around the world for their pristine natural beauty and well-preserved ecosystems. Each year, visitors eagerly await the reopening of these islands.

Similan Islands 

The Similan Islands are one of the most spectacular diving destinations in the Andaman Sea, famous for their crystal-clear waters and vibrant marine life. The beaches here are exceptionally beautiful, featuring powdery white sand formed naturally from the erosion of coral and seashells. This unique process gives the sand an ultra-soft, bright texture that makes the coastline stand out from other islands.

Another iconic highlight is “Sail Rock,” a distinctive rock formation perched on a massive boulder, resembling a sail or a boot. It has become the symbol of the Similan Islands and a must-visit viewpoint for all travelers. With both stunning underwater scenery and pristine island landscapes, the Similan Islands are an ideal destination for diving, snorkeling, and experiencing untouched nature.

Surin Islands

The Surin Islands stand out with their serene beaches, calm turquoise waters, and peaceful atmosphere ideal for relaxation. The islands are known for having one of Thailand’s most beautiful shallow coral reefs, making them perfect for beginners and avid snorkelers alike.

The Surin Islands are also home to the Moken sea gypsies, who continue to preserve their traditional way of life. This unique cultural aspect, combined with the natural beauty of the islands, creates a destination that is rich in both ecological value and cultural charm.

5 Activities You Shouldn’t Miss During High Season

From November to April, the Andaman Sea offers bright skies and calm waters — ideal for a wide range of outdoor activities that make your holiday even more memorable.

• Snorkeling and Underwater Exploration: Clear visibility makes this the perfect time to enjoy coral reefs and marine life, suitable for both beginners and experienced divers.
• Kayaking in Phang Nga Bay: Paddle through limestone cliffs and small islands while taking in the serene natural landscapes unique to Phang Nga Bay.
• Beachfront Strolls: A simple walk along the shoreline — enjoying the sea breeze and the sound of gentle waves — is one of the most relaxing ways to unwind.
• Watching the Sunset over the Andaman Sea: Evenings are perfect for appreciating the horizon as the sun slowly sets, allowing you to enjoy the seaside atmosphere in a calm and effortless way.
• Savor Fresh, Local Seafood: Fresh seafood straight from local fishing boats is an experience you shouldn’t miss. Its naturally sweet flavor and simple preparation bring out the true charm of the Andaman Sea. From the firm, sweet meat of Andaman mackerel, to salt-grilled sea bass with its signature hint of ocean aroma, to the uniquely local sour curry made with hardtail fish, every dish reflects the richness of the sea and supports the livelihood of coastal communities.
