Sea of Thailand, we can travel in all seasons. In the winter like this, we see many people only go to travel to the mountains but we see a lot of people and feel chaotic, so we want to go on a relaxing trip. If so it is like this, we should go to the sea, do we? Because of the Thai sea, we can travel in every season and travel to the sea in winter may get a different atmosphere from the summertime. But there is any sea that is suitable to visit during a time like this or not. Let’s have a look!

Sea of Thailand, we can travel in all seasons

🏝️ Koh Kood, Trat Province — palm beaches & Khlong Chao Waterfall

Blessed with glassy coves and a low-key pace, Koh Kood shines in the November–April dry season (peak Nov–Feb; shoulder months can still be lovely, and some years run fine into May). Inland, Khlong Chao Waterfall—a three-tier fall with water year-round—sits near the main beach, while the island’s forest hides the colossal Makayuk “Giant Tree” and the shady cascade of Huang Nam Khiao (Keaw) Waterfall. Hikers seek the rock prow of Khao Rearub (Battleship Mountain), and on the east coast, Ban Ao Yai offers a photogenic stilt village over a quiet bay. Note that off-season boats may be limited, so plan transfers around the weather. Bring reef-safe sun care, ride carefully on village roads, and leave no trace so the island’s waters stay crystal clear.

🏝️ Koh Samed, Rayong Province — white sand & clear water.

Close to Bangkok yet pleasantly unhurried, Koh Samet blends pale sand, aquamarine water, and a choose-your-vibe coastline. Set within Khao Laem Ya–Mu Ko Samet National Park, it pairs quiet coves with livelier beaches lined with cafés, bars, and laid-back resorts. Days drift by swimming and snorkeling over coral patches, renting kayaks/SUPs, or cruising to viewpoints for golden-hour color; west-facing bays deliver dreamy sunsets. Nights turn sociable—think squid-fishing outings, casual seafood grills, and signature fire shows that paint the shoreline with sparks. Weekends can be busy, so book ahead; carry some cash for stalls, use reef-safe sun care, and follow park rules so Samet’s waters stay crystal clear.

🏝️ Koh Chang, Trat Province — long beaches & Klong Plu Waterfall.

Thailand’s second-largest island, Koh Chang shines in the October–April dry season when seas are calmer and the water turns postcard-clear. On the west side, beaches such as Klong Prao and Kai Bae mix family-friendly stretches with cafés and bars, while the east offers mangroves, fishing hamlets, and hideaway resorts. Offshore reefs inside Mu Ko Chang National Park make easy snorkeling day trips, and after dark many boats run fun squid-fishing outings. Expect jungle-backed bays, waterfall hikes, and sunset viewpoints. Tips: book weekends/holidays early, drive carefully on steep island roads, use reef-safe sunscreen, and pack out your trash so the reefs stay healthy.

🏖️ Pattaya, Chonburi Province — beach city & Koh Larn day trips.

Close to Bangkok and easy to reach, Pattaya delivers a choose-your-own-adventure seaside getaway. Relax on city sands or head to nearby Koh Lan (Koh Larn) for swimming and boat trips in clearer water. Off the beach, the city packs in viewpoints, museums, a floating market, photogenic cafés, and family attractions—from a sheep farm to a chilled ice city experience—so groups with different interests can still travel together. Stay one night or several; hotels range from chic beachfront resorts to wallet-friendly guesthouses. Evenings bring street food, seafood restaurants, and a famously lively nightlife. Tips: book boat times to Koh Lan early on weekends, use reef-safe sunscreen, and consider Jomtien or Wong Amat for a quieter shoreline.

🏝️ Koh Samui, Surat Thani Province — beaches & Ang Thong trips.

Thailand’s third-largest island, Koh Samui charms with a choose-your-vibe coastline and a green interior. The east side—Chaweng and Lamai—offers water sports and nightlife; the north and northwest—Bophut (Fisherman’s Village), Maenam, Bang Por—lean relaxed and family-friendly, while the west—Lipa Noi and Taling Ngam—delivers mellow sunsets. Inland, hike to Na Muang 1 and 2, wander the Secret Buddha Garden, and pause at Lad Koh viewpoint. Culture stands out at Wat Phra Yai (Big Buddha) and Wat Plai Laem. Offshore, kayak or snorkel the lagoons of Ang Thong National Marine Park; day trips reach Koh Phangan or, with a longer ride, Koh Tao. Expect beach clubs and night markets alongside yoga, spas, and cooking classes—Samui balances energy with ease.

🏝️ Surin Islands, Phang Nga Province — pristine reefs & quiet bays.

Set off Phang Nga’s coast, the Surin Islands deliver some of Thailand’s best shallow reefs for snorkeling—think glassy lagoons, turtle and anemone gardens, and sandy, crab-scattered beaches. Boat trips loop quiet bays and, for divers, nearby Richelieu Rock rises from deep water as a horseshoe reef famed for purple corals and seasonal pelagics. Ashore, short nature paths weave through coastal forest to calm viewpoints. The islands are also home to a Moken community; visit with licensed guides, ask before taking photos, and purchase local crafts to support livelihoods. Note the marine park’s seasonal rhythm: it typically opens roughly mid-October/November through mid-May and closes during the monsoon to protect visitors and let reefs rest. Pack reef-safe sun care, plenty of water, and carry out all trash.

🤿 Koh Tao, Surat Thani Province — top diving & Shark Bay snorkel.

Ringed by reefy coves and granite headlands, Koh Tao mixes easy beach time with standout underwater life. Visibility is often best February–April, and conditions are usually gentle for learning to dive. Classic sites like Chumphon Pinnacle and Southwest serve turtles, schooling fish, and seasonal pelagics, while calm bays suit snorkelers. On land, rent a scooter (ride carefully) to viewpoints such as John-Suwan or Love Koh Tao, pause for sunset at Sairee, and detour to the sandbar and viewpoint on Koh Nang Yuan. Off-beach options include kayaking, paddleboarding, fishing trips, and short jungle walks to hidden coves. Evenings lean relaxed: night markets, beach grills, and low-key bars. Use reef-safe sun care, avoid touching coral, and pack out trash so the water stays glass-clear.

🏝️ Koh Lanta, Krabi Province — sunset beaches & Koh Rok snorkel.

Spread across Lanta Yai and Lanta Noi, Koh Lanta pairs spacious sands (Klong Dao, Phra Ae/Long Beach, Kantiang Bay) with calm water—especially Oct–Apr. Nature is close at hand: snorkel the reefs of Koh Rok/Koh Haa, hike to Khlong Chak Waterfall, and paddle mangroves at Tung Yee Peng. Inland, headlamps lead you through Khao Mai Kaew Cave, while the lighthouse headland inside Mu Ko Lanta National Park serves up big sea views and breezy picnics. Lanta Old Town adds teak-house charm and easy seafood stops. Plan unhurried days—swims, short trails, island runs—and unroll evenings with sunset, markets, and low-key bars. Pack reef-safe sun care and plenty of water; the island’s rhythm rewards slow travel.
