Sihanoukville

A beautiful corner of Cambodia blessed with pristine beaches and glorious scenery, Sihanoukville has recovered from the perils of its desperate past and blossomed into one of Southeast Asia’s most revered holiday destinations.

Stretching across Cambodia’s relatively small coastline, Sihanoukville has evolved from backpackers secret to a highly-regarded treasure, where the soft, golden sand of its beaches and shimmering azure waters of the Gulf of Thailand are today complemented by lavish resorts and numerous activities, including diving, fishing and spa treats.

When to Visit

Below gives you information and a rating of the best time of year to visit.

January

One of the best times to visit, January offers dry, sunny days and calm seas - ideal for beach lounging or hopping over to islands like Koh Rong. The town is lively but not overcrowded, and the air feels fresh and pleasant.

February

Continues the sweet spot of dry season. With gentle sea breezes and highs hovering around 31°C, it’s a prime time for water sports, snorkelling, or simply relaxing with seafood by the beach. Sunset views from Serendipity Beach are especially rewarding.

March

Temperatures creep up, and so does humidity. Still a great time to enjoy the coast, though early morning swims and shaded spots become more desirable. This is a good time to venture to quieter beaches or take a boat to nearby islands for peace and clear waters.

April

One of the hottest months, often reaching 32°C or above. While days can be sweltering, it’s still possible to enjoy the sea breeze and cool off with dips in the water. Expect Khmer New Year celebrations mid-month - street parties and festivities, even in this coastal town.

May

Marking the start of the wet season, May sees the occasional tropical downpour, usually in the late afternoon. Mornings remain clear, and the landscape begins to green up. It’s quieter overall, perfect for relaxed island escapes with fewer fellow travellers.

June

Rain becomes more frequent but rarely dominates the whole day. Sihanoukville feels lush and tropical, and prices drop across hotels and tours. It’s a slower-paced, more local-feeling time to visit, especially if you’re not chasing constant sunshine.

July

Wet season continues, but showers are often intense and brief. The countryside is vibrant, and boat transfers to islands may be slightly more affected by weather, but still run regularly. Pack a poncho and you’ll be rewarded with quieter beaches and moody skies.

August

One of the rainier months, yet interspersed with sunny breaks. Sihanoukville’s offshore islands remain a strong draw, offering calm beaches even on overcast days. If you’re happy with slower travel and occasional showers, this can be an atmospheric and peaceful time.

September

Often the wettest month. Some ferry crossings may be more unpredictable due to sea conditions, but the scenery is beautifully green and crowd-free. Explore the laid-back fishing village of Otres or enjoy seafood with ocean views under shelter from the rain.

October

Rain gradually tapers off, and sunny spells become longer and more reliable. Water clarity improves, especially toward month’s end - making it a good time to return to the water for diving or snorkelling. It’s a shoulder-season sweet spot.

November

Dry season kicks in again, and tourism starts picking up. The beaches regain their buzz, the islands sparkle under blue skies, and the ocean is inviting. With highs around 30°C, it’s an excellent time for kayaking, paddleboarding, or simply stretching out on the sand.

December

Arguably the best month to visit. Clear skies, calm waters, and temperatures of 30°C or so combine for a dreamy coastal escape. Festive season crowds arrive later in the month, so early December is especially blissful - perfect for relaxed, tropical downtime.
