A peaceful riverside retreat in Bangkok, The Siam combines heritage design with thoughtful, contemporary comfort.
Location
Perched on the banks of the Chao Phraya River, The Siam offers a peaceful retreat right in the heart of Bangkok. We love how this refined urban hideaway balances complete tranquillity with easy access to the city’s cultural treasures—Wat Arun and the Grand Palace are just a short boat ride away, yet the hotel feels miles from the buzz. With its private pier, riverside charm, and leafy courtyards, The Siam is perfectly placed for a stylish, serene escape.
Rooms
With just 39 suites and villas, The Siam is beautifully intimate. Each room is a masterpiece—Art Deco elegance layered with Thai antiques, silk furnishings, and thoughtful details. We love the oversized bathrooms, towering ceilings, and the personal butler service that comes as standard. Riverfront Pool Villas add even more luxury, with private pools and sun decks looking out over the water. Every space feels like a private sanctuary.
Wellness
The Opium Spa (formerly Asaya) is one of Bangkok’s best-kept secrets. Tucked away in a tranquil garden setting, it offers a carefully curated menu of therapies—from traditional Thai massage to bespoke wellness programs designed around your needs. You’ll also find a fully equipped gym, yoga and meditation spaces, and a riverside Muay Thai ring if you fancy something a little different. It’s the kind of place that nurtures mind and body in equal measure.
Dining
Dining at The Siam is a feast for the senses. Chon Thai serves classic Thai flavours with flair in a series of century-old teak houses, while the riverside Deco Bar & Bistro offers a more relaxed menu with international favourites. We especially love the sunset views from the pier, cocktail in hand. Ingredients are locally sourced, and menus change with the seasons to keep things fresh.
Activities
From private longtail boat cruises to Thai cooking classes, there’s always something meaningful to experience here. Art lovers can tour the hotel’s exceptional private collection, while those looking to unwind can lounge by the serene infinity pool or browse the curated library. The team is always on hand to help personalise your stay—whether you want to dive deep into the city’s heritage or simply relax in style.
Sustainability
The Siam blends elegance with environmental care. The property is built using sustainable materials and operates with a strong focus on energy efficiency and waste reduction. Eco-friendly amenities and water-saving systems are seamlessly integrated, while the hotel supports community-based initiatives across Bangkok. It’s luxury with a conscience—and we’re all for it.

January
January is one of the best months to visit Thailand, with dry, sunny days and cooler temperatures across most of the country. It's an ideal time for beach holidays in Phuket, Krabi, and Koh Lanta, where the sea is calm and crystal clear. In the north, Chiang Mai and Chiang Rai offer crisp mornings and pleasant days, perfect for exploring temples and mountain landscapes. It’s also peak tourist season, so book in advance for popular spots.
February
February continues the dry season with reliably sunny weather and temperatures starting to climb. Beach conditions are still fantastic, especially on the Andaman coast. It’s also a great month for visiting Bangkok and central Thailand, where humidity remains relatively low. Festivals like Chiang Mai’s Flower Festival add extra colour to the month, and hiking in the north is still very comfortable.
March
March marks the start of the hot season, with rising temperatures across the country. It’s a good time for beachgoers who don’t mind the heat, particularly in places like Koh Phi Phi and Koh Lipe. Inland cities like Bangkok and Ayutthaya can feel sweltering in the afternoons, so plan sightseeing for early mornings. The north becomes drier and dustier, especially with the onset of the agricultural burning season.
April
April is the hottest month in Thailand, but it’s also one of the most fun thanks to Songkran, the Thai New Year. Celebrated with country-wide water fights, it's a joyful (and cooling) experience. While temperatures can reach well into the 30s°C, beach destinations on either coast offer some respite. Make sure to stay hydrated and take things slow, especially in cities.
May
May marks the beginning of the rainy season in most regions, although downpours tend to be short and sharp rather than constant. The humidity ramps up, particularly in central and northern Thailand. It’s a quieter time to travel, with fewer crowds and lush, green landscapes emerging. The Gulf islands—like Koh Samui, Koh Tao, and Koh Phangan—tend to see better weather than the Andaman coast.
June
June sees more regular rainfall, but it rarely disrupts travel plans too much. The countryside is vibrant, and waterfalls are at their best. While western beaches like Phuket may see more rain, the Gulf coast remains relatively dry, making it a great time for snorkelling and diving around Koh Tao. Expect lower prices and a more relaxed vibe almost everywhere.
July
July brings heavier rains to the north and Andaman coast, but travel is still very possible with a bit of flexibility. Rice paddies turn brilliant green, and misty mountains in the north offer atmospheric views. On the Gulf coast, beach days are still common. Cultural travellers may enjoy this quieter period for exploring temples, museums, and food tours.
August
August is in the heart of the monsoon season, but showers are usually short-lived and followed by sunshine. It’s a great time for nature lovers, as the landscape is lush and full of life. Inland travel can be trickier with occasional flooding, so coastal stays in Koh Samui or Koh Phangan are often the better bet. Festivals and markets continue to run, albeit with fewer tourists around.
September
September is typically the wettest month of the year, particularly in the north and on the Andaman coast. While it’s not the best time for sunbathing, it’s a brilliant opportunity to enjoy Thailand’s cultural side at a slower pace. Think cooking classes, spa days, and temple tours. Prices are at their lowest, and you'll often have attractions almost to yourself.
October
October marks the transition from rainy season to dry season, particularly towards the end of the month. While early October can still be wet, especially in the north, the skies begin to clear by mid-month. It’s a great time to visit Bangkok and central Thailand before the high season crowds arrive. Northern provinces like Chiang Mai begin their cooler season, making trekking and outdoor adventures more comfortable.
November
November is when Thailand really shines. The weather turns reliably dry and sunny across most of the country, especially the Andaman coast. Popular islands like Phuket, Krabi, and Koh Lanta come back to life. In the north, the cooler temperatures are ideal for hiking and exploring rural landscapes. Festivals like Loy Krathong add a magical touch with lantern-lit celebrations in Chiang Mai and Sukhothai.
December
December is peak travel season, thanks to the beautiful weather, festive atmosphere, and Christmas holidays. Beach resorts on both coasts are bustling, so early booking is essential. It’s also a great time to explore Bangkok’s markets and rooftop bars, or take to the hills of northern Thailand for trekking and nature. With low humidity and bright skies, it’s one of the best times to experience the country in full swing.
