Thailand in January: Weather, Beaches and More!

January is perhaps one of the best times of year to visit Thailand. Temperatures during this month range from the lows of around 15°C in the north around Chiang Mai to the highs of 29°C. But the weather is even more tempting in Bangkok, with the lows of 21°C. The highs in the city settle at around 32°C. This means that those trekking in the tribal villages of the north will not struggle with the heat and it is still cool enough to explore the capital’s highlights before setting sail through warm tropical waters to some of the most enchanting islands on the planet for a getaway like no other.

If beaches are calling your name, the Andaman Sea’s islands, like Phuket and Koh Phi Phi, are at their best in January. Snorkel or dive in the crystal-clear waters, relax on white sandy beaches, or take a speedboat tour to the iconic Maya Bay.

Koh Samui and the nearby Ang Thong National Marine Park are ideal for a tropical retreat. Kayak through limestone cliffs, hike to hidden lagoons, or simply unwind on the palm-fringed beaches. January’s calm seas make it the best time for island-hopping adventures in the Gulf of Thailand.

Outdoor enthusiasts should head to Khao Sok National Park, home to ancient rainforests, dramatic limestone cliffs, and the stunning Cheow Lan Lake. Here, you can hike, kayak, or stay in floating bungalows for a unique experience.
