Hotels in South Thailand, Thailand

South Thailand hugs the Andaman Sea and Gulf of Thailand, with a tropical climate that stays hot year-round (80-95°F / 27-35°C). It's famous for its limestone karst islands and world-class diving spots like the Similan Islands. Between November and April, the dry season lets you snorkel in crystal-clear waters near Railay Beach, while May to October brings monsoon rains that keep prices low and crowds thin. The west coast (like Phuket) gets more rain during summer, but the east coast (like Koh Samui) stays drier-so you can pick your adventure based on the season.
