Koh Samui's tropical climate means it's generally hot and humid all year round, but if you want to enjoy Hin Ta and Hin Yai, also known as Grandfather and Grandmother Rocks, in optimal conditions, the best time to visit is between December and February. During these months, the weather is at its most pleasant with minimal rainfall, lower humidity, and temperatures ranging from a comfortable 25°C (77°F) to 29°C (84°F). This period, also known as the 'cool season', is ideal for exploring the natural sights, lounging on the beaches, and of course, experiencing the famous rock formations without the discomfort of heavy rains or extreme heat.
However, if you're looking for a mix of good weather and fewer crowds, consider planning your visit in either the late end of February or early March. This is when the peak tourist season starts winding down, and you can enjoy Hin Ta and Hin Yai with a bit more tranquility. Keep in mind that the weather pattern can be unpredictable, and sporadic showers can occur, but they usually pass quickly. On the flip side, if you’re on a tighter budget, the months between April and June and then again in October and November may present better deals for accommodation, although you'll need to be prepared for hotter temperatures and the start of the rainy season, respectively.
