Understanding Thailand’s Seasons
Thailand’s climate is divided into three seasons, each affecting national park visits differently:
- Dry Season (November-February): Cool (20-30°C), dry, and sunny, ideal for hiking and wildlife spotting. Parks are crowded, and accommodation prices rise.
- Hot Season (March-May): Very hot (30-40°C) with minimal rain, good for coastal parks but challenging for inland trekking. Fewer crowds and lower costs.
- Rainy Season (June-October): Warm (25-35°C), humid, and rainy, with lush greenery and full waterfalls. Trails can be slippery, and some parks partially close, but it’s budget-friendly.
Each season has unique advantages, depending on the park and activities you prefer.
