Month-by-Month Breakdown

HIGH SEASON (Nov–Feb) ⭐⭐⭐⭐⭐

• Weather: Perfect (25-30°C, low humidity)
• Crowds: High
• Prices: High (book 2-3 months ahead)
• Tim's Take: "Worth it. This is when I go."

HOT SEASON (Mar–May) ⭐⭐

• Weather: VERY hot (35-40°C)
• Crowds: Medium
• Prices: Medium
• Tim's Take: "Only if you love heat or are on a tight budget. Songkran (mid-April) is cool, though."

RAINY SEASON (Jun–Oct) ⭐⭐⭐

• Weather: Rain 1-2hrs/day, humid
• Crowds: Low
• Prices: Low (deals everywhere)
• Tim's Take: "My secret weapon. Still 80% sunny, way cheaper, fewer tourists."
