5 climate regions, 3 seasons: This guide helps you find the perfect timing.

### **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."

### **Regional Breakdown**

- **Bangkok**: Year-round, avoid April heat
- **Chiang Mai**: Best Nov-Feb, smoky Feb-Apr
- **Phuket/Andaman**: Nov-Apr (west coast)
- **Koh Samui/Gulf**: Feb-Sep (east coast)
- **Pattaya**: Year-round (microclimates)
