Key Finding

Destinations like Goa, Mumbai, and Yangon experience dramatic seasonality with 70%+ rain probability during monsoon months dropping to under 10% in dry season. Timing your visit correctly can mean the difference between a dream trip and a washout.

Understanding Monsoon Seasonality

Our "seasonality score" measures the difference between the wettest and driest months. A high score indicates dramatic wet/dry seasons. This is perfect for travelers who can time their visits correctly, but risky for those who book without checking the calendar.

We analyzed 30 years of daily rainfall data to identify not just monsoon timing, but also the best dry season months for each destination. This includes secondary rainy seasons that catch many travelers by surprise.

Year-Round Dry Destinations

Some destinations enjoy consistently low rainfall throughout the year. These "always dry" cities are perfect for travelers who want flexibility without worrying about weather windows.

Monsoon Travel Pro Tips

✅ Shoulder Season Sweet Spot

The first and last weeks of dry season often combine good weather with lower crowds and prices. October in Thailand is a prime example.

⚠️ Don't Trust Averages

A "50% rain probability" sounds mild, but in monsoon regions this often means daily afternoon deluges, not light drizzle.

🏝️ Islands Have Microclimates

Thailand's islands vary dramatically. Koh Samui's east coast is wettest Nov-Jan, while the west coast Phuket peaks May-Oct.

💰 Monsoon = Budget Travel

If you can handle some rain, monsoon season offers 50%+ discounts on hotels and uncrowded attractions in places like Bali and Goa.
