Planning tips for Chennai
- Compare the weather and fare columns above together — the cheapest month isn't always the best-weather month.
- Shoulder-season travel (just before or after the busiest months) often balances good weather against lower prices.
- Book 4-8 weeks ahead where possible — a general pattern, not a guarantee for this specific destination.
- Check nearby airports above if Chennai has real alternatives — a short extra journey can mean a much lower fare.
- Factor in local public holidays and school terms at your destination, not just at home — prices and crowds follow both.
- Re-check rainfall, not just temperature — a warm month can still be a very wet one.
