Frequently asked questions

Does the rainy season really ruin a trip?

Usually not entirely — rain typically falls as heavy but short afternoon downpours rather than all-day drizzle, and mornings often stay clear. December-February is still visited, with lower prices and fewer tourists as a trade-off, but flooding is possible in some regions during the wettest weeks.

Is July-August worth the crowds?

Weather-wise, yes — it's the most reliably dry and sunny stretch. But it coincides with European summer holidays, so popular spots like Bali get crowded and prices rise. Book well ahead, or shift to June or September for similar weather with fewer people.

Best month for a first trip balancing crowds, weather and price?

June or September: reliably dry season weather without the peak-season crowds and prices of July-August.
