What to pack

For a trip to Wa during the dry season (November to March), pack lightweight, breathable clothing to stay comfortable in the heat. A wide-brimmed hat, sunglasses, and sunscreen are essential for protection against the strong sun. Evenings can be mild, so a light jacket or shawl may come in handy.

If you’re visiting Wa during the rainy season (June to September), waterproof footwear and a compact umbrella or rain jacket will help you stay dry. Quick-drying clothes are a good idea, as humidity levels rise. Don’t forget insect repellent, as mosquitoes can be more active during this time.

For the transitional months like April, May, and October, layering is key. Light, long-sleeved shirts and trousers can protect you from both the sun and occasional rain. A small backpack for day trips will help you carry essentials like water, sunscreen, and a light rain cover.
