Will my clothes dry if I wash them in a sink?

In high humidity, it can take up to 48 hours for cotton to dry. Stick to synthetic-blend or linen items, which can dry in 12-18 hours even in damp air.

Should I bring a rain jacket?

Only if it is 'breathable' or a lightweight windbreaker. Standard rubberized raincoats will make you sweat so much you'll end up just as wet on the inside.

Packing for Hot and Humid Climates

Prioritize loose-fitting, breathable natural fabrics like linen or merino wool and pack at least two sets of lightweight clothes per day to account for sweat. Use dry bags for electronics and keep your carry-on strictly to items that handle moisture well to avoid mold and mildew.

Choose your fabrics carefully. Avoid 100% polyester, which traps heat. Go for linen, hemp, or lightweight merino wool. These materials allow airflow and dry quickly if they get damp from rain or humidity.
Use packing cubes for airflow. Do not overstuff your suitcase. If your clothes are packed tightly, they will smell musty within 24 hours. Use mesh packing cubes to allow air to circulate around your clothes inside the bag.
Protect your electronics. Humidity kills gadgets. Place your camera, phone, and power banks inside a sealed dry bag or a large Ziploc bag with a few silica gel packets to absorb excess moisture.
Plan for multiple outfits. In high humidity, clothes don't dry overnight. Bring 30% more underwear and socks than you think you need, and ensure every shirt you bring is light enough to be rinsed in a sink and hung to dry.
