During the wet season, waterproof shoes and a compact umbrella are essential. Opt for quick-drying fabrics and layers, as mornings can be sunny before the afternoon rain arrives. Mosquito protection is wise in any season, but especially when standing water is more common. A small backpack will help keep your belongings dry during sudden showers.
