Since rain is rare, you won’t need waterproof gear, but a compact umbrella can be useful for the occasional shower in February or March. If you plan to swim, the ocean is warmest from January to April, but even in cooler months, the water stays swimmable. A small backpack for day trips and a reusable water bottle will help you stay comfortable in Трухильо’s dry air.
