Trujillo weather in May

Peru's coast forum treats Trujillo and nearby Huanchaco as reliably good through April, the tail end of the region's better weather stretch for surfing, comparable to the pleasant conditions posters described for Lima on the same coast. This stretch of desert coastline is normally quite dry, but forum threads about El Niño years are a reminder that Trujillo can see genuinely unusual, heavier rain when that pattern is active - 2017's flooding came up specifically. In a typical April, though, expect scattered light showers rather than a washout, with warm, humid days good for the beach.

Forum posters describe October as Peru's spring, generally warm and bright without tipping into properly hot - typically 16-23C - with genuinely good sunshine odds along the coast (averaging around 10 hours a day). Posters call October a shoulder-season month with better conditions typically found earlier in the month than toward its end. Trujillo specifically is described by posters as a mild, comfortable coastal city known for its colonial architecture, nearby Chan Chan and Huaca del Sol/Huaca de la Luna archaeological sites, and Huanchaco's famous surf breaks just up the coast - a worthwhile stop for travelers passing through northern Peru rather than only a Lima-Cusco itinerary.
