Traveller notes on Kep in April
Notes from nearby Phu Quoc (48 km away)
Kep doesn't have its own notes for April yet — these are about Phu Quoc, close enough to share the season.
Phu Quoc-forum threads on April weather describe it as sitting right at the edge of the low-rain season, still officially inside it but with humidity climbing and the occasional scattered storm creeping in as the wet season approaches. Posters are consistent that any given shower runs brief rather than disruptive, and the month keeps its reputation as pleasant for beach time - warm, sunny, with gentler crowds and prices than true peak season. The record actually runs wetter than most forum threads suggest for a nominally low-rain month, a reminder the wetter transition can arrive earlier in a given year than the calendar label implies. The record: 33C days feeling like a punishing 39C, 25.2C nights, a notably high 107mm across 18.4 days, 77 percent humidity, a 31.2C sea and 11.1 hours of sun.
Other months in Kep
Cambodia forum threads are consistent that January sits squarely in the dry season here - lower temperatures, much lower humidity than the wetter months, and genuinely pleasant conditions extending from the November/December stretch through January. One visitor specifically mentioned swimming at Angkoul Beach in January with fine water quality despite the beach itself not being pristine. Kep's famous crab market was the other recurring highlight, with regulars recommending buying fresh crab straight from vendors who'll cook it to order with Kampot pepper. One seasonal note worth knowing: the region's solar salt fields, a nearby attraction, only work and look their best in dry season - during the wet months they're just flooded fields.
Forum posters describe February as a good time to visit Cambodia generally - somewhat cooler than the peak heat ahead but already warming up, and noticeably drier, with leaves dropping from trees and rice fields mostly harvested and dry. Posters do flag genuine dust as a byproduct of this dry stretch. Even within the broader November-February dry season, posters describe a common daily pattern of a sunny, pleasant morning giving way to more cloud by late afternoon, with a real chance of a passing shower or brief thunderstorm by evening - Cambodia's tropical climate means even the dry season isn't fully rain-free. Posters generally pair a Kep visit with nearby Kampot, treating the two coastal towns as a natural combination.
