Kep in October

November through April offers the best weather – dry, breezy, and temperatures around 28°C. December and January get busy with European visitors escaping winter, so book accommodations early. May through October brings monsoon rains and humidity that makes walking uphill feel like a workout. But room rates drop by half, and you'll have the crab market mostly to yourself. The rain usually comes in afternoon bursts, leaving mornings clear for beach time. Avoid Cambodian holidays like Pchum Ben (September/October) when domestic tourists pack the beaches. Hotel prices triple and restaurants run out of fresh crab by noon.
