How to Survive Monsoon Season in Cambodia
Cambodia's monsoon season (June-October) brings daily downpours, flooded streets, and challenging humidity. But with the right preparation, it can actually be enjoyable — fewer tourists, lush scenery, and cooler temperatures.
How do I Survive Monsoon Season in Cambodia?
Expect 1-3 hours of heavy rain daily (usually afternoon). PP streets flood regularly — learn which roads to avoid. Run AC/dehumidifiers to fight mold. Keep rain gear and dry bags in your backpack. Use Grab/PassApp during rain rather than motorbikes. Mosquito prevention is essential.
Prepare your home
Buy dehumidifiers ($30-80 each) for bedrooms and closets. Stock silica gel for electronics. Check windows and doors for leaks. Move valuables to upper shelves if ground-floor apartment. Install drain covers to prevent insects entering during floods.
💡 Run your AC for at least 2 hours daily even when away — the dehumidification prevents mold buildup.
Waterproof your daily carry
Invest in a quality dry bag for your laptop ($15-30). Waterproof phone case ($5-10). Compact rain poncho (better than umbrella on a motorbike). Waterproof sandals for flooded streets. Keep a change of dry clothes at the office if commuting.
💡 A $15 waterproof backpack liner saves you from ruining a $1,000 laptop — worth every cent.
Master monsoon transport
Rain typically hits 2-6 PM. Plan errands for the morning. Use Grab/PassApp cars during downpours (surge pricing applies). If riding a motorbike, pull over during heavy rain — visibility drops to near zero. Learn your area's flood map — some streets become rivers after 30 minutes of rain.
💡 Phnom Penh flood-prone areas: Monivong Bridge approaches, parts of Toul Kork, and low-lying areas near Bassac River.
Manage health risks
Apply mosquito repellent daily (DEET-based). Sleep under a bed net if windows lack screens. Drink only bottled water — flood-contaminated tap water is a risk. Avoid wading through floodwater (leptospirosis risk). Keep anti-fungal cream handy for humidity-related skin issues.
Enjoy the monsoon perks
Angkor Wat without crowds (stunning with monsoon clouds and green moats). Countryside is lush and photogenic. Lower hotel and flight prices. Tonle Sap Lake at its fullest. Spectacular lightning displays. Cooler temperatures (28-33 C vs 38-42 C in hot season).
💡 Some of Cambodia's most beautiful photos are taken during monsoon — the dramatic skies and green landscapes are unmatched.

💡 Tips

- • The first rains of monsoon (late May/early June) are the most dramatic — streets flood worst before drainage clears.
- • Waterproof your important documents (passport, blue card) in a zip-lock bag year-round.
- • Embrace the rain — sitting in a cafe watching a monsoon downpour with a good coffee is one of Cambodia's great pleasures.
