Seasonal Weather in Phnom Penh: What to Expect Throughout the Year (and How to Survive It)

okay, so phnom penh. where do i even start? it’s… a lot. like, a lot a lot. i've been bouncing around here for a good six months now, and honestly, the weather is the first thing you gotta wrap your head around. it's not just 'hot.' it's a whole vibe.


basically, it's a rollercoaster. here’s the lowdown, broken down by season, the way your slightly-caffeinated friend would explain it over a cheap Angkor beer.

*Dry Season (November - April): AKA The Golden Period (But Prepare for the Heat)

this is when everyone tells you to come. and yeah, it's pretty awesome. the skies are generally clear - picture that impossibly blue kind of blue you only see in travel brochures. humidity? manageable. not nonexistent, mind you. but it’s way less oppressive than the other times of the year. average temperatures hover around 30-35°C (86-95°F) during the day. evenings are a sweet relief, usually dipping down to the low 20s Celsius.

pro-tip: hydrate like your life depends on it. seriously. and sunscreen. don't be a hero. also, be prepared for some dust. it’s a constant companion, like that one annoying coworker.

drunk advice: don't even think about wearing anything you can’t live without washing. you’re gonna sweat.

Rainy Season (May - October): AKA The Great Water Show (And Mosquito Buffet)

this is where things get… interesting. the rain isn't constant downpours, more like prolonged, sticky drizzle, punctuated by occasional torrential thunderstorms. it’s humid.
very humid. think you like humidity? get ready for a whole new level. pack accordingly. lightweight, breathable clothing is your friend. rubber boots are a lifesaver.

the air hangs heavy, thick with the smell of wet earth and blooming jasmine. the city takes on a softer, almost muted quality. it's not depressing, just… different. you might find yourself getting unexpectedly cozy indoors, reading a book or trying that new cooking class you’ve been eyeing.

overheard gossip: “did you see the flash floods near Tonle Sap? Apparently, it’s been worse than they predicted this year.” you can check local news and updates on Khmer Times

review: a local warned me about the mosquitoes. and honestly? they're relentless. pack DEET. lots of it. or consider mosquito netting. you'll thank me later.

Geographic Context - A Quick Peek Elsewhere*

Just a short flight (or bumpy bus ride, if you’re feeling adventurous) puts you in Thailand, where the monsoon season is already in full swing, or in Malaysia, where the dry season is just beginning. It's a good reminder that Phnom Penh's weather is just one piece of the Southeast Asian puzzle.
