A Month in Phnom Penh in the Rains on $1,233 Each

Phnom Penh rain does not arrive as weather. It arrives as a decision you have already lost. At about half past three the light goes the colour of old brass, the motorbikes thin out, and then the sky opens all at once and the street outside our building turns into a shallow brown river that runs past the doorway with somebody's flip-flop in it. It lasts an hour, sometimes two. Then it stops, the drains swallow the water, the food carts come back out, and the evening is the cleanest, coolest part of the day. By the end of the first week we had stopped checking the forecast and started treating four o'clock as a fixed appointment.

We came for a month in the wet season on purpose, which is not the month anybody sells. October is the tail of the southwest monsoon, when the city is at its greenest, its air is at its cleanest and its rent is at its softest, and it costs you roughly an hour a day of standing indoors. This is what that month actually came to, and what it gave back.

The season sets the schedule

The dry season runs December to April, when overnight temperatures can drop to about 22C; the monsoon runs May to November with 84 per cent humidity behind it. The Deutscher Wetterdienst normals for the city make the shape plain: rainfall climbs from 34.8 mm in March to 270.9 mm in September, which is 21.5 days out of 30 with rain, and October is barely behind at 248.1 mm over 19.3 days. Days are hot all year, with mean maxima of 31.6 to 35.3C, so the wet season changes the timing rather than the temperature. It is also when the air is worth breathing: the city's annual average is 66 US AQI, rated Good, and the bad readings come in the dry months.

The practical version: work in the morning, write off the afternoon outdoors, and do anything you actually want to do after six. It turned out to be a better working rhythm than the one we brought.

What the flat cost, and the thing nobody lists

Numbeo's September 2026 page puts a one-bedroom in the centre at $646.36 a month and the same flat outside the centre at $370.33; nomads.com quotes a one-bedroom studio in the centre at $643. A median hotel room is $13 a night, about $267 a month, and the Airbnb median is $59 a night. We took the centre, in BKK1, split two ways, so our rent was $323. Utilities for an 85 square metre flat run $106.17 by Numbeo's basket, and our half was $53 with the aircon at night.

The thing nobody lists is water pressure. Half the older buildings here fill a rooftop tank and hope. A nomads.com member writes flatly that Airbnb listings around $20 to $25 a night came with slow wifi, no hot water, or no water at all, and that raising the nightly budget fixed it. It is the most useful advice we took into the month, and the reason we paid above the floor: our building had a pump, a genuinely hot shower and a landlord who answered messages. Ask about the stairs too, because a ground-floor room on a street that floods is not the room in the photos.

Seventeen megabits, and the fifty-four the network actually delivers

Phnom Penh carries the region's worst wifi reputation and, as usual, it is measuring somebody's router rather than the country. nomads.com's community average reads 17 Mbps and is rated Slow, which is honest about a $22-a-night guesthouse room. Measured, the city is elsewhere: Speedtest's August 2026 city row puts Phnom Penh's fixed network at 54.19 Mbps down and 54.37 up with 5 ms latency, ranked 140th, and mobile at 182.20 Mbps, ranked 50th. The mobile number is the one that matters: it is faster than most hotel wifi on earth and costs almost nothing.

Numbeo prices the 60 Mbps-plus home plan at $24.89 and a 10GB-plus SIM at $7.42; a member renews a SMART SIM with 44GB for about $5. Our fibre was the cheapest useful line in the ledger and never blinked, storms included. The $100 coworking desk is the line I would cut: members name Workspace1 at the Factory and Suzy Anti-cafe, which are good, but I used the desk eight times in thirty days. The Phnom Penh living page carries the current rates and the honest caveat, which is the same everywhere: test the apartment's connection on your own laptop before you sign a month.

Cash, and the city that closes at nine

Cambodia runs on cash and Phnom Penh runs on it harder than anywhere else in the region. nomads.com's line for the city is blunt: cash only, especially for foreigners. Dollars and riel circulate side by side and riel comes back as change for dollars, which is how you end up with a wallet full of notes and no idea what any of it is worth. The prices never stung: a dinner is $4, a cafe coffee $3, a draft beer $1, a taxi across town about $3.

The stranger adjustment is bedtime. The city shuts down around nine, and it is a feature once you have spent a month in a capital that does not. Before nine there is the night market on Sisowath Quay, five kilometres of riverside with food stalls and kids on scooters; inland there is the Art Deco dome of the Central Market, the best building in the city, and the Russian Market with its factory seconds. After nine it is quiet enough to hear the rain on the awning two rooms away.

The two days that are not a holiday

You cannot live a month here and skip the other history. Tuol Sleng, the former high school the Khmer Rouge ran as the S-21 prison, and Choeung Ek, the killing fields a short ride out of town, are the two sites everyone means when they say they went to Phnom Penh; in July 2025 they were inscribed on the UNESCO World Heritage List together with the M-13 prison west of the city. Our city guide covers what to expect; what it does not convey is how quiet a museum full of visitors can be. We went on a dry morning, which is the only scheduling advice I would give, and did nothing useful for the rest of that day.

The ledger

This is the honest accounting, with the source for each line, because a budget without a basis is just a story. Figures are per person for two of us sharing a central one-bedroom for thirty days, converted at 4,062.60 riel to the dollar (open exchange rates, 15 October 2026), and they exclude flights.

The month came to roughly $1,233 each, with one caveat. nomads.com, checked live today, puts the nomad tier for this city at $1,526, the expat tier at $1,300 and the local tier at $838, and our own living page from ten days ago still read $1,514, so the index moved $12 in ten days. Both numbers are true: the tiers assume a flat to yourself, taxis instead of motos and a full coworking membership, while our total assumes half a rent, market food and a desk I mostly wasted.

Where the city pushed back

Traffic is the real hazard, and the ratings say so: nomads.com grades traffic safety Bad and walkability only Okay. Nobody walks slowly here and nobody stops for you; what eventually worked was moving at a constant pace and letting the motorbikes plan around me, the opposite of every instinct I have. Hospitals are the second hard line: the city scores one out of five on nomads.com's top-hospital index, which means private clinics for everyday problems and Bangkok for anything serious, and travel insurance with evacuation in the budget rather than a drawer.

The one-month extension on the Ordinary visa, about $45 to $55 through an agent, is on our Cambodia visa hub, along with the registration trap that gets more extensions rejected than any paperwork: your landlord has to enter you into the FPCS system, and immigration checks it digitally. Ours did it the same week we arrived, and I would ask before signing rather than after.

The smaller costs were structural rather than financial. English is graded Bad outside hospitality and coworking, so a translation app earns its keep. There are no nomads here in the Canggu sense at all: nomads.com records 0 per cent of its members based in the city against 537 reviews from people passing through, so you will not be adopted by a scene. What you get instead is a city actually lived in by Cambodians, which was the point of coming this far.

Would we come back in the rains

Yes, and October specifically. The month cost what a mid-tier European city charges for a single room, and it bought a one-bedroom in the centre, 54 Mbps fibre for the price of two coffees, clean air at the dirtiest time of year everywhere else in the region, and an hour of enforced stillness every afternoon that I ended up protecting. The practical side is on the Phnom Penh living page, the sightseeing on the city guide, and if you are weighing the region, the month we spent in Saigon is the same exercise at a bigger scale and a higher rent. Phnom Penh does not sell itself the way its neighbours do. It quietly costs less, rains harder and shuts earlier, and after a month that felt like the first honest pace we had kept in a year.
