Angkor in the rain
Wet stone, mist and full moats: many photographers prefer the temples like this. Mornings stay workable for the big circuits.

The short answer
What July is really like
July averages around 211 mm in Siem Reap across roughly 25 rainy days, but the operative word is "days with rain", not "days of rain". The standard pattern holds: clear-enough mornings, a violent, dramatic hour in the late afternoon, washed streets by dinner.
With arrivals at their annual floor alongside June, this is the month for travellers who prioritise atmosphere and value over certainty. It is also when European summer holidays begin nudging numbers back up: early July is quieter than late.

Where to go in July
Mondulkiri waterfalls
The falls run at full force: this is what the highlands look like in their element. Trails are muddy; guides are worth it.

River, caves between showers, long café afternoons. Kampot suits the green-season pace better than almost anywhere.

Tips for July
- Build slack into intercity days: rural roads slow down after storms.
- Waterfalls, paddies and river trips are the July highlights: lean into water rather than fighting it.
- Leeches exist on highland trails in the wet, long socks and a check at the end, nothing dramatic.
- Book flexible-rate rooms: green-season discounts are wide and walk-in bargaining works.

Frequently asked questions
Does July rain wreck a Cambodia trip?
It rarely should. Rain concentrates in late-afternoon bursts; mornings are usually usable. Plan outdoor headliners early, keep afternoons flexible, and July gives you the sights nearly to yourself.
Is Angkor quiet in July?
Yes: July ties with June for the fewest international arrivals in the Ministry of Tourism data. Even sunrise feels human-scaled.
Can I go to Koh Rong in July?
It is the island’s wettest stretch (about 465 mm) with rough seas and occasional cancelled boats. Doable and cheap, but only for the flexible.
