Let weather choose the route shape
The day works better when hot humid days, rainy-season bursts, and evenings that are easier by the river are planned into it early.
- Anchor the day around Royal Palace or Silver Pagoda.
- Keep Wat Phnom for the right weather and timing.
Weather in Phnom Penh is not just a packing note. It decides whether Royal Palace belongs early, whether Wat Phnom still feels sensible, and where you should keep a cafe, mall, museum, or short walk as a fallback.
The practical rule is simple: Royal Palace and riverside first, Central Market nearby, Tuol Sleng as a separate respectful block. That keeps the day grounded instead of making it feel like a loose checklist.
