Local climate notes
Siem Reap is roughly 15% drier than Phnom Penh over the year but has a wider day-night temperature range because it sits further from the sea. For Angkor visitors, November to February is the window: dawn can drop to 18–20°C, cool enough to walk the temple complex for hours. In April the sandstone surface temperature can exceed 45°C at midday, which is why most itineraries split into an early-morning and a late-afternoon session.
