We look forward to seeing you in Siem Reap. The overall vibe of the Event is relaxed and casual, and we want you to feel comfortable and confident throughout. For special occasions, we have put together a few helpful clothing tips based on the planned activities and the expected weather.
The Weather
The Event will take place in June, which marks the beginning of Cambodia’s green (rainy) season. Participants can expect warm tropical weather with occasional short rains and refreshing breezes.
• Average daytime temperature: 30°C – 34°C (86°F – 93°F)
• Average nighttime temperature: 25°C (77°F)
Mosquitoes are present year-round, so insect repellent and light protective clothing (especially at dawn and dusk) are recommended.
Light, breathable clothing, a sun hat, a fan, and a small umbrella or raincoat are recommended for comfort when moving between venues or sightseeing. Please also wear comfortable shoes. There are no restrictions on colours. Some events will be photographed, so consider being a bit camera-ready.
