Weather uncertainties 2025 to go to Sihanoukville ?
When traveling in the tropics as a seaside, rain is not welcome. If you see this indicator, with possible storms, that does not mean that it will rain all day long. When we observe the local rainfall, it is either really zero or very weak. Meteorologists prefer to be pessimistic. So observe below, the skies photographed during a week announced stormy in Asia. It did not rain once. I invite you to integrate this parameter before going to Sihanoukville for a good trip to the sun!
