I have booked to go to Sanya next week, and the weather forecast is moderate rain. Will it be affected if I swim? Does the rain usually stop the next day or now?

Moderate rain should not have much impact, because Sanya predicts that moderate rain showers will generally not rain, and it will have little impact on daytime travel at night, that is, even if it rains during the day, it will not last more than half an hour, and it will have little impact on tourism, so you can rest assured to play.
