2018/08/23 Swimming Prohibited in Shirahama Leave a reply It is 9:00 PM now. There is a little wind but no rain. I can’t believe this weather condition, the typhoon is landing on Shioku area tonight though. This morning we had heavy rain for a short time and the blue sky appeared after that. But it was prohibited to swim here in Shirahama due to the high waves by typhoon all day long.
