Conditions at Ibaraki in October
October: Autumn Swell Builds
October is when Ibaraki starts to roar back into full surf season. Average swell height climbs to 1.7m (5.6ft), period sits at 9.5s, and the swell rose shows a powerful easterly push: E (25.2%), ENE (23.7%), NE (12.7%) and ESE (13.3%). These are often well-organized swells from typhoon remnants and strengthening North Pacific lows. The problem is wind: ideal offshore conditions drop to 17%, with NE (22.5%) and NNE (17.0%) winds blowing hard on many days. This means the window for truly clean surf is narrow, but when a low pressure system moves through and winds clock west or northwest, the beach can be firing with hollow, lined-up surf. Water temp is still very manageable at 20.7°C, air 18.6°C, and precipitation is high at 6.58 mm/day. Keep the schedule flexible.
