Aoshima Harbour (Miyazaki)

Aoshima Harbour is a harbour-jetty aided beach/jetty surfing break at the southern end of Aoshima Beach. The jetty helps organize swell so the water can stay rideable when the main Aoshima beach is too big or messy and starts closing out. Waves are described as both right- and left-breaking, with a peeling feel near the jetty. Wind is generally favorable when it comes from the west (and especially west-southwest), where it is described as offshore and helps groom wave faces. Summer afternoons often bring sea breezes, and overall wind conditions are reported as moderate. For the wider Aoshima coast, thermal effects are typically strongest from late morning into the afternoon during the spring-to-early-summer months. Conditions tend to peak in the typhoon-season window, with multiple sources highlighting July through October as the best period for surf energy. Spot-level wind guidance highlights July through September, while surf-forecast style summaries identify July as a top month. Suggested swell direction is south to southeast, and working swell size is reported roughly from about 0.5 m up to around 2.0 m. Safety considerations are important at this location: submerged rocks and above-water harbour hazards (jetty/harbour walls and tetrapods) are specifically noted, along with fisherman lines and boat traffic near the harbour entrance. The harbour also has rules around access—avoid the boat channel, do not surf inside the harbour basin, and respect local fishermen. Lifeguards are not reported at the harbour specifically; sea rescue is managed by Japan Coast Guard and regional lifeguards may be stationed at designated beach areas during peak summer.
