How to use this buoy or model
Hosojima is part of SwellOracle's Japan surf and swell coverage. This page preserves the source identity and timestamp so you can judge whether the reading is useful for your coastline. Because this is an observation or reference station, gaps and delays can occur when the upstream feed is unavailable.
- Start with the observation time; stale data should not be treated as current surf.
- Read height together with period and direction; one number alone does not describe wave quality.
- Compare this page with nearby locations only when their source and update time are clear. Source: NOWPHAS / MLIT Japan.
How to use this reading
Hosojima helps confirm whether swell energy is reaching the Japan area. Higher height with a longer period usually means more organized energy, while direction determines which coastlines receive that swell best.
For surf decisions, compare height, period and direction with your beach's local exposure. If the station does not report a variable, use the app to compare it with nearby model points.
Observation history not available yet
This station is listed as a physical reference, but it is not part of the current history capture set. SwellOracle only shows charts after enough reusable observations have been stored.
