How to use this buoy or model
Naha 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
Naha 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.
Frequently asked questions about this station
What is Naha?
Naha is a physical or reference marine station for Japan, identified as JP-NOWPHAS-702 and published in SwellOracle with source attribution.
Where does the data for Naha come from?
The source shown for this page is NOWPHAS / MLIT Japan. SwellOracle preserves the station identifier and distinguishes measured observations from model estimates.
Does Naha have a current reading?
A source observation is available and its timestamp is displayed on this page. Always check that time before using the values because marine feeds update on different schedules.
Why does Naha have or not have a history chart?
This station is not yet in the history capture set. SwellOracle does not create a chart until a reusable, correctly identified series exists.
