Surface data from Open-Meteo, visibility from Copernicus Marine / NOAA CoastWatch.
How the score works
Every spot gets a composite score out of 100. Satellite Secchi depth is the dominant factor (0-100 base), multiplied by surface condition penalties, then safety-capped.
Underwater visibility0-100
Secchi depth from Copernicus Marine satellite data (NOAA VIIRS fallback). 20m+ is gin clear. Below 3m you can barely see. This is the dominant factor in the score.
Wave heightMultiplier
Flat water is ideal for entry and exit. Above 1.2m waves create surge underwater and dangerous shore conditions. Above 2m the cap kicks in.
Wind speedMultiplier
Calm conditions mean better surface visibility and safer boat diving. Above 25 km/h most dive operations cancel.
Water temperatureContext only
Shown for exposure protection, thermocline and safety planning only. It does not affect the diving score.
Frequently asked questions
How often is this updated?
Surface conditions update every 3 hours from Open-Meteo, including water temperature for exposure planning. Underwater visibility data updates daily from Copernicus Marine (primary, 1 to 2 day lag) and NOAA VIIRS (fallback, weekly composites).
How is the diving score calculated?
A multiplicative penalty chain: Secchi depth base (0-100) multiplied by wave height, wind, current, rain, atmospheric visibility and water quality factors. Water temperature is displayed separately for comfort, safety and kit context, and does not affect the score.
What does 'visibility data unavailable' mean?
Satellite ocean colour data can have gaps near coastlines because of land masking and cloud cover. PeakWave does not publish a diving score when neither measured nor inferred underwater clarity is available. Surface conditions and safety flags can still be shown separately.
What types of diving does this cover?
Freediving, spearfishing, and recreational scuba. The scoring optimises for conditions that suit all disciplines: clear water, calm surface and manageable current. Water temperature is shown separately for exposure protection planning.
Where does the visibility data come from?
Copernicus Marine Service (primary) blends multiple satellites into a gap-free daily product with direct Secchi depth measurement. NOAA CoastWatch VIIRS (fallback) derives Secchi from Kd490. Both at approximately 4km resolution, so conditions can vary at the waterline.
Are these the same spots as the surf leaderboard?
They use the same coastal catalogue. Great surf days and great diving days are often opposites: divers want flat, calm, clear water while surfers want swell and energy.
