New! Interactive 3D maps for over 10,000 dive sites, including 2,400 in high definition. Plus visibility alerts when the water near you is forecast to be unusually clear.
Know what you'll see before you dive — the first app to forecast both marine life abundance and underwater visibility, at dive sites worldwide.
Updated daily. Pick the right site, the right day, and the right season before you ever get wet.
WHY DIVESIGHT
Weather apps help tell you if you can dive. DiveSight also tells you how good it's likely to be — how much marine life you're likely to encounter and how far
you'll see, days in advance, anywhere in the world. It's the difference between hoping and making decisions based on the best ocean intelligence available.
THE FORECASTS
- Marine Life Index (0–100) of abundance for every site, updated daily — see which days will be better than usual, up to a week ahead.
- Underwater visibility — including the tens of thousands of sites no crowdsourced app has reports for. DiveSight predicts visibility worldwide from
satellite data and fisheries oceanography. Plan your dive with confidence.
– 10 years of monthly climatology per site: water temperature, visibility, currents, weather, wind, and more — so you can pick the actual best month to go, year over year.
– Depth-resolved conditions: temperatures at the surface, 10m/30ft, and 30m/90ft, plus currents, waves, tides, sun, and moon. Everything you want to know about conditions.
FIND YOUR NEXT DIVE
– By destination — browse a heat map of 28,000+ dive sites across 1,400+ regions. Zoom into Raja Ampat, Cozumel, the Red Sea, Komodo, the
Maldives, the Galápagos, or the hidden sites between them.
– By creature — search 6,000+ marine species and see exactly where and when you can dive with them:
hammerheads, mantas, mola mola, whale sharks, mandarinfish, thresher sharks, nudibranchs, and thousands more. Every species linked to the sites, seasons, and
regions where it appears.
– Around you — tap once to see every dive site within range, sorted by today's conditions, marine life, or distance. Perfect for
layovers, road trips, and your local shore dive.
– By season — a calendar of bucket-list events with predicted timing windows: the sardine run, manta cleaning stations, hammerhead schools, whale shark aggregations, mobula ray gatherings, and spawning events. Find what's peaking right now — and where to go for it.
WHO IT'S FOR
Scuba divers planning a liveaboard, a weekend boat, or a shore dive. Snorkelers and freedivers chasing clear water and big animals. Vacation

I’ve been waiting for an app like this since I started diving…in particular the weather forecasting and the marine wildlife finder! Accurate weather predictions are really the backbone of a successful dive trip and DiveSight does it better than other apps I’ve used. Finally having the ability to build a list of all the sea critters I’ve encountered is a game changer for me. What a comprehensive and vital source of ecological data I now have at my disposal.
Well designed and easy to navigate
Jack jack1234567890
I appreciate the thoughtfulness put into the design of this app, SO much useful information easily accessible. It’s been great to learn about all the dive sites near me and all the wildlife I might see. Super helpful tool!
Useful forecasts
psychonautica
Lots of features and cool data aggregated into forecasts. The forecasts seem accurate so far for my local sites and looking forward to testing them abroad on an upcoming trip. Could be a game changer for dive planning and logging.
Developer Response
Thank you, this means a lot. The forecasts are the hardest part of DiveSight and where most of the work goes: billions of satellite and ocean-model data points, run through models wevalidate against actual conditions. It's still a forecast, so it won't always be perfect, but hearing it held up at sites you know is exactly what we worked so hard for... and how we keepmaking it better.
Great exploration tool

Really impressive detail from the pins in the explorer tool. Really excited to plan some dives at spots in Lake Huron that I learned about from like 30 seconds navigating in the map feature.
Developer Response
