Do more with Buoycast Pro

AI condition summaries read the latest observations and the forecast, then write a plain-language briefing of what to expect on the water. On iPhone 15 Pro and newer the language model runs entirely on your device, so nothing leaves your phone, and every summary links back to its sources. Older devices fall back to a rule-based summary.

Custom threshold notifications push you the moment wind, waves, gusts, temperature, or pressure at any buoy cross the limits you set, with AND/OR logic for combined conditions.

NOAA watches, warnings, and advisories arrive as push notifications the moment they are issued.

Interactive weather maps with animated radar, wind, and pressure, plus forecast-vs-observation charts on every data type with 12-hour history.

Apple Watch complications, Home and Lock Screen widgets, custom section order, and iCloud sync across your devices, with no ads. Start Your Free Week.

Built around one question: should I go out today?

AI condition summaries, in plain language

Buoycast reads the latest observations and forecast and tells you what they mean right now, in a sentence or two. On iPhone 15 Pro and newer the summary is generated on your device by an on-device language model, with no server round trip. Tap for sources any time you want the raw data behind it.

See how the forecast held up

Buoycast overlays the NOAA and WeatherKit forecast against the observations recorded at the buoy, on every data type, with 12-hour history. See how the last forecast held up before you lean on the next one.

I don’t have to go topside and turn on weather channel or fire up PC or TV… I just open this app and my nearshore weather and forecast is there and in a very pleasing format. I love it!

This is the best marine weather app out there as far as I’m concerned. It’s clear, simple and gives all the pertinent information that you need to get out on the water!

Able to find all my local and regional marine forecasts. Also great for planning longer voyages to waters outside my local area.
