Bluewater Forecast
Marine Weather.
Free · Designed for iPad. Not verified for macOS.
New in 1.3: Inshore Topo — creek and pass bottom structure from NOAA lidar and sonar, 1 ft contours, 2D and 3D. Plus waves, wind, tides, buoys and radar for US coasts.
Bluewater Forecast is a map-first marine weather app for inshore and offshore anglers, surfers, sailors, divers and boaters.
It puts the forecast on a chart and covers the next five days for 45 locations on the US Atlantic, Gulf, Pacific and Hawaii coasts. Turn on the layers you need and they render over your coastline.
WHAT YOU GET (FREE)
• Buoys — NOAA NDBC stations nationwide: wave height, period, wind, water and air temperature, pressure, updated every 10 minutes
• Waves — height, period and direction from GFS-Wave, hour by hour to five days, with the swell trains split out
• Wind & gusts — NOAA HRRR 3 km for the first two days, the NWS National Blend to day five, drawn as streamlines
• Tides, water levels and currents — NOAA CO-OPS predictions, observed water level against the tide (surge shows as the gap), and tidal current stations
• Radar and clouds — NOAA MRMS quality-controlled radar (non-precipitation echoes removed) and GOES-East imagery, plus forecast cloud and precipitation fields when the clock is moved forward
• Sea surface temperature (NASA MUR), NWS marine alerts, NOAA artificial reefs, the NOAA nautical chart
• A one-screen dashboard for your spot: conditions, tide, sun and moon, a five-day meteogram, the nearest buoys
• Saved spots, and push alerts when a spot's wind, swell and tide line up
BLUEWATER PRO
• Inshore Topo — bottom structure for creeks, passes and flats from NOAA topobathy lidar and sonar surveys, rendered at about 3 m: 1 ft contours in the shallows, relief shading for holes and ledges, intertidal flats marked, and a 3D mode that tilts the chart over the surveyed bottom. Covers the 45 dashboard locations.
• Temperature breaks — labelled isotherms from NASA MUR sea surface temperature, in °F
• Fishing hotspots — a composite that scores where temperature breaks, colour changes, current edges, eddy edges and bathymetric slope coincide
• Ocean currents and eddies — Copernicus Marine forecast currents as flowing particles, with sea-height rings that trace the eddy edges
• Chlorophyll — NASA PACE ocean colour, the boundary between blue and green water
DESIGNED FOR THE WATER
A dark, high-contrast chart built to be read in sunlight. Forecast fields are prepared on our servers ahead of time, so most views load in about a second, and the last forecast for a saved spot stays on screen while a weak connection catches up.
ONE CLOCK
Move the time from now to five days out and every forecast layer follows — wind, waves, clouds, currents, tides. Observation layers fade when the clock leaves the present rather than presenting old data as a forecast.
FREE TO USE
The forecast, buoys, radar, charts and map are free. Bluewater Pro is an optional subscription managed on our website; sign in with a Pro account here and its layers unlock.
Bluewater Forecast is an independent app, not affiliated with NOAA, NASA or Copernicus. It is a planning tool — never for navigation or safety-of-life decisions. Inshore Topo depths are relative to NAVD88 (about mid tide), survey dates vary by area, and conditions at sea change faster than any forecast.
Ratings & Reviews
• Inshore Topo (Pro): creek and pass bottom structure from NOAA lidar and sonar surveys, 1 ft contours, 2D and 3D, at all 45 dashboard locations
• Radar now uses NOAA MRMS quality-controlled reflectivity, which removes non-precipitation echoes
• Currents and the offshore Pro layers are prepared per coast in advance, so most views load in about a second
• Phone fixes: easier dashboard pull-up, tidier legends, 2D/3D switch on the full chart, faster start
