How this works

This chart shows you 7-days worth of swell/weather/wind information all in place. You have “incoming swell” (in feet) charted by the blue line on the gray graph. You have the weather icons for each day below the graph and you have the wind, speed and direction represented by the directional arrows topped by a blue “wind strength” indicator.

These nearshore wave height forecasts are custom built for each surf region using an average/above-average indicator break as a focal point. These forecasts aren’t just some knock-off of a generic Wavewatch III spectral point being regurgitated, these are true nearshore forecasts that use proprietary algorithms factoring in things like swell windows, island shadowing, bathymetry data, swell-period travel time, and other critical forecast components that tune the nearshore forecast specifically for your region, giving you a good solid overview of incoming swell, weather and wind, so that you can go out and find the best spot to score.

Massachusetts Offshore Swell Forecast

How this works

The Offshore Swell Forecast shows you the 7-day forecast starting at the current time and going out from the latest forecast run. Mousing over any part of the graph (any line including the solid shaded area in the background) will pop up a new box near your pointer that shows the DATE/TIME/COMBINED BUOY HEIGHT in the top of the box, and then the specifics of the line you are hovering over like SWELL HEIGHT, SWELL PERIOD, SWELL DIRECTION (both in Simple Compass direction, like Northwest, and specific degrees 308). If you follow the contour of the line you can see hour by hour how that swell behaves over the course of the forecast period.

*Note: clicking on an individual swell in the legend of the chart you can “hide” that data stream making the chart easier to navigate
