Experimental Surf Forecast Matrix

* EXPERIMENTAL - NOT FOR OPERATIONAL USE *

Experimental Surf Forecast Matrix

In the tabs below you can view Surf Forecast Matrices for various beaches over the Boston/Norton, MA forecast area. This product is experimental and not intended to be substituted for the official Surf Zone Forecast, which can be viewed HERE. Additional information on this project and variable definitions can be found HERE. We are seeking feedback on this over the next several months, so please send us your input via an online survey.

The Rip Probabilities included in the matrices below are from a rip current forecast model tied to NOAA's Nearshore Wave Prediction System. This model predicts the probabilities of hazardous rip currents occurring using output from the nearshore wave model and predicted tide levels. Values are calculated from 0-100%, hourly through 144 hours.
