Information about the Mangersta Sands (Lewis) Surf forecast

A general guide to surfing at Mangersta Sands (Lewis) can be found by selecting the local surf guide option on the grey menu. Our Mangersta Sands (Lewis) surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Mangersta Sands (Lewis) may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
