A general guide to surfing at Rio Grande Jetties can be found by selecting the local surf guide option on the grey menu. Our Rio Grande Jetties 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. If you surf the same spot (Rio Grande Jetties) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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 Rio Grande Jetties 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.
