A general guide to surfing at Teniente (Lieutenant) can be found by selecting the local surf guide option on the grey menu.

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 Teniente (Lieutenant) 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.
