The Lowdown
Alright, Rusty here again, but in feet and miles this time. Let’s break down Ponta Do Rapa.
This reef doesn’t break all that often, so when it does, it’s worth paying attention. Water temp is a normal 67° for this time of year.
The next few days are lackluster. Tuesday afternoon has a 5-foot S swell, but the wind is cross-on, so it’s choppy and messy. That sets the tone. Wednesday and Thursday see waves from 4ft to 7ft, but the wind stays dirty – cross or cross-on – and the notes say it’s marginal at best.
Friday the 28th gets rough with a short 8-second ENE swell and moderate energy, but the wind ruins it. Cleaner on Saturday morning and afternoon, but the swell is only 5ft from the ENE and energy is weak, so it’s just ordinary. Sunday morning is a washout.
Then a bright spot. Monday the 31st goes dead calm in the morning – glassy – with a 4ft ENE swell. That’s rare here. Clean, small waves. Tuesday the 1st of September is also glassy to start with a 4ft ENE swell, but a 35 km/h wind wrecks the afternoon.
The big standout is Wednesday the 2nd of September. A solid 10ft south swell arrives with a 10-second period, and the combined energy hits 2438 in the morning. That’s heavy, expert-only territory – way over 8ft. The wind turns cross-off in the afternoon, cleaning it up. That’s the session to aim for.
The rest is smaller. Thursday and Friday fade, but the 4th of September has a clean offshore wind and 4ft SE swell. On the 7th of September, there’s a clean 5ft SSE groundswell with a long 13-second period and energy at 699, but that’s a week and a half out, so keep an eye on it.
The call: Wednesday the 2nd of September is the big one – massive swell, clean afternoon wind, expert only. Monday the 31st morning is your small, glassy backup.
Rusty.

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 Ponta Do Rapa 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.
