The Lowdown
Alright, listen up. The next couple of weeks are looking pretty small and quiet at Arpoador. We've got a few windows of clean, surfable waves, but nothing that's gonna blow you away. The first real chance to get wet comes on Sunday, the 26th of July. The morning is the pick of the whole outlook, honestly. We’re looking at a clean 2ft south swell with a solid 14-second period—that's nice, groundswell energy that will wrap in well. Winds are glassy, dead calm from the WNW. The water temp is sitting about average for this time of year, so you'll be comfortable. The combined energy is moderate at 377, so there's enough there to push you around. It’s a beginner-friendly break and the waves will be clean and fun for a longboard or a mini-mal. But heads up, crowds are likely, that spot gets busy.
After that Sunday morning, it drops off. Sunday afternoon the wind swings onshore and turns it to chop. The rest of the 26th is a write-off after lunch.
Monday the 27th morning and Tuesday the 28th morning stay small, with a 2ft to 2ft south swell, but they’ll be clean with offshore winds, so if you’re desperate for a paddle, it’s an option, just very ordinary. The combined energy drops to 205 and then 113, so it’s weak.
We then hit a flat spell. From Wednesday the 29th all the way through to Saturday the 1st of August, the mornings offer glassy or offshore conditions, but with tiny 2ft to 2ft swell and combined energy sometimes below 100. It’s barely breaking, to be honest. A long, slow period. Not worth running for.
Sunday the 2nd of August morning is glassy again, but with a weak 2ft, 10-second south swell. Energy is 120. Still just small, clean, and ordinary.
Now, a notable shift shows up around Wednesday the 5th of August. The afternoon gets interesting—a 4ft east swell, short period at 8 seconds, so it'll be a bit lumpy and crumbly on the banks, but the wind is clean offshore from the ENE. Combined energy jumps to 315. That could be fun on a fish or a groveler.
The real standout? That’s Thursday the 6th of August afternoon. We’ve got a 5ft east-southeast swell, still short period at 8 seconds, but here’s the key: offshore wind from the NE at 6 mph and clean conditions. That’s 5ft of shore-break style energy, combined energy of 426. It’ll be chunky and fun for a shortboard, but at that size, it’s pushing past beginner territory. For a more experienced surfer, that's the session to target.
Then the outlook is a bit spread out. Sunday the 9th of August morning has a 4ft south swell with offshore wind—that’s clean, moderate energy of 381, worth a look. But by the afternoon, a strong 19 mph cross-onshore wind kills it. Kite surfers might be interested there, but for paddle surfing, that afternoon is a mess.
Monday the 10th of August starts with onshore wind and rain, so any remaining swell is blown out.
So, bottom line: grab Sunday the 26th of July morning if you want the cleanest, most user-friendly waves. For a bit more power and punch, circle Thursday the 6th of August afternoon—that’s the best bigger swell in clean, offshore wind. The rest is small and average at best.

Information about the Arpoador Surf forecast
The above surf forecast table for Arpoador provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Arpoador can be found by selecting the local surf guide option on the grey menu. Our Arpoador 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 (Arpoador) 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 Arpoador 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Arpoador is 14 km (9 miles) from the very large city of Niteroi. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Niteroi. Niteroi has rooms for a wide range of budgets as well as cheap car hire and transport links.
