The Lowdown
Alright, grab a coffee, I’m Rusty. Let’s get into it.
For the next 16 days, Arpoador is looking at a bit of a slow start, but there’s a couple of proper windows where it’ll really turn on. The first week is mostly small and clean but unremarkable, then you’ll see a big spike of energy around the second week that’s worth circling on the calendar.
The first proper surfable windows kick off from Saturday, 1 August. The morning is clean with a light NNE offshore breeze, but the swell is tiny at 2 feet from the south. The energy is weak (152), and the water is warm at 73°, about 2° warmer than average for this time of year. It’s a beginner-friendly wave, but it’s nothing to get excited about. The afternoon gets spoiled by a cross-shore wind, so that’s a write-off.
Sunday, 2 August, the morning flips to a northerly offshore, but the swell drops to 2 feet from the ESE and the period is a short 6 seconds. Combined energy (74) is weak. It’s surfable, just ordinary. The afternoon gets messy again.
Monday, 3 August, is a standout morning for the early bird. Glassy conditions, WSW wind at 0 mph, and clean 2 feet ESE swell. Energy is low (56), but that glassy surface will make it feel better than it is. If you’re a beginner, that’s your best bet for the first week. The afternoon turns cross-onshore and choppy.
The rest of the first week (Tuesday through Friday) continues the pattern: small, clean mornings with offshore or light cross-off winds, but the swell rarely tops 2 feet. The energy stays weak (54–191). The only real change is Wednesday, 5 August, when the morning adds a little push from the south with 2 feet, 12-second period, and combined energy (191) edging into moderate. Still, it’s just ordinary.
Then, from Saturday, 8 August, things start to lift. The morning has 3 feet from the south, 9-second period, and a clean offshore flow from the north. Energy (167) is moderate. The afternoon is even better—still 3 feet, but the wind goes light offshore, keeping it clean. That’s a solid, fun session for all levels.
The real standout is Tuesday, 11 August. The morning shows 8 feet south swell with a long 14-second period, and the combined energy is a massive 2469. That’s strong, powerful surf. However, it’s cross-onshore with a light breeze, so the surface will have a bit of texture. At 8 feet, this is only for experienced surfers. The afternoon gets even bigger—10 feet at 17 seconds, but the wind is onshore and strong (16 mph), making it poor. This is a day for the experts only, and only if you’re very picky with the tide.
Wednesday, 12 August, is the absolute peak of the forecast. The morning is glassy, with a NE wind at 0 mph, and a solid 6 feet S swell at 14 seconds. Combined energy (1321) is strong. That’s as good as it gets—clean, powerful, long-period groundswell. At 6 feet, it’s still manageable for strong intermediates, but the long period (over 11 seconds) means it’ll be a bit more challenging at the beach break. The afternoon turns onshore, so hit it early.
The following days (Thursday 13 to Sunday 16) taper off but remain promising. Thursday and Friday (13th and 14th) bring 4 feet to 5 feet south swell with moderate energy (483–919) and cleaner cross-off winds, especially Friday afternoon. By Saturday, 15 August, the morning is back to 4 feet from the south, 12-second period, with a light offshore NNE breeze at 6 mph. Energy (407) is moderate, and conditions are clean—another good session. Sunday, 16 August, repeats that formula, with a morning offshore flow and 4 feet south swell, then the afternoon gets ruined by a strong onshore wind.
Arpoador is a consistent, fairly exposed beach break, and it’s best for beginners to intermediates on the smaller days. The crowds are likely to be present, especially on the cleaner days, given the rating. The standout windows are definitely Monday, 3 August for the glassy morning, and Wednesday, 12 August morning for the powerful, clean groundswell. The long period (14 seconds) will make the waves more shaped and powerful, but it’s a beach break, so expect some closeouts on the bigger sets. The 11 August is for experts only.

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.
