The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Arpoador over the next couple of weeks.
Right off the bat, we’ve got a bit of a slow start, but don’t tune out just yet. The first few days are pretty ordinary with small, weak waves and light winds, but there’s a real standout building in the middle of the period that’s got my attention. The water temperature is sitting about average for this time of year, so no need to dig out the thick suit just yet.
Saturday 29 August and Sunday 30 August are pretty tame. Saturday morning has some small 2ft swell from the S with a bit of period (11 seconds) but combined energy is weak (114). The offshore NNE wind keeps it clean, but it’s barely a ripple. By Sunday, the wind shifts onshore and the swell drops further – not worth paddling out for.
Monday 31 August sees a light NE offshore in the morning on a 2ft ESE swell. Clean, but tiny. The energy is still low (70). Afternoon stays clean with a cross-off breeze, but the size is still just 2ft. Fun for a longboard if you’re desperate, but not much else.
Tuesday 1 September is a write-off – onshore wind and weak swell. Wednesday 2 September brings a big spike in swell – 8ft in the morning and 13ft in the afternoon from the S and SSW, with periods around 13-14 seconds. The energy is huge (3964 and 8714), but the wind is onshore and choppy. This is a big, raw, messy ocean – better suited to experienced surfers or maybe even kite gear, not a clean paddle session.
Thursday 3 September is the real standout. Morning session with a clean 6ft S swell (10 seconds) and light NNE offshore winds. The energy is moderate (683) but the conditions are superb – clean, offshore, and decent size. This is the best wave of the whole forecast by a long shot. Afternoon gets a bit cross-shore and messy, but the morning is gold.
Friday 4 September is back to small and clean, but nothing special. From Saturday 5 September through Monday 7 September, the swell is tiny and the wind is mostly onshore or cross-off, with energy well under 200. Not much to write home about.
Tuesday 8 September morning brings another solid pulse: 7ft S swell with a 13-second period, light offshore N wind, and clean conditions. The energy is strong (1315). This is a proper groundswell, and Arpoador’s fairly exposed setup should handle it well. Just watch out – the afternoon turns onshore and choppy, so get it early.
From Wednesday 9 September through Friday 11 September, the swell hangs around 4ft to 6ft from the S and SSE, with decent periods (12-14 seconds). The mornings are often clean with light offshore or cross-off winds. Friday morning in particular looks good with a 4ft SSE swell, 14-second period, and a light NE offshore – clean and lined up.
Saturday 12 September and Sunday 13 September fade out quickly. Saturday morning is clean but small (3ft), and Sunday morning is glassy but tiny (2ft). The swell is just about done.
So, the true standout is Thursday 3 September morning – 6ft S swell, offshore NNE wind, clean, and fun. The second best is Tuesday 8 September morning – 7ft S swell, again offshore, but a bit bigger and more powerful. Both are worth setting the alarm for.
Rusty.

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.
