The Lowdown

Alright folks, Rusty here. Let’s take a look at what the ocean’s got cookin’ for us over at Arpoador.

Right off the bat, don’t get too excited. The first few days are pretty flat and messy. We’ve got a bit of a slow start with no real juice to get the heart pumping. The real action is parked way out in the second week, so we’ve got a bit of a wait.

Looking at Wednesday the 5th, it’s a bit of a tease. The swell is tiny at 3ft from the south with an 11-second period, and that cross-shore wind isn’t doing us any favours. It’s a marginal call, and I’d say save your energy.

Thursday the 6th morning is where we see a glimmer. A clean 2ft south swell with a nice north offshore wind. It’s small, but it’ll be glassy and rideable for the absolute beginner. The water is sitting at 73°F, which is a touch warmer than normal for this time of year, so you won’t need a thick suit.

The first real standout, and I mean the only one worth circling on the calendar, hits on Monday the 17th of August in the morning. This is for the crew who know what they’re doing. We’re looking at a solid 8ft swell from the east-southeast, but here’s the kicker: it’s backed by a light, clean north-northeast offshore wind. The combined energy is massive at 1708, so you’re getting proper power. The period is only 9 seconds though, so it’s a bit windswell-y and not the super clean groundswell we’d dream of for a point break, but at Arpoador, with that offshore wind, it’s gonna be firing. This is strictly for experienced surfers – 8ft is too much for the beginners. The crowd factor is likely high, as it usually is here, but on a day like that, you’ll be sharing the peak with a few hungry locals. It’s the best on offer, no question.

Before that, we’ve got a couple of other days worth mentioning. Saturday the 16th shows some promise, with 7ft and 7ft from the south-southeast, also with a clean cross-off wind. The combined energy is huge (1736 and 2098), but the guidance flags it as marginal. It might be worth a look, but the Monday swell is the one I’d gamble on.

After that big Monday, the swell drops fast. Tuesday the 18th and Wednesday the 19th see it fade back to knee-to-waist high slop, with some glassy moments on the 19th morning but nothing to write home about. Thursday the 20th morning has another clean 4ft south swell, but the wind picks up later and chops it out.

So, to sum it up: wait for Monday the 17th. That’s your day. The rest is a waiting game.

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.
