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, I gotta be straight with you – the start of the period is a bit flat and ordinary. There’s a bit of swell around, but the conditions are just not playing ball. We’ve got a run of poor surf quality and messy winds through the first few days, so don’t expect much.

Friday the 4th starts with a small 3 ft SSE swell (period of 11 seconds) and a light cross-off breeze, but the energy is weak at 266. It’s surfable but nothing to write home about. The afternoon turns onshore and it goes to mush. Saturday the 5th drops off to tiny 2 ft SSE swell, and the combined swell energy is a paltry 74. It gets glassy in the morning, so you *might* get a couple of clean knee-high runners, but don’t get your hopes up.

We see a pulse of southerly swell moving in Sunday the 6th, hitting 4 ft in the morning (energy up to 369), but the wind is cross and then onshore, so it’s a mess. Monday the 7th has some better potential: the swell holds around 6 ft to 6 ft from the south, and Monday afternoon turns glassy. That’s a real moment of clarity – combined swell energy at 605 and clean conditions from a dead calm. That’s the best window in the first week for anyone who can handle a solid head-high south swell.

Then we drift into a long stretch of average conditions. Tuesday through to the end of the second week, the swell drops and picks up but never really fires. The energy stays in the low-to-moderate range for days. There’s a small window on Thursday the 10th afternoon with a 4 ft east swell and offshore winds giving clean waves – combined energy at 382 – but it’s a short-period affair at 7 seconds. Not memorable.

By the time we get to Wednesday the 16th morning, we’ve got glassy conditions and a 2 ft S swell (energy 172). But the standout for the whole run is Wednesday afternoon the 16th. It’s a 3 ft swell from the south with a *very long* 14-second period, and the combined energy is 493. The wind is light and cross-off, keeping it clean. That’s real groundswell – proper energy, long lines, and easy paddling between sets. Early morning on the 17th has a bit more size at 4 ft and 12-second period (energy 609), but it’s cross-on so you lose some of that shine.

For the end of the outlook, Thursday the 17th afternoon and Friday the 18th keep that long-period south swell around, but the winds get onshore or on it, making things messy. By Saturday the 19th, it’s dropping and pretty grim.

If you’re looking for the pick of the bunch: Monday the 7th afternoon’s glassy 6 ft south swell is a solid call for a clean, head-high session. And that Wednesday the 16th afternoon – with the 3 ft, 14-second groundswell and clean glass – is a proper long-period treat for the point break. It’s not huge, but it’ll have shape and push.

Stay tuned, forecasts can always shift.

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.
