The Lowdown
G’day, Rusty here. I gotta be straight with you – the next week or so at Arpoador is pretty flat and nothing special. We’ve got a long stretch of small, weak waves with only a little pulse here and there. The water’s sitting at 71°, which is about average for this time of year, so no surprises there.
The first real standout doesn’t show up until Friday, July 31st. That’s when a solid 6ft swell from the S starts rolling in with a very long 12-second period, packing serious energy (1265). The morning is the pick – glassy, offshore NNE wind, clean as a whistle. The water will be clean, the waves will have some punch. This is a proper groundswell, so it’s better suited to the point and reef setups, but for the experienced surfer, this is the best on offer over the whole 16-day window. The combined energy is strong (1265), and with that period, you’ll get long waits between sets, but the paddle out will be easier. Keep in mind, this is a week away, so it’s promising but not locked in.
Saturday, August 1st morning is also worth a look – 5ft swell from the SSE, 12-second period, and clean offshore NE wind. The energy is moderate (616), and it’s a good option for the morning, but the afternoon turns ugly with strong cross-onshore wind.
After that, Sunday the 2nd and Monday the 3rd drop off again – smaller 4ft to 5ft swell, light onshore wind, and ordinary conditions. The Monday morning is glassy but the waves are only 4ft with a short period, so it’s not going to get the heart racing.
Overall, the standout is that Friday the 31st morning. Get on it if you can. The rest of the time, it’s a waiting game. Arpoador is a fairly exposed spot, so when the swell and wind line up, it can fire. But for now, it’s mostly a flat spell.
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.
