The Lowdown

Alright, let’s talk about Arpoador. The next couple of weeks are a proper mixed bag. We’ve got a slow start with some small, ordinary waves, but there are a few windows where it’s gonna light up. The water’s running a touch warmer than usual for this time of year, so that’s a little bonus.

The first few days, Thursday the 6th through Saturday the 8th, are pretty lackluster. We’re looking at ankle to waist-high dribble, mostly in the 2ft to 4ft range. The swell energy is weak, and even when it bumps up on Saturday afternoon, the period is a short, crumbly 8 seconds. It’s surfable, but you’ll be fighting for scraps. Not worth getting worked up about.

Sunday the 9th is where things start to get interesting. The morning brings a cleaner 5ft of south swell with a better 14-second period. The energy is solid, and with a light offshore wind, it’s gonna be glassy and lined up. This is the first real standout. Get out there early because the afternoon turns into a cross-on mess.

Monday the 10th and Tuesday the 11th are a write-off. The swell holds around 5ft to 6ft, but the wind is onshore and the conditions are choppy. It’s a battle, not a surf. The energy is there, but the quality is junk.

Wednesday the 12th cleans up a bit with a cross-off breeze and 5ft of south swell. It’s not perfect, but it’s rideable. The real magic happens on Thursday the 13th. The morning is looking prime: 5ft of south swell, a solid 13-second period, and a clean offshore wind. Energy is pumping. This is the one to circle on the calendar. It’s got the size, the power, and the clean conditions.

Friday the 14th starts with some clean 4ft waves, but the afternoon gets blown out with a strong onshore. Saturday the 15th and Sunday the 16th are messy. The swell is up around 6ft to 6ft, but the wind is all over the place. Sunday morning has some clean 6ft waves but with a short 8-second period, so it’ll be a bit soft and crumbly.

Monday the 17th is another standout. The swell pushes up to 7ft to 7ft with a clean, cross-off wind all day. The energy is strong. This is solid, powerful surf. It’s a bit bigger, so it’s not for the beginners, but for the crew who know what they’re doing, it’s gonna be firing.

After that, the energy drops off quickly. Tuesday the 18th through Friday the 21st sees the swell fade back down to the 2ft to 3ft range. The ocean’s gonna go quiet again. The period drops, the energy is weak, and we’re back to small, ordinary conditions. It looks like a few days of flatness after that initial burst of size.

So, to sum it up: your best bets are the mornings of Sunday the 9th and Thursday the 13th, with Monday the 17th being the big, powerful one. Get on it when it’s good, because the lulls are long.

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.
