The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right off the bat, we’ve got a bit of a slow start. The surf is there, but it’s pretty ordinary and mixed up with some less-than-ideal conditions for the first few days. The real standout window is looking like the end of the first week and into the second, so don’t be in a rush.
We’re looking at Estaleiro Reef here, a reef setup that’s best with an ESE swell direction. It’s an inconsistent break, so when it’s on, you want to make the most of it. The water temp is about average for the time of year, nothing to write home about.
Starting off Sunday the 16th, it’s a bit of a mess. We’ve got a 6.2 ft swell from the ENE with a short 8-second period, but the wind is a cross-shore from the NNE at 9 mph, stirring up a slight chop. The combined energy is moderate at 731, but it’s a marginal call. The afternoon drops off quickly. Monday the 17th morning cleans up a bit with some light cross-offshore wind, but the swell drops to 4.6 ft. It’s clean, but nothing special. This pattern of small, clean but weak surf continues through Tuesday the 18th and Wednesday the 19th morning, with the swell dropping to 3.3 ft and lighter winds.
Wednesday afternoon the 19th gets ugly with a strong SE cross-onshore wind at 12 mph, so skip that. Thursday the 20th morning is a highlight – we get glassy conditions with a light NW wind, but the swell is only 2.6 ft and the combined energy is weak at 86. It’s a nice morning for a longboard if you’re desperate. Friday the 21st morning has a light offshore wind from the W at 9 mph, with a 3.0 ft swell, making for clean, small waves. The afternoon improves slightly with a 3.3 ft swell and light offshore wind.
Saturday the 22nd looks like a glassy day, particularly the afternoon with zero wind, but the swell is tiny at 2.3 ft and energy is very weak. Things go downhill from Sunday the 23rd through Monday the 24th – a strong SSE wind brings in a messy 4.6 ft cross-onshore chop. Not worth getting wet.
Now, here’s where it gets interesting. The real standout is shaping up for Wednesday the 26th afternoon. The wind swings offshore from the NW at 6 mph, and we get a clean 3.9 ft swell from the E with a 7-second period. The combined energy is moderate at 230. It’s an afternoon session that’s looking clean and fun. But the best of the best is Thursday the 27th morning. We’ve got a light offshore wind from the WNW at 3 mph, a 4.3 ft swell from the E with an 8-second period, and strong combined energy at 370. That’s clean, punchy, and the best on offer for the whole forecast. The reef will be working nicely.
After that, Friday the 28th is a bit mixed with some cross-onshore wind, but the swell holds. The real gem for the second week is Saturday the 29th morning. We’re looking at glassy conditions, zero wind, a 3.9 ft swell from the ESE with a 9-second period, and combined energy of 371. That is a beautiful, clean morning with long-period lines. It’s a bit of a wait, but that Saturday morning is a cracker. The rest of the 29th and into the 30th holds clean but smaller surf, wrapping up with a 3.0 ft swell on Monday the 31st.

Information about the Estaleiro Reef Surf forecast
The above surf forecast table for Estaleiro Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Estaleiro Reef can be found by selecting the local surf guide option on the grey menu. Our Estaleiro Reef 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 (Estaleiro Reef) 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 Estaleiro Reef 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.
