The Lowdown
Alright folks, Rusty here with the long-range outlook for Praia da Boraceia. The water's sitting at a touch warmer than normal for this time of year, coming in at 72°F.
The next week and a half has a bit of a slow start, but there's some decent energy building towards the end of the first week and into the weekend. We’ll see some small, clean conditions to get the week started, but the real standouts are the sessions on Sunday the 20th. That’s where the juice is.
We kick off Monday the 14th with a small 3ft SE swell rolling in. The wind is glassy and the waves are clean. The combined swell energy is moderate at 200, and with the period around 8 seconds, it’s a short-period swell, so the shape won't be world-class, but for a beginner-friendly spot, it’s a fine way to start the day. The afternoon stays glassy, with the swell dropping to 2ft but the period bumping up to 9 seconds.
Tuesday the 15th is a bit of a mixed bag. The morning has a 3ft S swell, but the wind is cross-on, creating some ripples. The afternoon cleans right back up with glassy conditions and a 3ft S swell.
Wednesday the 16th brings a glassy morning but with only 2ft of swell, though the period is a long 13 seconds, meaning you’ll be waiting for those sets. The afternoon gets messy with an onshore wind.
Thursday the 17th sees the swell size bump up to 4ft from the S, but the cross-on ESE wind keeps things from being perfect. The combined energy is strong, hitting 640 in the morning and 492 in the afternoon. This is not a standout session.
Friday the 18th is a good morning call. Clean glassy conditions with a 4ft S swell and a solid 12-second period. The energy is moderate to strong at 485. The afternoon turns onshore and the period drops off, so make the most of the morning.
Now, Saturday the 19th morning brings a clean 5ft ESE swell with glassy winds. This is getting into the intermediate zone, but the conditions are clean. The afternoon sees a cross-on wind.
The best on offer is Sunday the 20th. The morning brings a clean 6ft ESE swell with a light cross-off breeze, and the combined energy is strong at 795. The afternoon is even better: a 6ft E swell with a light offshore wind, and the energy jumps to a very strong 835. The period is a bit short at 8-9 seconds, so it won’t be the most powerful walled-up wave, but for clean, punchy beach break waves, this is the pick of the fortnight. It’s a bit much for the beginners, but the rest of you will have a blast. This spot is fairly consistent, and crowds are possible.
After that, Monday the 21st and Tuesday the 22nd drop back down into the small, ordinary range. The energy drops right off, with values in the 80s and 170s.
There’s a real dry spell from Wednesday the 23rd through to the 27th, where the swell drops below 2ft and the energy is weak, below 50. Not worth paddling out for.
There's a potential little pulse on Thursday the 24th with a 5ft S swell and glassy morning conditions, and a clean 4ft S swell on Friday the 25th. The period on the 25th hits 11 seconds, and the energy is moderate. That could be a nice glassy session, but it’s not a standout compared to the Sunday the 20th.
The final days of the month, the 28th and 29th, show a bit more energy returning, but with onshore and cross-on winds, it’s marginal.
So, for my money, get out there early Friday the 18th or, if you can wait, make the trip for Sunday the 20th. That’s the one.
Rusty.

Information about the Praia da Boraceia Surf forecast

A general guide to surfing at Praia da Boraceia can be found by selecting the local surf guide option on the grey menu.

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 Praia da Boraceia 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.
