The Lowdown
G’day, Rusty here. Look, I’m not gonna sugarcoat it – the next week and a half is a write-off for serious surfing at Castelejo. This exposed beach and reef setup is copping a beating from the wind for days on end, and the swell is messy. We’ve got a long stretch of poor conditions from July 25th all the way through to August 4th, with only a couple of tiny windows that might be worth a paddle if you’re desperate.
The first real glimmer of hope comes on Thursday the 30th of July. It’s not a standout, but it’s the first time the wind plays nice. The water temperature is about average for this time of year. Thursday morning sees a tiny 1ft swell from the WNW with a period of 10 seconds, and a rare cross-offshore breeze from the SSE. The combined energy is weak (74), so you’re looking at small, clean little waves. The real magic is Thursday afternoon – glassy conditions with an ENE breeze at 3 mph, and that same small 1ft WNW swell. It’s not going to blow your mind, but it’ll be clean and surfable, with the combined energy dropping to 69. This is the best of a bad bunch for the first week.
Friday the 31st of July holds a little more promise. Friday morning brings some clouds, a tiny 3ft WNW swell with a period of 11 seconds, and glassy conditions with a NE breeze at 3 mph. The combined energy is moderate (158), and the glassy wind will make it clean. The longer period (11 seconds) means a bit more shape and energy, and the light air will make paddling out easier. Friday afternoon is less appealing with onshore wind.
After that, it’s back to the choppy, onshore mess from August 1st through to the 4th, with lumpy, cross-onshore winds and poor surf conditions. The swell gets a bit bigger, but it’s all wind-affected and ugly.
The best chance of the whole outlook arrives on Thursday the 6th of August. Thursday morning sees a 6ft swell from the NW with a period of 7 seconds, and a gentle cross-onshore wind from the NNW. The combined energy is moderate (290), but that short period means the waves will be a bit fat and crumbly. Thursday afternoon bumps up to 6ft from the NW, still with a short 7-second period, and a moderate onshore breeze. The combined energy hits 317. This is the biggest swell, but it’s blown out by the onshore wind, so it’s not a clean session. It’s borderline for experts at this size, but the wind is a problem.
Honestly, the standout moment is the glassy, clean conditions on Thursday the 30th of July afternoon and Friday the 31st of July morning. The swell is tiny, but the lack of wind makes it the only surfable, clean option. For the rest of the period, the wind is a killer. If you’re a kitesurfer, this exposed beach setup with consistent cross-onshore wind and moderate swell might be more interesting than it is for a paddle surfer.
Rusty.

Information about the Castelejo Surf forecast
The above surf forecast table for Castelejo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Castelejo can be found by selecting the local surf guide option on the grey menu. Our Castelejo 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 (Castelejo) 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 Castelejo 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.
Castelejo is 25 km (16 miles) from Lagos. If you plan a holiday in The Algarve, look for hotels and other accommodation in Lagos. Lagos has rooms for a wide range of budgets as well as car hire and transport links.
