Alright folks, Rusty here. Let’s get into it.

Right off the bat, I’m gonna be straight with you – the next week and a half is a write-off for Castelejo. We’ve got a solid 12-day stretch of nothing but onshore slop, messy wind, and tiny or weak swell. It’s a real bummer. The water temperature is sitting at 69°, which is basically average for this time of year, so that’s not the issue – it’s the wind and the lack of clean, organised swell.

The only real glimmer of hope comes much later, right at the tail end of the 16-day window. Keep your eyes on Wednesday the 22nd and Thursday the 23rd of July.

On Wednesday morning, we finally see a shift. The wind swings offshore from the ESE at 6 mph, and the swell is a solid 4 ft from the NNW. That’s a proper groundswell with a 8-second period, enough to get some decent lines at Castelejo. The energy is moderate (274), and the conditions are clean. That afternoon it stays clean with a cross-off wind, same size swell. This is where it gets interesting.

Thursday the 23rd of July is the standout. Morning glass-off conditions with a light ESE wind, and the swell bumps up to 6 ft from the NNW. The energy jumps to 785 – that’s a noticeable bump in power. The wave comment says “very good surf conditions,” and with that offshore wind, it’s going to be clean and punchy. This is your best bet for the whole outlook. The afternoon stays good with a smaller 5 ft and light cross-off breeze.

Friday the 24th morning is also a winner – glassy conditions with a 6 ft NNW swell and 348 energy. But the wind shifts onshore by the afternoon, so get out early.

After that, it’s back to the same old story on Saturday the 25th with onshore winds and messy surf. The long-range swell on the 25th afternoon has a huge energy reading (1007) but it’s paired with a stiff 22 mph onshore wind, so it’s a no-go for surfing – that’s kite territory.

So, to sum it up: you’ve got a long wait, but Wednesday the 22nd through Friday the 24th of July mornings offer some proper, clean waves. The best of the lot is Thursday morning. Don’t sleep on it.

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.
