The Lowdown

Right, folks, Rusty here. Let's have a look at what's cookin' at Castelejo over the next couple of weeks.

Honestly, it's a bit of a rough start. The first week or so is looking pretty average, with a fresh onshore wind blowing consistently from the NNW. The swell is tiny, around 1 ft to 5 ft, and the period is short (4 to 7 seconds), so the waves will be pretty weak and messy. The combined swell energy is in the low to moderate range (33 to 156), but with that wind, it's not going to be much fun. We're talking poor surf conditions right through until the 27th of July. Don't bother paddling out for that unless you fancy a fight with the chop.

But then, hold on to your board. The outlook changes completely around the 28th of July. The wind swings around to a light offshore breeze from the ESE, and the swell starts to muscle up. We're looking at a solid groundswell from the NNW, with wave heights around 6 ft to 8 ft, and the period stretching out to a clean 8 to 9 seconds. The combined energy jumps right up – we're talking values in the 500 to 1000 range, which is serious wave energy.

The standout window is the morning of the 29th of July. The swell is a clean 7 ft from the NNW, with a period of 9 seconds and a light offshore breeze from the south. The combined energy is a massive 1021, and the conditions are described as "excellent for experienced surfers." That's a proper session for the crew who know what they're doing. The morning of the 30th of July is also a beauty, with a glassy 7 ft swell from the same direction. That's a top-tier call, but remember, 7 ft is for the experienced riders.

The end of the run into the first of August still has some size, around 6 ft to 8 ft, but the wind is back onshore, making it a bit of a gamble. For the beginner surfers, stay away from the bigger days, especially when it's over 5 ft, and the 8 ft plus days are for experts only.

Keep in mind, Castelejo is a beach and reef setup, and it's very consistent. The crowds can be a thing here sometimes, but with the conditions on offer, it's worth the company.

So, to sum it up: the first week is a write-off. The real action kicks off on the 28th of July, and the 29th and 30th of July are the clear standouts. Get your skis on for those.

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.
