The Lowdown

Alright, let’s get into it. This is Rusty, and I’m looking at the forecast for Castelejo, a beach and reef setup that’s exposed to the NW swell. Honestly, it’s a rough start with no real surf to get excited about for the first ten days. The wind is a constant problem, blowing from the NNW at 15 to 25 mph, cross-on or onshore, making a mess of things. The swell is small, mostly under 3 ft, weak period of 5 seconds, and the combined energy is weak, in the 50s and 60s. It’s all poor surf conditions, chop and lump. Not worth paddling out.

The first real flicker of hope comes on Wednesday, July 30th. The morning will still be tricky with a strong offshore from the ESE at 25 mph, which cleans things up but makes it hard to paddle into the 3 ft NW swell. The afternoon is where it’s at – a moderate offshore breeze from the SE at 15 mph, clean conditions, and the swell is 3 ft from the NNW with a 10-second period. The combined energy is moderate (260). This is a window for a few clean lines, but the size is small.

Then Friday, August 1st looks like the standout. The morning is glassy – literally a slight air from the ENE at 3 mph. The water temp is about 69°F, which is normal for the time of year. The swell is 2 ft from the NW, period of 10 seconds, and the energy is moderate (108). The wind will be offshore and glassy, meaning the waves will be clean and peeling. The break is very consistent, so you won’t be waiting forever. The swell direction (NW) matches the optimum (NW) perfectly. Crowds are possible here, so don’t expect it to be empty. This is your best bet for a decent session.

After that, it drops off again. The weekend brings tiny 1.0 ft to 2 ft swells with periods between 8 and 12 seconds, but the wind turns onshore or cross-on, so it’s back to poor conditions. The long period groundswell (12 seconds) on August 2nd is interesting, but it’s only 1.0 ft, so it’s really a non-event for a beach and reef setup. The energy is weak (82-100). The whole second week is a write-off.

So, to sum it up: the first ten days are a washout. Your best shot is the afternoon of July 30th for a clean, small wave, but the real winner is the morning of August 1st with that glassy offshore wind and a clean little groundswell. Get out there if you can, but don’t expect much else.

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.
