Updates in  hr  min  s Forecast update imminent

Alright, I’m callin’ it as I see it, and what I see is a long, tough stretch. The 16-day outlook starts now, and up until Sunday the 12th of July, there’s basically zero worth paddling out for. Small, weak, and all blown out by onshore or cross-onshore winds. From the 6th to the 12th, that’s almost a full week of flat to knee-high junk.

The only thing that even looks like a wave shows up on Sunday the 12th of July morning. That’s at Castelejo (beach and reef). This spot is very consistent and open to NW swell, but it’s a tough spot. We’re looking at a 4-foot NW swell (that’s 1.2m) with a 8-second period. The combined energy is moderate at 234. Winds will be light cross-onshore from the west at about 6 mph (10 km/h), so the surface will be a bit crinkly but not totally blown out. It’s barely enough for a marginal session.

This 4-foot swell is small enough for beginners if the tide cooperates, but the short 8-second period means the waves won’t have any punch, and they’ll just close out. This isn’t a groundswell – it’s windswell. The afternoon of the 12th gets choppy and messy again.

After that, the rest of the forecast is poor. Onshore winds hammer the waves, and the energy drops off a cliff. By Wednesday the 15th of July, the combined energy is only 101 – that’s barely a ripple. There is one slot on the 14th with an 11-second period, but it’s buried under 15 mph onshore winds (25 km/h), making it a total whiteout.

So, here’s the bottom line: Sunday the 12th morning is your only hope. Bring a longboard or a soft-top, find a mushy shoulder, and don’t expect much. For the rest of the run, the wind is too strong and the swell too small. Honestly, this stretch looks better for kite surfing when the wind really gets going.

No standout quality here. A long blank stretch like this is pretty normal for this region when the swell and wind don’t play nice.

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.
