The Lowdown

Alright, Rusty here. Let’s cut through it. For the next couple weeks it’s mostly a bust. Wind is gonna wreck most of it, and the surf quality just ain’t there. There’s one little window right at the end, but you’ll need to be patient.

Starting Monday the 27th of July, forget it. Clear sky, but the wind is messy. Swell is small, around 3 ft from the NNW, period only 7 seconds, so it's weak. Combined energy is 129. Water temp is 66°, which is 4° colder than normal—so it’s much colder than usual for July, and that’s a big deal. It’ll bite. Morning has a light cross-shore, but it goes onshore in the afternoon. Total junk.

Tuesday the 28th is no better. Swell stays around 3 ft from the NNW, period bumps up to 10 seconds, but the wind is cross-onshore in the morning and onshore in the arvo. Choppy. Wednesday the 29th is more of the same—small, weak, onshore. We're stuck.

Thursday the 30th, swell drops to just 1 ft. Combined energy is 69. Wind is moderate and cross-onshore. Friday the 31st: 3 ft swell but a period of only 5 seconds—pure wind chop. Poor.

Into August, same story. Saturday the 1st, a slight lift to 4 ft from the NNW, but period is still short at 7 seconds, and a fresh breeze from the NNW makes it lumpy on Sunday the 2nd. That holds all the way through to Thursday the 6th of August. Swell stays between 2 ft and 3 ft, period short, wind a solid 22 mph from the NNW. Junk.

Now, things get bigger but not better. From Friday the 7th of August, the swell really builds. By Saturday the 8th, we’re seeing 6 ft to 7 ft from the NW, with combined energy 406-446. But period is only 8 seconds, so it’s a raw, building sea. And the wind is fresh from the NNW at 22 mph, cross-onshore. Lumpy and blown. By Sunday the 9th, it’s up to 8 ft from the NNW, energy hitting 735. That’s strong energy, but it’s messy and onshore. That size is too big for beginners, and with the onshore wind, only experts will want to battle it, but the quality is poor. This continues through Monday the 10th.

The only real standout in the whole run is Tuesday the 11th of August. Finally. The wind goes glassy in the morning from the east at just 3 mph. Swell is still a solid 7 ft from the NNW, period 8 seconds, combined energy 515. That glassy wind will clean it right up, giving the only window of good surf. Castelejo is a beach and reef setup, so that 8-second period is fine for it. The morning is the pick. Crowds are listed as “sometimes,” so it might get a few out for that rare clean session. That 7 ft size is getting into intermediate-to-advanced territory. The afternoon shifts to a light cross-onshore; quality drops.

So overall, it’s a long, frustrating wait. From Monday the 27th right through to Monday the 10th of August—over two full weeks of poor conditions. The only real hope is that one morning on Tuesday the 11th. For a break that’s usually very consistent, this is an unusual blank stretch, but it happens. Forecasts can change, but as it stands, mark that Tuesday morning and hope.

Stay patient.

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.
