The Lowdown

Second text (imperial):

Alright folks, Rusty here. Let’s get into it for Castelejo. We’ve got a bit of a rough start ahead, but there’s a little window of hope later on if you can wait it out.

The next week and a half is pretty grim, to be honest. From now through the 27th of July, it’s a write-off. The wind is mostly cross-on or onshore and fresh, chopping up the small swell. We’re talking waves around 2ft to 4ft, with short periods of 4 to 7 seconds, and the combined energy is weak to moderate – mostly between 47 and 101. It’s just not worth paddling out, the conditions are poor. The water temp is about average for this time of year, so no surprises there.

Then, things start to look up on the 28th of July. Tuesday morning is a bit of a tease with a clean 2ft NW groundswell (period 10 seconds) and light cross-offshore wind from the ESE, but the energy is still moderate at 123. It’s surfable, but ordinary. The real standout is Tuesday afternoon. The wind swings to a light offshore from the SSE, the swell jumps to 4ft from the NW with a period of 8 seconds, and the energy climbs to 208. It’s clean, gentle offshore and the conditions are good. For a spot that’s very consistent, this is the best window we get.

The next day, Wednesday the 29th of July, the morning looks even better on paper: 6ft NW swell, period 9 seconds, and very clean conditions with light cross-off wind. The energy is a solid 599 – that’s strong. This is the biggest, cleanest swell of the stretch, but it’s pushing 7ft, so it’s getting into intermediate territory. The afternoon gets a bit questionable with a cross-shore wind and some chop, so the morning is the call.

After that, we’re back to the wind and chop from the 30th of July through the 4th of August. The swell sticks around at 5ft to 8ft, but the NNW wind is cross-on or onshore again, making it messy. The energy is strong (247 to 917), but with the wind ruining it, it’s not worth it for a paddle. Frankly, that setup with the big swell and strong onshore wind might be more interesting for kite surfing than a surfboard.

So, to sum it up: the first week is a dud. The best on offer is Tuesday afternoon the 28th of July and Wednesday morning the 29th of July. If you can get out then, you’ll get clean, fun waves. After that, it’s back to the waiting game.

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.
