The Lowdown
Alright, Rusty here. Let's break down what Castelejo's got for you over the next couple weeks.
Right off the bat, it's looking bleak. We're staring down a long, dry spell from now through until the 19th of August. The wind is gonna be your worst enemy – howling out of the north and north-northwest, 15 to 22 mph, smashing it cross-onshore or onshore. There's some swell in the water, from 2 ft to 4 ft, with energy all over the place, but it's all academic. The wind is just tearing it up, leaving us with lumpy, choppy, poor surf. Not a single session worth dragging your board out for.
Things finally shift on the 20th of August. The wind drops right off, coming out of the NNE at a light 6 mph. The swell is a solid 5 ft from the NNW with a 7-second period, and the energy is reading 242. It's been a long wait, but that morning is our one real standout. The water's sitting at 66°, which is a bit over 4° colder than usual for August, so you'll want a wetsuit. That light wind is going to make it clean for the first time in ages. The afternoon of the 20th keeps the light wind, but the swell drops back to 4 ft. It's a beach and reef setup, so with the wind easing, it'll be rideable, but temper your expectations.
So, to sum it up: nothing doing until the 20th of August. That morning is your target, but keep in mind it's a long way off and forecasts can shift. The rest? Honestly, you're better off finding something else to do until then.
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.
