Alright, Rusty here again, same story but in feet, miles, and Fahrenheit for you.
We’re looking at Roca Alta over the next couple weeks. It’s an advanced reef break, exposed to the swell, and it loves a NE direction. Water temp is about normal for this time of year, nothing out of the ordinary.
First surf comes Friday morning, July 3rd. Clean 7ft swell out of the ENE, 9-second period. Wind is light offshore from the SW, glassy as can be. Combined energy is moderate at 674. This is a real good start. Very good surf.
Saturday the 4th gets cross-shore and cross-onshore winds, surf around 6ft to 6ft, but it’s choppy and messy. Not worth paddling out.
Sunday the 5th morning cleans up with a lighter cross-offshore breeze and a 5ft swell. By afternoon it’s glassy with 4ft. Small but tidy.
Monday the 6th is small and onshore. Skip it.
Tuesday the 7th through Saturday the 11th is a long run of marginal conditions. Swell sticks between 6ft and 7ft, but the wind is mostly cross-on or onshore. Lots of ripple and chop.
Then we get to Sunday the 12th of July morning. This is the one. Glassy conditions, 8ft of ENE groundswell with an 11-second period. That’s a long period pulse hitting this reef perfectly. Energy is strong at 1192. This is for experts only – over 8ft is serious size. If you’ve got the skills, this is your standout session.
Monday the 13th morning is also excellent. Glassy again, 7ft swell, energy at 1003. Slightly less than Sunday but still top-tier. The afternoon goes onshore.
Tuesday the 14th offers a clean morning at 7ft and a clean afternoon with a cross-offshore breeze. Two good windows.
Wednesday the 15th onward gets wind-affected. By Thursday the 16th, we see a bigger 8ft push but the wind is cross-on – big and bumpy, expert-only and not at its best.
Friday the 17th and Saturday the 18th drop back toward 6ft to 7ft but stay messy with cross-shore chop.
Your top call? Sunday the 12th of July morning. Roca Alta with clean, powerful groundswell. Monday morning the 13th is your backup. Crowds are possible when it’s this good. Don’t miss that Sunday.
Rusty.

Information about the Roca Alta Surf forecast
The above surf forecast table for Roca Alta provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Roca Alta can be found by selecting the local surf guide option on the grey menu. Our Roca Alta 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 (Roca Alta) 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 Roca Alta 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.
