The Rock-Costa Azul Surf Forecast and Surf Report

Alright, let’s talk in feet and miles per hour.

The Rock-Costa Azul is in a quiet stretch right now. We’ve got steady SSW groundswell, but tide issues and light cross-onshore breezes are keeping things from really cranking for the next few days. The combined energy is moderate to strong – 1242 on Monday morning – but the wave report calls it marginal, so you know the tide is messing with the takeoff zone.

Monday 6 July starts clear, with a 4ft SSW swell at a very long 16 seconds, but the cross-on wind from the South at 6 mph puts a little bump on the glass. Afternoon cleans up with a cross-off SW breeze at 9 mph, dropping to 3ft, but still clean.

Tuesday 7 July bumps to 5ft in the morning, 18-second period – that’s proper groundswell energy. Cross-shore wind from the SSW at 6 mph, so a little crossing ripple. Afternoon pushes 5ft with a clean cross-off SW wind at 12 mph. Energy is strong at 1518, but again, marginal. So close.

From Wednesday 8 July through Saturday 11 July, the swell sits between 4ft and 4ft, mostly SSW, periods dropping from 16 to 14 seconds. Winds stay light, mostly cross or cross-off. Saturday afternoon gets a “very good” wave comment – clean, light cross-off breeze – but at 4ft, it’s small. The break sees crowds “often” – you’ll have company, but it’s consistent.

Sunday 12 July to Tuesday 14 July fades to 2ft by Tuesday, but the period jumps to 18 seconds again. Tuesday afternoon is your sneaky call: light SW cross-off wind, clean, “expect very good surf conditions,” energy at 541. For a reef that’s consistent and advanced, that’s a quiet gem. Water temp is about average for the time of year.

Wednesday 15 July and Thursday 16 July are tiny – 1ft to 2ft – with energy down to 232. Not worth the paddle.

Then a gap. Friday 17 July is poor – onshore SE wind at 9 mph, weak 2ft to 3ft. Saturday 18 July and Sunday 19 July spike to 7ft to 7ft of SSW swell, but onshore or cross-onshore wind messes it up. Energy goes to 1353 and 1365, but at 12 to 13 seconds, the wind makes it a chop fest.

Best call of the whole forecast? Monday 20 July. Morning: 5ft SW swell at 12 seconds, light cross-off SW wind at 6 mph, “excellent surf conditions for experienced surfers” – energy 1895. Afternoon: 6ft SSE swell at 12 seconds, offshore West wind at 12 mph, clean, energy 1854. For experienced crew, this is the day. Crowds are “often,” so expect some locals.

Tuesday 21 July still has 7ft SSE swell at 12 seconds, energy 1998, but the morning cross-on South wind at 6 mph and questionable tide mean you’ll want to pick your moment.

So the first week and a half is patchy. Monday 20 July is the clear standout. That’s the one to plan around.

Rusty out.
