Onrus Surf Forecast and Surf Report

Alright, I’m looking at the charts for Onrus, and I’ve got the full 16-day picture. This is a reef break that’s exposed to the SW, and it’s inconsistent by nature, so when it lines up, you’ve got to move. The water temperature is sitting at 60°, which is pretty much normal for this time of year, so no surprises there.

The first solid window opens up on Monday, August 4th. Tuesday morning is glassy, dead calm, with a clean 4ft SW swell at 11 seconds. It’s not massive, but with the wind off the water and the energy reading at 401 (moderate), it’s a fun, user-friendly wave. The afternoon stays glassy with a slight sea breeze, so that whole day is a good one to get wet.

Wednesday, August 5th, is where the real power shows up. The morning brings a 7ft SW swell with a 16-second period, and a clean NW offshore wind of 12 mph. The combined energy hits 1915 (strong). This is proper groundswell, and Onrus being a reef, it’ll handle that long period beautifully. This is the standout of the whole forecast. The afternoon stays clean with a 7ft swell, but the wind picks up to 19 mph, so get out there early.

Thursday, August 6th, is a write-off. The swell jumps to 10ft, which is too big for this spot, and the wind is onshore from the SE. Not worth looking at.

Friday, August 7th, is also unworkable. Swell is 10ft to 12ft, and the wind is cross-onshore. That’s just messy and dangerous.

The weekend, August 8th and 9th, is a mixed bag. Saturday has a 8ft to 8ft SW swell with a cross-offshore wind, so it’s clean but the period drops to 13 seconds. The energy is still strong at 2005. It’s a solid option if you’re experienced. Sunday, though, is a total mess with 25 mph cross-onshore winds and a 10ft to 12ft swell. Kite surfers might be loving it, but for paddle surfing, it’s a no-go.

Monday, August 10th, is more of the same: big, lumpy, and cross-onshore. Not for us.

Tuesday, August 11th, things start to settle. The swell drops to 5ft, but the wind is cross-shore and the period is short at 10 seconds. It’s marginal, but the energy is weak at 767. Not a priority.

Wednesday, August 12th, we get another highlight. The afternoon session is glassy with a 6ft SW swell carrying a very long 18-second period. The energy is 2390 (strong). This is a proper groundswell that will wrap into the reef beautifully. The long period means longer lulls, so the paddle out is easier. This is the second standout of the forecast.

Thursday, August 13th, is similar. The afternoon is glassy with a 7ft SW swell at 15 seconds. It’s clean, powerful, and for the experienced surfer, this is a gem.

Friday, August 14th, is a nice, clean option with a 5ft to 6ft WSW swell, glassy in the afternoon. The energy is moderate at 864. It’s a fun, less intimidating day.

The following week, from August 15th to 19th, the swell stays in the 4ft to 8ft range, with some clean windows. Monday, August 17th, has a morning with a 8ft WSW swell and a NW offshore wind, making it clean and powerful. The afternoon gets too strong at 10ft with a 28 mph offshore, which is hard to paddle into. Tuesday, August 18th, is marginal with onshore winds. Wednesday, August 19th, is back to clean with a 7ft SW swell and cross-offshore winds, a solid end to the run.

To sum it up: the absolute best is Wednesday, August 5th, morning. The second best is Wednesday, August 12th, afternoon. Both are reef-handling groundswells with clean wind. The rest of the period is a mix of clean windows and messy, big days. Don’t sleep on the early mornings.
