Blue Ocean Surf Forecast and Surf Report

Alright, let’s get into it. The next couple of weeks are looking good for those who can handle some size. The big story is a solid, long-period SSW groundswell that’s about to hit, and it's going to be pumping at Blue Ocean.

We kick off on Wednesday, August 19th, with Blue Ocean coming alive. The swell is 7.9 ft from the SSW with a very long period of 18 seconds, and the combined swell energy is a massive 3637. This is serious groundswell—perfect for a point or reef setup. The water temp is sitting at 79.3°, which is right on the money for this time of year, so no surprises there. The morning has a clean cross-off breeze from the SE at 9 mph, keeping things glassy. This is a standout session for experienced surfers. The afternoon holds at 8.2 ft, though the wind picks up a bit to 12 mph, still cross-off, but the conditions get a bit more marginal.

Thursday, August 20th, is more of the same on the surface: 8.2 ft in the morning, 7.9 ft in the afternoon, both from the SW with a period of 16 seconds. The energy is still high, 3522 in the morning. The wind stays cross-off, so the waves should be clean. However, the forecast flags marginal conditions, likely due to the tide or shape. Still a solid option for the experienced crew.

By Friday, August 21st, the swell drops a little, but the morning has a 4.6 ft wave with a 18-second period—another long-period groundswell. The energy is 2622. The wind is cross-off. It’s a bit smaller, so it might be cleaner for intermediate surfers, but the long period will make it powerful. The afternoon sees a jump back up to 7.5 ft.

Saturday, August 22nd, and Sunday, August 23rd, the swell is holding around 5.9 ft to 7.2 ft, with a 16-second period. The wind is still cross-off but stronger at 12-16 mph. The energy is dropping, but it’s still in the moderate range. The quality is solid, though the conditions are getting a bit more challenging.

Monday, August 24th, through Tuesday, August 25th, the swell is steady at 5.6 ft to 6.2 ft from the SSW. Period holds at 16 seconds. Energy is dropping into the 1700s. The wind is cross-off, but the reports are mostly marginal. It’s still surfable, but the best of the run is behind us.

Then we hit a bit of a lull. Wednesday, August 26th, to Thursday, August 27th, the swell drops to 5.2 ft, then 2.6 ft. The energy plummets to 628. The period is still long at 16 seconds, but the lack of size makes it less interesting. The wind on Thursday afternoon switches to a light cross-shore, 9 mph, with a 20-second period—that’s a very long period, but only 3 ft, so it’s going to be a slow, clean day for a longboard or a sunset paddle.

Friday, August 28th, the swell comes back hard: 7.9 ft in the morning from the SSW, period 16 seconds, energy 2856. But the wind is a light cross-onshore from the S at 3 mph. This will create some small wind ripples, so it’s not as clean as previous days. The afternoon is similar, 7.5 ft with a cross-shore, but still a bit chopped.

The weekend of August 29th–30th sees the swell drop to 5.2 ft–6.2 ft, with a shorter period of 13 seconds. The wind is cross-onshore, making for a choppy, messy weekend. The energy is moderate, around 1151. Not the best window.

But hold on. Monday, August 31st, is a standout. The morning has 4.3 ft from the SW with a very long period of 18 seconds. The energy is 1377. The wind is cross-off at 9 mph, and the report says "excellent surf conditions for experienced surfers." This is a clean, glassy morning with a classic groundswell. It’s smaller, but the quality will be high.

The absolute best of the outlook is Tuesday, September 1st. The afternoon session is a 7.9 ft SW swell, period 17 seconds, energy 3261. The wind is cross-off at 9 mph. The report flags this as "excellent surf conditions for experienced surfers." This is the pick of the litter. Big, powerful, clean waves. The morning is also very good, with 7.5 ft and a score of 4.
