The Lowdown
Alright, Rusty here. Let’s break down the next couple of weeks.
The first half of the period is a bit of a struggle. We’ve got some swell, but the wind is mostly cross-off from the east-northeast, and it’s not shaping up to be anything to write home about. Water temp is 80°, which is about average for this time of year.
The main break to watch is In Betweens, a reef that’s fairly consistent and beginner-friendly. From Monday the 20th through Wednesday the 22nd, the surf is small and weak – wave heights around 2 ft to 4 ft, with moderate combined energy (559 to 841). The swell is coming from the south or south-southwest, and the wind is cross-off, so it’s clean, but the waves are just too small. Wednesday the 22nd has a 24-second period, a proper groundswell, but with only 2 ft of height, it doesn’t have much punch.
From Thursday the 23rd through Saturday the 25th, the wind cranks up to 22-25 mph, and the conditions turn poor. The swell hits 7 ft on Friday the 24th with a short 7-second period, and the combined energy climbs to 1113, but it’s messy and blown out. Not a good time to be in the water.
The real highlight is Sunday the 26th through Tuesday the 29th. Sunday the 26th brings 5 ft of swell from the east with a 16-second period. The combined energy is strong (1789), and the wind is still cross-off but lighter. By Tuesday the 28th afternoon, the swell builds to 7 ft from the east, with a 13-second period, and the wind drops to 9 mph. The combined energy is 1706. Wednesday the 29th is the best of the lot: 8 ft from the east-northeast, a 12-second period, and only a light breeze of 6 mph. The combined energy is 1795. This is clean, powerful, and well-shaped. It’s a bit big for beginners, but for experienced surfers, this is the window to aim for. The swell direction is on point, and the wind is nearly calm.
After that, it fades out. The end of July and beginning of August is small, windy, and poor.
So, the best bet is Sunday the 26th through Wednesday the 29th at In Betweens. The standout days are Tuesday the 28th and Wednesday the 29th. Don’t miss it.
Rusty.

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 In Betweens 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.
