The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for In Betweens over the next couple of weeks.
Right off the bat, I’ll be straight with you – the surf forecast is a bit of a mixed bag. There are periods of solid swell, but the wind is going to be a persistent issue. It’s not going to be a complete washout, but you’ll need to pick your moments carefully.
The water temperature is sitting around 80°, which is bang on average for this time of year. Nothing to complain about there.
The first real window of opportunity kicks off around Thursday the 24th of July. The swell is swinging up, with a 7ft ENE swell on the Thursday morning, but with a short 7 second period, it’s going to be a bit lumpy and weak. The combined swell energy is high at 1031, but that ENE wind is 25 mph, blowing cross-off. It’s clean, but it’s a strong breeze. The quality is marginal, and the size is up over 5ft, so it’s not one for the beginners.
We see a bit of a theme here: the ENE wind is a constant companion. It’s cross-off, which keeps the face clean, but it’s a strong breeze, making it a bit of a battle. The swell sticks around, with 7ft ENE on Friday morning, building to 7ft ENE on Friday afternoon. The energy is up there, hitting 1129 on Friday afternoon, but the period is still short at 7 seconds. It’s a bit of a grind.
The weekend of the 26th and 27th July sees the swell drop off a touch, with 3ft to 4ft from the E and SSE, and the period stretches out to 14-16 seconds. That’s a proper groundswell, but the energy is a bit lower – around 998 to 1112. The wind is still a fresh breeze out of the ENE, so it’s clean, but the waves will be a bit inconsistent due to the long period. For a reef break like In Betweens, that long period can actually be a good thing, giving you those long, walling lines.
The standout for the first week looks to be Tuesday the 28th of July. The swell jumps back up to 7ft from the ENE, with a period of 12 seconds. The combined energy spikes to 1543, which is a solid, powerful push. The wind is a lighter moderate breeze from the NE, still cross-off. This is the best combo of size, power, and clean conditions you’ll see for a while. The 7ft is approaching the "experts only" zone, but for a reef, it’ll be a fun, punchy wave.
Then we hit a rough patch. Wednesday the 29th of July brings a risk of thunderstorms and a cross-on wind from the SE, making it choppy and ugly. The swell is 8ft from the ENE, but the quality is poor. That’s a day to stay on the beach.
The following week (from the 30th of July) is a bit of a gap. The swell drops to 5ft to 6ft, but the wind is back up to a strong or fresh breeze from the ENE. The period is short again, 7-8 seconds. The energy is moderate, between 565 and 741. It’s clean, but the wind is a struggle and the quality is marginal. It’s not really a recommendation.
We get a glimmer of hope on Monday the 3rd of August. The swell is only 4ft, but it’s from the E with a 16-second period. The energy is back up to 1049, and the wind is a moderate breeze from the ENE. That’s a nice long-period groundswell, and the lighter wind means it could be worth a paddle. The swell is small, but the quality is there.
The best call of the entire forecast, if you can wait, is Wednesday the 5th of August. The swell is 7ft from the ENE, with a 12-second period. The combined energy is a solid 1258, and the wind is a lighter 16 mph from the ENE. This is all the ingredients: clean, cross-off, solid size, and good energy. This is the one to circle on the calendar.
After that, the 6th and 7th of August fizzle out with poor conditions and strong winds. So, overall, the best bet is Tuesday the 28th of July for a punchy session, and Wednesday the 5th of August for a promising, powerful swell with lighter winds. The rest of the time, you’ll be battling the seabreeze.
Rusty.

Information about the In Betweens Surf forecast
The above surf forecast table for In Betweens provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at In Betweens can be found by selecting the local surf guide option on the grey menu. Our In Betweens 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 (In Betweens) 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 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. 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.
In Betweens is 4 km (2 miles) from Honolulu. If you plan a vacation in Oahu, look for hotels and other accommodation in Honolulu. Honolulu has rooms for a wide range of budgets as well as car hire and transport links.
