Alright, Rusty here. Let’s size this up.
This stretch is a tough one, no two ways about it. We're only looking at In Betweens, and the story is all about that stubborn cross-off wind from the ENE. It blows at 19 to 25 mph for most of the period, and while it keeps the surface looking clean, the swell never lines up with what this reef wants. The guide says this spot loves swell from the SSE, and we almost never see that.
Right out of the gate, Sunday the 12th and Monday the 13th, we've got decent size, about 6 ft, but it's short-period windswell at 7 to 8 seconds. The combined wave energy is high, over 700, but the reports say "poor surf conditions." It’s a lot of water moving, but not a lot of shape. You’d be fighting a strong breeze and just getting chopped.
That poor run is the theme. The surf drops to about 2 ft by the 15th, and while it switches to a SW groundswell with a nicer 13-14 second interval, it’s too small and the wind is still howling. For a good long stretch, from the 12th through to the 22nd of July, you’re looking at a blank run. There’s barely a session worth mentioning. On the 19th you get a bump back to 5 ft from the ENE, but it’s back to that short period and fresh wind. No dice.
The only light at the end of this tunnel is the last weekend. By the 26th and 27th of July, we see a proper S and SSW groundswell roll in with a long period of 15-17 seconds and heights around 3 ft. The combined energy hits 892, meaning real power. The wind is still strong from the NE at around 19 mph, but it’s cross-off. For a reef break, that long period stuff can hold up if you're in the right spot. It’s clean, but it’s tiny.
With the persistent wind, this setup leans more toward kite surfing than paddle surfing for the vast majority of the window. The one standout would be that final weekend, but it’s two weeks out, so keep your expectations in check. The board stays in the car for now.

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.
