The Lowdown
Alright, Rusty here again, looking at the same stretch for In-Betweens. It’s a rough patch, no two ways about it. The first week is mostly a bust, with tiny surf and strong winds that’ll have you wondering why you even brought your board.
We kick off on Tuesday, July 14th, with a 3 ft swell from the SSW, period of 14 seconds. That’s a long-period groundswell, but it’s just too small for any real fun. The wind is a cross-off from the ENE at 12 mph, keeping things clean, but the energy is weak. Water temp is 79°, which is right where it should be for this time of year. Barely worth a paddle.
From Wednesday, July 15th, through Sunday, July 19th, the surf is dead. Swell heights hover between 2 ft and 2 ft, with a nasty short-period windswell from the ENE that’s all chop and no shape. Winds are howling at 15 to 22 mph, making it a mess. The scores are all zero: poor surf conditions. The energy readings are moderate to strong, but it’s just wind, not waves.
The first glimmer of hope is Monday, July 20th. The morning brings a 4 ft swell from the ENE, but it’s only 7 seconds—short and weak. The wind is cross-off, and the wave comment says “marginal surf forecast or questionable tide conditions.” The afternoon sees a shift: a 3 ft groundswell from the S, with a period of 16 seconds. That’s a long, clean line, but still small. The energy is a solid 608. This is the first sign of something real.
The best of the whole outlook is Thursday, July 23rd, and Friday, July 24th. The swell is tiny—only 2 ft to 2 ft—but the period is ridiculous: 21 seconds on Thursday morning, dropping to 18 seconds on Friday. That’s very long-period groundswell from the SSW. The combined energy readings are high, from 645 to 709, meaning there’s a lot of deep-ocean push. The wind is a clean cross-off from the ENE at 12-19 mph. For a reef break like In-Betweens, this long period will create some beautifully shaped, glassy waves, but the sets will be spaced out. It’s the highlight of the two weeks, even if it’s not a big swell.
From July 26th to July 29th, the swell builds a bit—3 ft to 4 ft—but it shifts to the E and ENE, with a period of 12 to 16 seconds. The combined energy is very strong, peaking at 954 on the 26th. The wind stays cross-off, so the surface is clean. But the wave comments are all “marginal surf forecast or questionable tide conditions.” On Wednesday, July 29th, the wind drops to a light breeze (3-6 mph), but it’s cross-shore, so expect a few ripples on the face.
Bottom line: your best bet is Thursday, July 23rd, and Friday, July 24th, for that long-period SSW groundswell. It’s not a big day, but it’s the cleanest, most promising window in this 16-day stretch. Keep your eyes on the tide and be patient.
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.
