The Lowdown
Alright folks, Rusty here. Let’s stare at the charts and see what’s shaking in the region. We’re looking at a 16-day window that starts with a bit of a whimper, not a bang. The first few days are all tiny, blown-out slop with zero score on the quality meter. The winds are up, the swell is down, and it’s a hard pass for a paddle. That’s the story from Saturday the 15th through to the end of that first week, with hardly a ripple to get excited about.
But hold on. Around the 20th of August, there’s a subtle shift. The swell starts to tick up just a fraction, and the wind eases back. Still, the energy is weak and the direction is a bit messy. Honestly, it’s not until the final days of the month that we start to see something with a bit of promise, but even then, it’s a long wait for what’s on offer.
The standout here is Himalayas, a reef setup that’s consistent and exposed to the northwest. The best of the bunch is shaping up to be the Thursday the 27th of August through to the Sunday the 30th of August. The swell isn’t big, sitting around 1ft to 1ft, but it’s coming from the west-northwest with a very long period in the 13 to 15 second range. That’s proper groundswell, and on a reef, that long period should translate into waves with shape and push. The combined energy readings are still on the modest side, hovering in the 50s to 80s, but the quality of the swell direction and period is the real story. The wind stays cross-off or light, and those offshore breezes on some of the afternoon sessions will keep the faces clean. This is a setup that rewards patience and a good eye for a takeoff. The water temp is sitting at a warm 81°, which is pretty much average for the time of year here, so no wetsuit needed.
Crowd warning: this spot can get crowded sometimes, so bring your patience and your best drop-in avoidance skills.
If you’re a beginner, the swell is small enough to be manageable, but the long period and reef bottom mean it’s not a learner’s paradise. For the experienced surfer who knows the lineup, the last weekend of August looks like the only window worth pointing the car at. It’s not a classic, but it’s the best this stretch has to offer.
Rusty.

Information about the Himalayas Surf forecast
The above surf forecast table for Himalayas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Himalayas can be found by selecting the local surf guide option on the grey menu. Our Himalayas 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 (Himalayas) 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 Himalayas 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.
Himalayas is 14 km (9 miles) from Wahiawa. If you plan a vacation in Oahu, look for hotels and other accommodation in Wahiawa. Wahiawa has rooms for a wide range of budgets as well as car hire and transport links.
