The Lowdown
G’day, Rusty here. Let’s be straight with you—this stretch is a bit of a mixed bag, and the surf is going to be picky. There’s some real potential hiding in there, but you’ll have to keep an eye on the wind and the tide, because it could just as easily turn to mush as it could turn on.
First thing first, the water’s sitting at 64.2°, which is right on the money for this time of year. Nothing weird happening there. So no need to dig out the extra rubber just yet.
Right now, Tuesday afternoon, we’re looking at a 7.2ft WSW swell at The Three Bears (Oahu), but the wind’s blowing cross-on from the south and it’s choppy. It’s fair, but nothing to get too excited about. The energy reading is 1983, which is moderate wave energy, but the lumpy conditions are holding it back.
Wednesday morning comes in a bit cleaner. Swell drops to 4.6ft, still WSW, but the wind swings around to a cross-off from the ENE at 12 mph. The water cleans up, and you’ll see some decent lines. The energy’s sitting at 700, which is weaker, but the glassier surface will make it more fun for the average surfer. Then Wednesday afternoon is the standout of this first part: only 3.3ft of swell, WSW, with the wind going almost dead—3 mph from the east and glassy. Expect very good surf conditions, but it’s small. You’ll need a longboard for this one. The energy is 569, so weak, but it’ll be smooth.
Thursday’s a bit of a letdown. Morning has 3.9ft with cross-shore winds from the north and a cross-chop. The afternoon gets worse—19 mph from the NNW, lumpy, and barely 3.6ft. Not worth paddling out for anything but a quick splash.
Now we hit the guts of the week. Friday looks messy and blown out. Swell jumps up to 8.2ft in the morning (9-second period, short and chunky) with a strong cross-shore wind at 28 mph. That’s a don’t-bother. The afternoon sees it even bigger at 9.8ft but with 34 mph cross-on winds from the NNW—near gale. That’s blown out, full stop. Saturday doesn’t improve. The swell holds around 9.8ft, with onshore winds all day. It’s a washing machine. The energy is strong—3566 in the morning, 2570 in the afternoon—but with onshore wind, it’s not doing anyone any favors. Honestly, you’d have more fun flying a kite than trying to paddle out. The setup at The Three Bears (exposed reef) with that much swell and onshore wind is more interesting for kite surfing than surfboard riding.
Sunday morning finally gives us a breather. The swell eases to 6.2ft, WSW, and the wind drops to zero—dead glass. Expect very good surf conditions. The energy is 985 (still moderate), but the clean face will make it feel better than the number suggests. That’s a solid session for anyone, from beginners up to experienced. Afternoon brings a light cross-on, but it’s still rideable.
Now, the real standout of this whole stretch. Monday morning the 21st. Swell builds back up to 8.2ft, WSW, with a 15-second period—that’s proper groundswell. The wind’s blowing cross-off from the NNE at 9 mph, leaving it clean. Excellent surf conditions for experienced surfers. The energy

Information about the The Three Bears Surf forecast
The above surf forecast table for The Three Bears provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Three Bears can be found by selecting the local surf guide option on the grey menu. Our The Three Bears 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 (The Three Bears) 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 The Three Bears 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.
