Table - best surf conditions forecast for Anaehoomalu Bay_A-Bay over the next 16 days.
G’day, Rusty here. Grab a coffee because we’ve got a long stretch ahead, but the honest truth is that for this corner of the coast, the next 16 days are a real struggle. There’s surfable waves on offer, but nothing that’s going to get your heart racing. We’re looking at a classic lean spell, so don’t hold your breath. The first few days are a total write-off with tiny, poor quality waves, and the real action—if you can call it that—doesn’t show up until the second week. Let’s break it down.
The first few days, from Thursday the 9th of July right through to the end of the weekend on the 12th, are a write-off. We’re talking ankle-snappers, 0.7ft to 1ft, with a mix of cross-on and cross winds that are doing nothing for the surface. The combined energy is weak, mostly in the teens (17 to 112), and the surf is just not there. No point even looking at the beach.
Monday the 13th and Tuesday the 14th are still very ordinary. The waves are a bit bigger but still below waist-high, and the energy is still low. The one tiny glimmer comes on Tuesday afternoon, when the wind drops to glassy and the swell ticks up to 2ft, but the combined energy is still only 198—moderate at best. The conditions are “surfable but very ordinary,” which is code for “don’t paddle out unless you’re desperate.” Crowds are possible at Anaehoomalu Bay (A-Bay), and it’s a consistent reef and point break, but there’s nothing to get excited about.
Now, here’s the standout—and it’s the only real highlight of the whole outlook. Wednesday the 15th of July is the best day. Both morning and afternoon see glassy conditions with a clean 3ft swell from the west, riding a long 15-16 second period. The combined energy jumps to 310, which is solid moderate wave energy. The wind is a light offshore/northwest or glassy, so the waves will be clean and lined up. This is the day to paddle out. It’s still small, so it’s good for all levels, but the quality is there. Crowds are possible at a spot like A-Bay, so get in early. The water temperature is about average for this time of year, so no need for a thick wetsuit.
After that, things drop off fast. Thursday the 16th is still surfable with 2ft to 3ft, but the wind turns cross-shore and the energy drops to 218-294. It’s not terrible, but it’s not special. Friday the 17th through to the end of the outlook on the 24th of July fades away. The swell drops back to 2ft and below, the energy tanks into the 0 to 100 range, and there are even days with no swell at all. The wind is a mix of cross and glassy, but the waves are just too small to bother with.
So, the net is this: there’s a long gap of junk surf from the start until the 14th, then a single decent day on the 15th, and then silence again. If you’re a kite surfer looking at the beach setup, those days of 2ft to 3ft with cross-shore wind might be more interesting, but for a paddle surfer, the only real option is Wednesday the 15th. Keep an eye on the forecasts, because it tends not to stay this flat forever, but for now, this is a rough run.
Rusty.
