Alright folks, Rusty here. Let’s get into it.
Right off the bat, I gotta be straight with you – this 16-day window for Waimanalo is a total dud. The whole stretch from Tuesday July 7 right through to Wednesday July 22 offers nothing worth paddling out for. Every single morning and afternoon is labeled “poor surf conditions” with a big fat zero score. The trade winds are locked in from the ENE at 22 to 25 mph, blowing straight onshore or cross-onshore, turning what could be a fun little beginner wave into a lumpy, blown-out mess. The swell is coming from the same direction as the wind – ENE – which is not what this break likes. Waimanalo wants NE swell to really line up, but we’re getting ENE at 4 ft to 8 ft with short periods mostly 7 to 8 seconds. That’s weak, wind-affected junk. The combined energy ranges from 244 to 608 – moderate to strong on paper, but that energy is all wasted by the wind. Water temperature is sitting at 79°F, about average for this time of year, so at least you won’t be cold while you’re sitting there watching the mess. But seriously, there’s no hidden gem here. The break is fairly consistent and okay for beginners when conditions cooperate, but when the trades pump onshore like this for two solid weeks, it’s just not happening. A blank run like this is a bit unusual for an exposed spot, but when the wind sets in, it can lock you out for days. Don’t hold your breath – check back after the 22nd. Forecasts can change, but right now it’s a stay-at-home kind of outlook.

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