Alright, Rusty here. Let's get into it.
We're looking at Halfpoint/Fullpoint in the Big Island area. I gotta be straight with you, the next few weeks are looking pretty grim. We've got a long stretch of poor conditions ahead, starting from Saturday, July 11th all the way through to Friday, July 24th. That's a solid two-week gap where you'd be fighting a losing battle.
The main culprit is a consistent, strong cross-shore or cross-onshore ENE wind that's just going to chop everything up. For the first week especially, from the 11th to the 18th, we're looking at wind speeds of 19 to 28 mph. That's a lot of breeze, creating messy, lumpy cross-chop. The swell energy is mostly moderate, with readings in the 300s and 400s (737, 485, 428), but the wind is just ruining it. The water temp is about average for the time of year, nothing unusual there.
The swell direction is almost entirely ENE, which isn't ideal for this spot's optimum ESE direction. The swell period is short, around 7 to 8 seconds, meaning weak, wind-affected waves. There's no standout here for a long, long time.
The only sliver of hope, and I mean a sliver, comes on Saturday, July 25th. The morning session sees a marginal forecast, with the wind finally dropping to a moderate breeze from the NE at 16 mph. The swell will be a middling 5 ft from the ENE with short period. The combined energy is moderate at 512. Don't expect glory, but it's the only window where you might find a half-decent wave. The crowds are "often" here, so don't be alone. But honestly, with that still being cross-shore and lumpy, I'd keep expectations low.
Nothing else comes close. The whole month is a washout for quality surf. Keep checking back, things can change.

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