The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.

Right off the bat, we’ve got a bit of a rough patch. The first few days are looking pretty grim for a proper paddle. Through Monday and Tuesday, the wind is a pain, mainly cross or cross-on, and the wave quality is just poor. The water temp is about average for this time of year, so nothing special there.

The first real glimmer of hope comes on Wednesday the 22nd in the afternoon. Sandy Beach is showing a 5ft swell from the ENE with a period of 11 seconds, and the combined energy is moderate. The wind is still cross, but it’s not as messy. It’s a marginal call, but if you’re desperate, that’s your window. It’s a beach and reef setup, so on a bigger day like this, it’s more for the intermediate crew.

We slog through Thursday and Friday with more strong, messy wind and poor surf. Friday afternoon the 24th sees some size (8ft from the ENE), but with a short period of 8 seconds and a strong cross-shore wind, it’s just a lumpy mess. If you’ve got a kite, that’s more interesting than a paddle board.

The real standout, the one worth circling on your calendar, is the weekend of the 26th and 27th. Sunday the 26th morning, we’ve got a 5ft swell from the E with a period of 16 seconds. That’s a very long period groundswell, and the energy is strong. The wind is still cross, but it’s a fresh breeze, not a gale. This is going to be a pack of energy, and for a point break or a reef, this could be proper. The sets will be fat and lined up, and the long gaps between them make paddling out a bit easier. It’s a fairly consistent spot, so crowds are likely, especially with a swell like this. The direction is E, which is close to the optimum ESE, so it should wrap in nicely.

Then on Monday the 27th, we’ve got a similar story: 5ft to 6ft from the E, period 14 seconds, still strong energy. The wind is cross, but it’s manageable. This is the best run of the whole outlook.

After that, it fades off. The 28th is still ok, with 5ft to 5ft from the E, but the energy drops. Then from the 29th onwards, it’s back to marginal or poor conditions, with the wind picking up again. The 31st and into early August, the swell drops right off, with small waves (2ft to 3ft) and onshore winds. It’s a real dead run for the second week.

So, if you’re keen, the 26th and 27th are your best bet. That groundswell from the east with that long period is your ticket.

Rusty.

Information about the Sandy Beach Surf forecast

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

Sandy's Beach is 15 km (9 miles) from the city of Kailua. If you plan a vacation in Oahu, look for hotels and other accommodation in Kailua. Kailua has rooms for a wide range of budgets as well as car hire and transport links.
