Alright, Rusty here. Let’s break down the next 16 days for Sandy Beach. Got to level with you – it’s a rough stretch. Every single session in the whole forecast is marked as poor surf conditions, so we’re looking at a long gap with nothing worthwhile. The water temperature is about normal for the time of year, nothing unusual there, but the winds and swell just aren’t coming together.
Week 1 (July 5th–11th): Starting off Sunday the 5th, there’s a small 3ft SSW groundswell with a very long 18-second period, carrying moderate energy (877). That long-period pulse would usually be a treat at a point or reef, but here at Sandy Beach it’s getting hammered by a 40 km/h (25 mph) cross-shore from the ENE. Instead of clean lines, you get lumpy chop. Monday the 6th jumps up to a 7–8ft ENE windswell, but it’s short period (7–8 seconds) with the same 40 km/h cross-shore – big, messy, and choppy. Wave energy hits strong (1007) but the quality is terrible. This pattern of 6ft to 8ft ENE windswill with cross-shore winds just keeps going all week. With that strong cross-wind and a beach break setup, this looks more like a kite-surfing session than a paddle-surfing one. No standout days here.
Week 2 (July 12th–20th): The second week doesn’t get any better. From Sunday the 12th through Monday the 20th, it’s more of the same: 4ft to 6ft ENE short-period swell, constant cross-shore winds from the ENE or NE at 25 to 35 km/h (15 to 22 mph). Wave energy stays weak to moderate (259–662), but the conditions are consistently lumpy and cross-chop. On the 16th of July, we get a tiny 2ft SSW groundswell with a 16-second period, which sounds promising, but the 30 km/h cross-wind kills it. Nothing is clean, nothing is glassy. The offshore wind direction (NW) never matches the wind we’re getting.
Plain and simple, there’s nothing worth paddling for in this whole 16-day stretch. Sometimes an area goes through a blank run like this where wind and swell refuse to line up. Just one of those times.
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.
