The Lowdown
Alright, let’s talk surf. This stretch at Disappearing Sands (United States) is mostly a tease—real flat for long stretches, but there’s one glassy window that might just save the week. Water’s about 82°F, which is roughly 2°F warmer than normal for this time of year—feels like a warm bath. You’ll be fine in boardshorts.
Tuesday morning the 8th: There’s some size—7ft from the west with an 11-second period, and the combined energy is strong at 2103, but the wind is a cross-shore 25 km/h out of the south. The comment says marginal, and this spot is inconsistent anyway. Too choppy to be fun. Tuesday afternoon eases to 5ft, wind drops to 15 km/h cross-shore—still a mess.
Wednesday the 9th through Sunday the 13th: Total dead zone. Swell drops below 3ft, periods get long (14-16 seconds), but the energy is weak—combined values in the 200-400 range. Winds are light but mostly cross-onshore or onshore, with rain and thunderstorms. Don’t bother. This is a gap of five days where you’re better off doing anything else.
Monday the 14th to Tuesday the 15th: Still tiny—1ft to 2ft, with very long 20-23 second periods, but energy is weak (around 215-369). Light onshore winds. Not breaking worth your time.
Now, the one real standout: Wednesday the 16th afternoon. The swell is only 3ft from the SSW, period 18 seconds, and combined energy is 422—weak to moderate. But the wind goes glassy, and the comment says “expect good surf conditions.” For a spot this inconsistent, that’s gold. This SSW groundswell will wrap in clean, small but rideable, perfect for beginners. That’s your pick of the whole run. The same glassy conditions come back on Thursday the 17th afternoon (2ft, SSW, 19s) and Saturday the 19th afternoon (2ft, SSW, 15s)—both glassy, worth a paddle if you’re local.
After that, from the 20th to the 23rd, it’s back to marginal. Small swells, weak energy, and onshore or cross-onshore winds. The 23rd has a little bump (202 energy) but the wind is onshore. Nothing special.
So here’s the deal: the only true standout is Wednesday the 16th afternoon—and that’s if tide and glass align. It’s not big, but it’s clean, and for a break that rarely works, that’s a win. The rest is a long wait, especially that flat stretch from the 9th to the 13th. Stay patient, keep the board waxed. Rusty out.

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