The Lowdown
Alright, listen up. The surf report for Sandy Beach over the next couple of weeks is a story of waiting. The first chunk of it is a write-off. From Tuesday the 8th to the 16th, it's a solid stretch of blown-out, lumpy junk. The wind is mostly cross-shore or cross-on from the ENE and NE, and it's just chopping up whatever swell is there. On the 8th, we have a 8ft SSW swell with a 10-second period, but it's blowing 22 mph from the south, making it a total mess. For days after, the waves are small, mostly under 3ft, and the wind is still ruining the surface.
There's a long gap here, over a week of poor to marginal conditions. You'll be checking the forecast and shaking your head. Then, on Thursday the 17th, things shift. The wind drops way down, swings to the SSE, and the water goes glassy. The swell is small, only 3ft, but it’s a long-period SSW swell at 16 seconds. For Sandy Beach (Bermuda), that long period means it’ll have some energy to it, even if it’s not big. The forecast calls for very good surf conditions. The combined energy is moderate at 532. This is your window. That Thursday morning is the standout, no doubt. The water temp is about normal for this time of year.
The 18th and 19th are still workable with light winds and some decent period in the water, but it's not as clean. After that, the trade winds come back with a vengeance, and it gets messy again. So, to keep it simple: be patient. The first ten days are a wash. The one morning to be out there is Thursday the 17th. It’s small, but it will be the only clean, glassy surf you’re going to see for a while. The break is fairly consistent and can get crowded, so you might want to get out early to get a few clean ones.
Rusty out.

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.
