The Lowdown
Alright folks, Rusty here. Let's not beat around the bush: the surf forecast for the next two weeks is a bummer. We're looking at a long, dry spell on our beaches. The first real, rideable waves aren't even popping up on the radar until the end of the month. You're looking at a solid ten-day stretch of knee-slappers and closeouts. It's the kind of lineup where you'd be lucky to get a push, and you'll spend more time just floating than catching anything. There's a glimmer of hope at the end, but you'll need to wait for it.
The spot to keep an eye on is Nantasket Beach. It's a consistent break, but that consistency is showing up as a whole lot of ankle-biters. For the first stretch, we're dealing with swells between 0.3ft and 0.6ft, just an anemic little SE or E bump with a short period and a light cross-shore breeze messing with the surface. The water's a touch cooler than it should be for August, coming in at about 67°, which is a couple degrees below normal, but it's not a shock to the system.
Those first few days are dead. Saturday the 8th is a complete wash, and Sunday the 9th is clean but with zero energy. The rest of that first week is the same story: tiny, weak surf under light, variable winds. We do see a slight bump on Monday afternoon, the 10th, with a 0.4m (1ft) swell, but the period is a terrible 3 seconds, making it look like a mess on the surface. This pattern holds all week. You might catch a clean morning on the 16th with glassy conditions, but the surf is just too small to even bother with.
Finally, on Sunday the 23rd, something shifts. A west-northwest wind swings in, blowing offshore, and the swell finally steps up to a rideable height. The day starts with a 0.8m (3ft) ESE swell, but it's Sunday afternoon that has me interested. The wave energy is still modest, but it's the strongest push of the forecast. The swell edges up to a foot (0.9m) with a 9-second period, and that offshore wind is blowing strong and clean. It will be a proper surf. It won't be huge, but it'll be the one, clear-cut window for you to get out and have some fun. This is the standout of the 16-day run, no question.
So, there's the reality. A long, frustrating wait with one potential nugget of gold at the end. Circle the 23rd on your calendar, and keep the board waxed. Otherwise, find something else to do.
Rusty, signing off.

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

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 Nantasket 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.
