The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Kennack Sands.
First off, the honest truth: we’ve got a long, dry spell ahead. For the first two weeks of August, it’s looking like a write-off. From Monday 3rd August right through to Monday 17th August, there’s barely a ripple to get excited about. The swell is tiny – often less than 1 ft – with periods that are short and weak, or long-period ghost swells that just don’t have any push. The energy is in the single digits or low teens at best, and a lot of the time it’s flat (0). The wind is a mixed bag of cross-shore, cross-onshore, and offshore, but without any swell, it’s just a nice day for a swim. There’s a gap of about two weeks with no real surf to speak of.
Now, for the one and only standout. Mark your calendars for Tuesday 18th August. We finally get a pulse of life. The morning shows a clean, moderate offshore wind from the NW at 12 mph, which is a major positive. The swell bumps up to 5 ft from the E, with a period of 6 seconds. The combined energy hits 128, which is moderate wave energy. It’s not a world-beater, but after two weeks of nothing, this is the best we’ve got. The break is Kennack Sands, a sheltered, inconsistent spot that’s best for beginners. Keep in mind it’s inconsistent, so patience is a virtue. The early wind will keep the surface clean, but don’t expect perfection. It’s surfable, but ordinary.
Water temperature is about average for the time of year, so no surprises there.
Stay patient, folks. The long wait might be over, but it’s not a classic.
Rusty.

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