The Lowdown
G’day, Rusty here. Gonna be honest with you, the next week is going to be a grind. We got a solid pulse of swell coming in, but the wind is going to chew it up and spit it out. For the first full week, from Monday the 14th through to Sunday the 20th, it’s all onshore and cross-onshore, blowing 15 to 35 km/h, turning the ocean into a lumpy, choppy mess. There’s decent size—up to 7ft on Wednesday the 16th with strong energy readings—but it’s all close-outs and whitewater, no shape to it. If you’re thinking of kiting, this is your week; for us paddlers, it’s a write-off.
The water at Constantine Bay (North Cornwall) is 64°, which is a touch warmer than usual for this time of year.
We finally catch a break on Monday the 21st. The wind turns light cross-offshore, and we get a clean, small 3ft wave. It’s ordinary but clean, and a sign of things to come.
Tuesday the 22nd morning is the real deal. It’s dead glassy, no wind, with a clean 4ft of west swell carrying an 11-second period. The energy is moderate, but the conditions are clean. This is the first proper window to get a few good ones, so make that dawn patrol. This is a standout if you can get out before the afternoon cross-shore kicks in.
Then Thursday the 24th is your other day. Light cross-offshore wind, and the swell picks up a touch to around 4ft to 4ft, with that same 11-second period. It stays clean all day. Combined with the offshore flow, this should be the most fun and consistent session of the fortnight. It’s not big, but it’ll be quality.
After that, the swell backs right off. Friday and Saturday are small, and it fades to almost nothing by Sunday the 27th. There’s a hint of a long-period groundswell (14 seconds) on Tuesday the 29th with clean offshore winds, but it’s only 3ft to 3ft and a long way out—promising, but uncertain.
Bottom line: suffer through the first week, then make the most of Tuesday morning the 22nd and all of Thursday the 24th. That’s your best on offer.
Rusty.

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