The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin' over the next couple of weeks.
To be straight with you, this is a tough one. The forecast is basically a long stretch of “poor surf conditions” with very little to get excited about. We’re looking at Harlyn, and it’s a sheltered spot that needs a very specific window to work. The first recommendation isn’t until the 23rd of July, and even then, it’s a tough sell.
The water temperature is sitting at 64°, which is a touch warmer than normal for this time of year, so at least you won't be freezing while you’re waiting for a wave.
Let’s start with the 23rd of July, Thursday morning. We’ve got tiny 2ft swell from the NNW with a short period of 6 seconds, and the energy is weak (55). The wind is glassy from the north, which is a positive, but the swell is just too small and weak to do anything with. It’s a clean, flat-looking pond. Thursday afternoon the wind picks up to 12 mph onshore, making it worse.
Friday the 24th is even smaller, with 1.0ft and 0.3ft waves. Forget it.
Saturday the 25th sees a little bump in size, 2ft in the morning and 4ft in the afternoon, but the period is 4-5 seconds – that’s junky wind swell. The wind is cross and cross-on, 12-19 mph, making it choppy and lumpy. The energy is weak (90). Not worth paddling out.
Sunday the 26th is the biggest swell of the whole window, with 7ft from the WNW and a period of 7 seconds. The combined energy jumps to moderate (426-433). However, the wind is a stiff 19-22 mph cross-onshore, making it a lumpy, windy mess. That energy is getting churned into a washing machine. For a beginner spot like Harlyn, this is too big and messy anyway. For a more experienced surfer, the wind is just ruining it.
The 27th to the 29th of July see a drop back to 1ft to 3ft, with mostly onshore or cross-onshore winds. The only spark of hope is the morning of the 28th of July, Tuesday. We get a light offshore wind from the SSE at 3 mph, clean conditions, and a 2ft swell from the west with a 9-second period. The energy is weak (56). It’s a tiny, clean, glassy morning session for a longboard or a foamie, but you’ll be scratching for waves.
The 30th of July through to the 2nd of August offer a bit more size on the 2nd of August with 5ft swell from the west (223 energy) and a 7-8 second period, but the wind is cross-onshore in the morning, switching to a clean cross-offshore in the afternoon on the 2nd. That afternoon might be the best of a bad bunch, but it’s still not great.
After that, the first week of August is back to tiny, weak waves.
The one standout? Honestly, there’s no true standout. The closest thing to a decent session is the morning of the 28th of July, with that clean offshore wind and 2ft west swell. It’s a beginner’s dream of a clean, small wave, but it’s inconsistent. If you’re desperate for a paddle, that’s your window. The 2nd of August afternoon has a bit more power, but it’s not clean in the morning.
This is a long stretch of poor surf. For a spot like Harlyn that’s inconsistent anyway, a blank run like this is pretty normal. The forecasts can change, but right now, it’s looking grim.
Rusty.

Information about the Harlyn Surf forecast
The above surf forecast table for Harlyn provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Harlyn can be found by selecting the local surf guide option on the grey menu. Our Harlyn 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 (Harlyn) 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 Harlyn 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.
Harlyn is 6 km (4 miles) from Padstow. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Padstow. Padstow has rooms for a wide range of budgets as well as car hire and transport links.
