The Lowdown

Right off the bat, the ocean’s got nothing for us. The whole run is a write-off, to be honest. The Breakwater-St Ives is looking at a grim stretch of days where the surf is either too messy, too small, or the wind has it chopped up something shocking.

The first week is a total bust. Monday the 14th has a bit of waist-high west swell at 4ft, but a cross-offshore breeze and a weak 242 combined energy reading means it’s just lumpy mush. Not worth paddling out for. Tuesday and Wednesday see a bit more size, pushing 6ft, but the wind swings cross-onshore and fresh, and the energy spikes to 407 and 1046 respectively. That’s just a washing machine – all power, no shape. Thursday’s the same story, 6ft, but the period drops to 7-8 seconds and the wind keeps it messy.

Friday the 18th throws a bit of a tease. There’s a long-period groundswell pushing through – 13 seconds – with some size at 6ft in the morning, but the wind is cross-shore and the conditions are only marginal. The afternoon cleans up a little with a cross-offshore breeze at 5ft, but it’s still not doing much for me. It’s a “maybe if you’re desperate” kind of day.

The weekend stays flat and forgettable. Saturday’s down to 4ft with weak energy, and Sunday the 20th has a bit of clean vibe with light winds and 4ft waves, but the energy reading is only 349 – weak. Monday the 21st has a clean 3ft with a 12-second period and offshore winds, but it’s just too small to get excited about. Tuesday the 22nd is similar – 3ft, clean, but ordinary.

After that, it just fades. The 23rd drops to 2-3ft, then the 24th has a slight bump to 4ft with a 11-12 second period and clean conditions on Thursday morning, but it’s still not much. The energy is around 358-463, which is moderate, but the swell direction is west and the winds are light cross-onshore. It’s surfable for a longboard, but nothing special. Friday the 25th is smaller again, and the weekend just dies. By the 27th, we’re looking at 1-2ft with weak energy readings of 24-41. There’s literally nothing on the table.

The only faint glimmer is Tuesday the 29th, where a long-period west swell at 14 seconds shows up with 3ft and clean cross-offshore winds. The energy is 398-417, which is moderate, but the size is just too small to call it a standout. It’s a fun little longboard wave if you’ve got nothing else to do, but that’s about it.

Water temp is sitting at 63°, which is a touch warmer than normal for this time of year – nothing crazy, just a bit of extra warmth in the water.

Honestly, mate, the whole 16-day window is a dud. The Breakwater-St Ives is inconsistent, and when it does have something, the winds and conditions are against it. There’s no real standout period here. It’s one of those stretches where you might as well find something else to do. Forecasts can change, but right now, I wouldn’t be holding my breath for a decent session.

Information about the The Breakwater-St Ives Surf forecast

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

The Breakwater-St Ives is 11 km (7 miles) from Camborne. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Camborne. Camborne has rooms for a wide range of budgets as well as car hire and transport links.
