The Lowdown
Alright, folks, Rusty here. Let’s talk about what we’ve got for the next couple of weeks.
Look, I’m not gonna sugarcoat it: this is a tough stretch. For the most part, we’re looking at a long run of messy, blown-out conditions with hardly any decent swell. The wind is the main villain here, coming in mostly from the west and northwest, which puts it in our face or straight across at Machrihanish. For a spot that needs a clean west swell, this is a real kick in the teeth.
We start off on Wednesday the 5th with a fresh 22 mph cross-onshore and a weak 4ft swell that’s just a jumbled mess. It only gets worse that afternoon as a near gale slams in – 31 mph onshore wind with a lumpy 7ft. That’s just nasty. Thursday and Friday are more of the same: small, choppy, and cross-onshore. Not a single thing to get excited about.
The first actual flicker of hope comes on Sunday the 9th in the afternoon. A light 9 mph cross-offshore wind starts to clean things up, and we’ve got a waist-high 4ft swell with a solid 9-second period. The water temp is around 57°, which is normal for this time of year. It’s marginal – a 1 out of 10 – but there will be a few cleanish waves for the patient soul. That’s about as good as it gets for a while.
After that, we hit another dead zone. Monday the 10th through to Thursday the 14th is all small, weak swells with onshore or cross-shore winds. A few clean moments on the 12th, but with swells under two feet, you’d be chasing shadows. Friday the 14th morning shows a chance with a 4ft swell and moderate cross-shore, but it’s not clean.
The absolute standout, and I mean the *only* real standout in this whole 16-day window, is Thursday the 20th in the afternoon. The wind goes glassy – just a 3 mph westerly – and we’ve got a consistent 3ft west swell with an 8-second period. It’s still not huge, but with the sun out and those clean, unbroken faces, it’ll be the best wave of the fortnight. The energy is moderate at 117, which backs that up. A little bit of faith rewarded. Crowds are rare here, so you should have plenty of room.
Before that, there’s a big gap from Sunday afternoon the 9th all the way to Thursday the 20th with nothing worth paddling out for. It’s a long, quiet spell. The rest of the forecast after that stays small and onshore.
So, if you’ve got a board that loves small, clean waves, mark your calendar for Thursday afternoon the 20th. Everything else is a fight against the wind for very little reward.
Rusty.

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