The Lowdown
Alright, let’s get this straight. The next week and a bit is looking pretty grim for a proper surf, so don’t go getting your hopes up. We’ve got a few tiny pulses of swell, but it’s mostly small and junky. There’s a bit of a wait on our hands.
The outlook kicks off on Thursday the 6th. The swell is a weak 2ft from the west with a short 6-second period, and the wind is blowing onshore from the northwest. It's messy and poor – not worth paddling out for. The water temp is sitting at 66°, which is a touch warmer than usual for this time of year, so that’s a small silver lining.
Friday the 7th is no better. The swell drops right back to a tiny 1ft from the west with a 9-second period. It’s a long-period swell, but there’s just no size behind it. The wind stays onshore. Don’t bother.
Saturday the 8th has a bit of hope early with a light offshore wind from the southeast, but the swell is still only 1ft. It’s clean, but there’s nothing to ride. By the afternoon it goes glassy, but the swell drops to 0.7ft. You’d be floating out there, not surfing.
Sunday the 9th and Monday the 10th are the same story – tiny, short-period waves with cross-onshore or onshore winds. It’s a complete write-off. The combined energy is weak, with values in the 13-39 range. We’re just getting blown out and chopped up.
Tuesday the 11th brings a moderate offshore wind from the southeast, which cleans things up, but the swell is a pathetic 1ft to 1ft. Clean but tiny. You might get a knee-high ripple if you’re desperate.
Then Wednesday the 12th, things start to move. We finally see some proper swell as a 4ft west swell with a 10-second period rolls in by the morning, and the combined energy jumps to a moderate 225. The wind is onshore from the northwest, which will put a bit of chop on it, but there’s finally some push. It’s still poor quality though, so don’t expect much.
Thursday the 13th is when we get the first real chance. The early morning shows a 4ft swell from the west with a 10-second period, and the energy is up to a moderate 290. It’s a bit cross-onshore with a light breeze, making it a bit lumpy, but it’s the most surfable it’s been all week. The break at Whipsiderry (Isle of Man) is fairly consistent, so there should be some sets coming through. This is the first day you might actually get a few waves, though it’s still very average.
The rest of the week rolls along with similar conditions – small swells, onshore winds, and nothing worth getting excited about. The week after that doesn’t show any real standouts either. The surf stays below 4ft and the winds are mostly onshore or cross-onshore. There are a few mornings with light winds and some clean conditions, but the lack of size and power is the main issue.
All in all, the best bet looks like Thursday the 13th, with that modest 4ft west swell. The energy is moderate, the period is decent, and even though the wind isn't perfect, it's the best of a bad bunch. The swell direction from the west is spot on for Whipsiderry, which is exposed to the west-northwest. But honestly, it’s not going to be a day to remember.
After that, the outlook goes flat again, with a serious gap in quality surf for the following days. We are looking at a pretty barren run until at least the 20th, and even then, it’s just a consistent onshore wind and 4ft to 4ft of mediocre swell. The water temp will be around average for that time of year.
So, keep the wax in the car, but don't rush to the beach. It’s going to be a waiting game. Forecasts change, though, so keep an eye on it.

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