The Lowdown

Alright, let’s look at this 16-day window for Strandhill. The first bit is ugly, no way around it.

Starting Sunday the 13th, the surf is clean but small – a 4ft WNW groundswell with a light offshore breeze. The water’s at 60°, a little warmer than normal for September. The combined energy is moderate at 279.

From Monday the 14th through Saturday the 19th, it’s mostly poor. Onshore winds and messy conditions. Tuesday the 15th has a messy 6ft cross-on shore, and by Thursday the 17th the swell hits 10ft but it’s howling onshore and lumpy. The energy jumps to 2954, but it’s all blown out. That’s more for kite surfers than paddlers.

Sunday the 20th is the first real turnaround. Clean 8ft WNW groundswell with a 13-second period and a light cross-off breeze. Over 8ft, so it’s for experienced surfers only. The energy is strong at 2035. Crowds are possible.

But the true standout is Saturday the 26th. The morning brings a 7ft WNW groundswell with a 15-second period – that’s a very long period groundswell. Offshore wind is light, and the energy is very strong at 2047. This is big, powerful, and clean. That long period means longer gaps between sets, and the shape will be excellent. Only for experienced surfers. Sunday the 27th also looks prime with glassy conditions and a 6ft WNW swell carrying good energy at 793.

So, a rough first week, a solid session on the 20th, and then the second week finishes strong with that Saturday the 26th as the one to get excited about. Long-range, but keep it on the radar.

Information about the Strandhill Surf forecast

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