What makes a sailing day
Wind in your band
The sweet spot depends on your craft: pick a profile — Beginner/Kayak (3–10 kt), Cruising (6–16 kt), or Performance/Wing (8–22 kt) — and every score on the site retunes itself.
Gust factor
Gusts more than 1.5× the sustained wind mean jibe-crashing holes and sudden knockdowns — the score dings them hard.
Storms & cold
High rain probability is treated as thunderstorm risk, and cold air raises the stakes of a swim. Both subtract from every affected hour.

All guidesThermal winds: why lakes breeze up every afternoon
The reliable afternoon lake breeze is a heat engine you can set your watch by.
Gust factor: the number that predicts jibe crashes
Sustained wind tells you how fast you'll go. Gust factor tells you how often you'll swim.
Reading OPW (Office of Public Works) gauges: what the level number means
Metres above a station datum — knowing what your gauge reports prevents bad launch decisions.
How the LakePulse Ireland sailing score works
A 0–10 rating built from wind, gusts, storms, and cold — and tuned to your kind of sailing.
Why wind direction matters more on lakes than at sea
The same wind speed is a completely different day depending on where it comes from.
Met Office warnings and when to stay ashore
What the warnings actually mean, and how to make the go/no-go call for your boat.
Questions
Where does the data come from?
Water levels come from the Office of Public Works (OPW waterlevel.ie real-time hydrometric network), updated every 15 minutes. Wind forecasts come from Open-Meteo, blending Met Éireann, ECMWF, NOAA GFS, and DWD ICON models. Everything is open public data, refreshed continuously.
What is the sailing score?
A 0–10 rating for every hour: full marks for steady 6–16 kt wind, minus penalties for big gust factors, rain/thunderstorm probability, and cold air. It is tuned for dinghies, small keelboats, windsurfers, and wing foilers.
Does it cost anything?
No. LakePulse Ireland is free, has no account requirement, and works on any phone or laptop browser.
