WindUp for Surfers

Every other sport here waits for wind. Surfers wait for it to leave. Flip the alarm: WindUp pings you when your break goes glassy or swings offshore — the window worth paddling for.

Surfing Alarm window
Under 8 kt — or clean offshore

Set it once — WindUp rings the second surfing wind hits, even on Silent.

Why surfing

What WindUp does for surfers.

  • Glass alert — ring when the average DROPS below your ceiling
  • Direction filter — only alert when it's offshore at your break
  • Catch the mid-week calm window nobody's watching for

WindUp is a free live wind alarm — set your surfing wind window once and it watches your spot for you, even on Do Not Disturb or Silent.

How much wind

What wind speed do you need for surfing?

Surfing inverts the whole wind question. Onshore wind above roughly 8 knots crumbles faces and turns a good swell to mush; dead calm is glass; and light offshore - about 5-15 knots blowing from land to sea - grooms waves, holds faces open and delays the break. Past 20 knots offshore stops being grooming and starts being a problem: paddling into waves gets hard and spray blinds the takeoff.

Gusts, not just averages

For surfers the gust number is a texture report. A 6-knot average with 14-knot gusts reads calm on paper but puts chop on the face anyway. When the gust and the average sit within a couple of knots of each other, the surface is clean - that's the reading worth driving for.

How to set your surfing alarm

Set WindUp backwards from every other sport: make your MAXIMUM the number that ruins it (say 8 knots onshore), leave the minimum at zero, and add a direction filter for your break's offshore quadrant. The alarm then means one thing - it just went clean at your spot.

Local knowledge

The surfing edge.

The dawn-patrol rule is thermal physics: land cools overnight, the sea breeze dies, and many coasts flip light-offshore until mid-morning. That calm window is movable — a cloudy day can hold it until noon, a hot one can kill it by 8. A live station tells you which day you're getting; the forecast usually doesn't.

Questions

Surfing wind, answered.

Can I use a wind alarm for surfing?
Yes — backwards. Instead of ringing when wind picks up, set a low maximum (say 8 knots) with an offshore direction filter, and WindUp rings when your break goes glassy or offshore. It's a clean-conditions alert, not a wind alert.
What wind is best for surfing?
Under about 8 knots onshore is surfable, dead calm is glass, and light offshore (5–15 knots) is the dream — it grooms the face and holds the wave open longer. Strong offshore past ~20 knots makes paddling in and taking off genuinely hard.
Why do surfers always go at dawn?
Overnight the land cools, the sea breeze dies, and many coasts sit calm or lightly offshore until the land heats up again. That's the glass window. It moves day to day — which is exactly why a live station reading beats a fixed 6 a.m. alarm clock.

Ready when the wind is. It's free.

Set one alarm at your spot. WindUp wakes you up the moment surfing conditions fire.
