TL;DR: No single app wins. Windy has the best map and model comparison. Windfinder has the most spots. iKitesurf has the most kite-specific data. But none of them wakes you up when your beach fires. The workflow most riders settle on: plan with Windy or Windfinder the night before, then let WindUp ring you live — even on Do Not Disturb — the moment your wind range hits.
“What’s the best wind app for kitesurfing?” is the most-asked question in r/Kiteboarding, and the answers are always a pile of app names with no structure. So we tested the five that actually come up — Windy, Windfinder, iKitesurf, PredictWind and WindUp — across kite beaches over a full season, and sorted out which job each one is actually good at.
The short version: forecasting and alerting are two different jobs. Most apps do the first. Almost none do the second.
The two jobs a kitesurfing wind app has to do
- Forecast — tell you tomorrow whether it’s worth planning a session. This is a model problem (ECMWF, GFS, ICON) and a UX problem (can you read it fast?).
- Alert — tell you right now, the moment your spot crosses your wind range, so you don’t sit refreshing the forecast all morning and miss the window.
Every app below is great at one of these. The mistake riders make is expecting one app to do both.
Quick comparison
| App | Best at | Live alarm | Free tier | Verdict |
|---|---|---|---|---|
| Windy | Map UX, model comparison | ❌ none | ✅ generous | Best for planning |
| Windfinder | Spot coverage (160k+) | ❌ none | ✅ good | Best for spot variety |
| iKitesurf | Kite-specific data | 🔒 Premium only | ⚠️ limited | Best for data nerds |
| PredictWind | Offshore / departure | ❌ none | ⚠️ limited | Best for passage planning |
| WindUp | Live wind alarm | ✅ free, cuts DND | ✅ full | Best for catching the session |
Windy — the best for planning
Windy.com is the most-recommended app in the kite community for a reason: the animated map is the best in the business, and you can flip between ECMWF, GFS, ICON and NEMS to see whether the models agree. When they do, conditions are likely. When ECMWF says 22 kt and GFS says 14 kt, you’ve learned something too — it’s uncertain, don’t book the day off.
Where it falls short for kiting: Windy is a forecast app. It never tells you the wind is blowing — you have to keep checking. There’s no live alarm at all. Great the night before, useless at 9 a.m. when you’re deciding whether to drive to the beach.
Windfinder — the best spot coverage
Windfinder has 160,000+ forecast spots, so your obscure local beach is probably in there with a superforecast and, often, a live measurement station nearby. Solid mobile UX, tide and wave data on top.
Where it falls short: same core gap — no live alarm. The Plus tier unlocks more data but still won’t ring your phone when the wind arrives.
iKitesurf — the most kite-specific
iKitesurf is built for kiters, hooked into the Tempest weather network (65,000+ proprietary stations), with a kite-tuned interface. If you live near a Tempest station, the live data is excellent.
Where it falls short: the alarm and the best live data are Premium only. You’re paying a subscription for the one feature that should be table stakes.
PredictWind — the best for offshore
PredictWind is the racing/offshore standard, with proprietary PWG and PWE models and departure planning. If you’re doing downwinders or planning a crossing, it’s worth the (steep) $190–330/yr.
Where it falls short for everyday kiting: overkill and expensive for “is my local beach on?” And — you guessed it — no live alarm that cuts through Do Not Disturb.
WindUp — the one that actually wakes you up
Here’s the gap every app above leaves open: none of them rings you when your spot fires. You set your wind range, your gust ceiling and your direction filter, and WindUp alarms you the second live readings cross your threshold — even when your phone is on silent or Do Not Disturb. It’s the only fully-free app with a live alarm.
It’s not trying to replace Windy’s map. It’s the app you set after you’ve planned with Windy, so you can stop refreshing and go live your life until your beach is actually on. See the kitesurfing setup guide for the exact min/max/direction config.
So what should you actually install?
For most kiters, the honest answer is two apps:
- Windy or Windfinder — to plan the night before and read the model agreement.
- WindUp — to catch the session, alarm-driven, free, no subscription.
If you only install one and you already know your local spot, install the one that solves the problem you actually have at 9 a.m.: not “what’s the forecast?” but “is it on right now?”
How to set your kite wind alarm
- Pick the live station closest to your home beach.
- Set your wind range — most riders run 15–25 kt; adjust for your weight and quiver.
- Add a gust ceiling so you’re not alarmed into a session that’s overpowered.
- Add a direction filter — only alert when the wind is on-shore or side-on, never offshore.
- Put the phone down. WindUp rings when it’s on.
