Windy.app's guide to weather

⏱ ~7 min · 9 expert tips inside

Windy.app helps you decide when to go out (and when not to) using wind and weather forecasts for your exact spot.

In this guide, you'll learn to:

  • Check the weather in under a minute
  • Understand what you see
  • Make better decisions

1. Start in 60 seconds

Check where and when to go out in under a minute.

1) Find a good spot

If you need steady wind, start with the wind color scale and look for that color on the map.

Finding a good spot

If wind isn't that important — check gusts, rain, swell, water temperature, or add overlays like fog and fronts.

2) Open the detailed forecast

Start with the basics — wind, gusts, and rain. Check more details if needed — waves, currents, temperature.

3) Compare models (optional)

Each model gives a slightly different forecast. Comparing them shows how reliable it is.

Comparing models
🌤

Meteorologist tip: If models agree → higher confidence. If not → expect uncertainty. Postpone, choose another spot, or wait for the next update (~6 hours).

💡

After you do this a few times, reading a forecast becomes fast and intuitive.

2. Right before you go: 3 quick checks

⚠️

Real-life conditions can change faster than the forecast updates. These three quick checks help you make safer decisions.

1) Rain radar check

  • Radar shows real rain now (not a forecast) within ~100–200 km.
  • Windy.app adds a short 2-hour forecast (nowcasting).
  • Tap Play to see how rain moves.

Cold front
🌤

Meteorologist tip: A long, fast-moving rain band is often a cold front — wind shift, stronger gusts, thunderstorms, temperature drop after passage.

2) Live wind (weather stations) check

  • Weather stations show real wind and gusts — not a forecast.
  • The forecast can be wrong. Stations show reality.
Weather station

How to read live wind:

  1. Does it match the forecast?
  2. Is it increasing or dropping?
  3. Check gusts — they can be a game-changer.
💡

The nearest stations are just below the forecast table:

3) The freshest forecast check

Check which model was updated last (shown under the forecast table). Has it changed?

Latest forecast

When timing is important, switch from a 3-hour step to a 1-hour step for easier planning.

1-hour step
🌤

Meteorologist tip: Fresh forecasts include the most recent observations — in fast-changing weather, this can make a real difference.

4) Live wind screen

  • Real data, not a forecast
  • Confirms or adjusts your forecast
  • Shows trends (building or dropping wind)
  • Tells you when wind is finally what you need
💡

Set up for faster reading: Add spots and stations to Favorites. Customize the Spot Forecast table. Use weather overlays for context (fog, thunderstorms, fronts, isobars).

4. Weather models — key to accuracy

Windy.app has 15+ models — the best in the world. Why check more than one: agreement = confidence; disagreement = be cautious.

  1. Start with ECMWF (best overall).
    ECMWF
  2. For more accuracy — use Best model mode.
    Best model
    🌤

    Meteorologist tip: "Best model for this spot" = matched the wind here best in the last 10 days. The "best" model may change.

  3. Check local or regional models too — they capture coastal, mountain, and valley effects better.
    Regional models
  4. For confidence, compare all models.
    Compare
🌤

Meteorologist tip — compare models especially when:

  • Wind or rain is close to your go/no-go threshold
  • Storms are possible
  • Forecasts change a lot between updates
🌤

Meteorologist tip — do a quick post-check:

Compare 10 days
Compare station
  • Which model was closest?
  • Was timing wrong, strength wrong, or both?

Pick those models next time for this spot.

✓ You're now thinking like a meteorologist.

Meteorological terms

Wind direction: Where wind blows from. "North wind" blows from north to south.

Gusts: Short peaks in wind speed — often decide whether conditions feel manageable.

Radar: Real precipitation right now, not a forecast.

Nowcasting: Short-term estimate based on recent observations (often used with radar).

Weather station: Live report of wind, gusts, and direction at a real location.

Front: Boundary between air masses. Linked to wind shifts, showers, and fast changes.

Isobars: Pressure lines. Tighter spacing = stronger wind.

Wave height: How big the sea is expected to be.

Wave period: Time between waves. Longer period = more powerful waves.

Wave direction: Where waves come from — changes which spots are exposed.

Sea / land breeze: Local winds from land–water temperature difference. Build during the day, weaken after sunset.

Local winds: Driven by terrain, heating, or cooling. Can differ a lot from the regional forecast.

Wind shadow: Weaker-wind area behind an obstacle. Lighter and gustier near the edges.

Tunnel effect: Wind speeds up through narrow gaps (passes, straits, valleys). Expect stronger winds and sharper gusts.

Global model: Worldwide coverage, lower detail.

Regional model: Smaller area, greater detail.

Resolution: How detailed the model grid is. Smaller km = more local detail.
