Speed, direction and units
Read the selected time, height and unit before comparing places. Near-surface wind is commonly represented at ten metres above the ground. The provider may display metres per second, kilometres per hour or knots; 10 m/s equals 36 km/h.
A northerly wind comes from the north. Animated streamlines describe the direction of flow, but their appearance is not a separate forecast of how fast a particular cloud will move.
Average wind is different from gusts
The wind layer describes a representative wind speed. Brief stronger bursts belong on the gust map. Check both: a moderate average can occur alongside gusts that make an exposed cycle route or a walk beside trees less comfortable.
Buildings, forest edges, hills and narrow valleys alter local wind. Zooming in adds geographical detail but does not turn a model grid into a sensor beside your home.
Coasts, seasons and travel
For a coastal visit or winter journey, compare conditions at departure and arrival. A sheltered town can differ markedly from an open bridge or headland nearby. Read national weather warnings and relevant marine or mountain forecasts when the activity requires them. Revisit the map as the planned time gets closer. An inland forecast also does not replace a marine forecast for an exposed coast or island crossing.
Questions about this map
Why is the wind stronger than the map suggests?
Your location may be exposed, or a brief gust may exceed the representative speed. Terrain and buildings are simplified in forecast models.
Can I compare two models directly?
First match the time, height and units. Different grids and averaging methods can produce different wind values; disagreement is useful evidence of uncertainty.
