Does WeatherNext 3 forecast wind at 100 m?

Yes. WeatherNext 3 includes 100 m wind, a height commonly used for turbine planning. Most surface grids are around 10 km, so the field is useful for regional planning rather than a turbine-specific control decision.

Can WeatherNext 3 replace site wind measurements?

No. Use the model to plan ahead and local measurements to verify what is happening at the site. Wind speed, direction and turbulence can change sharply across terrain below the grid scale.

How far ahead is the wind forecast useful?

The first hours to a few days are most actionable for timing. Confidence falls with lead time, especially for local wind ramps and convective systems. Beyond that, use the ensemble spread and scenario planning.

What wind speed should I use as a threshold?

Use the operating limit from your equipment, permit or procedure. Common planning examples include 8, 10, 12 and 15 m/s, but there is no universal safe threshold across turbines, cranes and vessels.

Does the model provide direction or only speed?

Wind is normally represented as a vector, which means speed and direction can be derived from the field. Check the exact variable and access channel you use before building a workflow around it.

Is the forecast updated every hour?

The WeatherNext 3 operational model is designed for hourly initialization. The newest run may not be available instantly across every access channel, so record the initialization time with any operational decision.

WeatherNext 3 Wind Forecast: Speed, Direction and Timing

WeatherNext 3 produces hourly wind fields for global surface forecasts, including 100 m wind relevant to turbine-height planning. This guide explains what the wind forecast can answer, how to turn speed and direction into an operating window, and where a 10 km surface grid still needs local measurement. For the complete variable workflow, see the forecast guide; for the model behind the fields, see the model guide.

What the wind forecast actually provides

The useful forecast is a time sequence of speed and direction, not one daily wind number.

100 m

Turbine-height wind is included in the model's surface forecast variables.

Hourly

The sequence exposes when a wind ramp starts, peaks and fades.

10 km

Most non-station surface grids resolve around 0.1 degrees.

15 days

The horizon supports short operational windows and longer scenario planning.

How to read a WeatherNext 3 wind forecast

Read four qualities together: speed, direction, persistence and uncertainty. A single maximum wind speed hides the operating window.

Read the model guide

Speed

Compare wind speed against an operating limit such as 8, 12 or 15 m/s. A threshold converts a general forecast into a yes-or-no condition.

Direction

Direction changes exposure, fetch and wake behavior. Two hours with the same speed can have different operational consequences.

Persistence

Look for a usable block of hours rather than one isolated peak. Maintenance, lifting and vessel windows depend on sustained conditions.

Ensemble spread

The 64-member ensemble shows whether a windy scenario is robust or one member among many. Use the range when the cost of being wrong is high.

A practical operating workflow

Turn wind data into a decision window

Use the same sequence for wind energy, construction, marine work or event planning.

Fix the exact site

Use the coordinates or nearest location that matter. A regional wind forecast can hide ridge, coast and valley differences.

State the limit

Write down the operating threshold, including any gust or direction constraint. The limit should come from your own equipment or procedure.

Find the block

Scan the hourly curve for a sustained window on the safe side of the threshold. Note the margin around the start and end.

Recheck the next run

Each hourly run may move the ramp. Compare the new timing before committing people or equipment.

Where the wind forecast needs care

A global surface model is a planning layer. It is not a site-specific turbine control system.

Sub-grid terrain

A 10 km surface grid cannot represent every building, cliff, forest edge or turbine-site wake. Local terrain can shift wind materially.

Wind is not gust

Mean wind speed and a short-duration gust are different quantities. Use the model for planning and a certified measurement or warning system for safety.

Hub height matters

100 m wind is useful for turbine-height planning, but every asset has its own hub height and power curve. A model field is not a production guarantee.

Official warnings rule

For severe weather, marine warnings and evacuation decisions, follow the responsible meteorological service. WeatherNext 3 is not an alerting authority.
