Historic NOABL Wind Speed Lookup

This tool provides a quick early-stage wind resource screening using archived NOABL data. Results are indicative only and should not be treated as a substitute for site measurement or project-specific yield modelling.

Enter a grid reference or postcode to estimate wind speed.

Important Note

Use as an Early-Stage Screening Tool Only

A mapped result can help indicate whether a site may be worth further review, but it does not replace practical wind engineering judgement.

1km

Grid-Based Estimate

The result relates to the wider grid square and not a precise measured point at the turbine position.

Site

Terrain Still Matters

Hilltops, ridges, valleys, trees and buildings can all influence the actual wind seen by the turbine.

Yield

Simple Energy Indication

Any generation output shown should be treated as an early screening figure rather than a bankable yield prediction.

Understanding Wind Resource

Wind speed alone is not enough — siting and exposure play a critical role in whether a turbine performs as expected.

Wind Turbine Siting

Understand how terrain, exposure and surrounding obstacles influence turbine performance and long-term reliability.

Estimating Wind Speed

Build an early-stage understanding of wind resource using maps, datasets and practical site-based judgement.
