What's in it

Data offered docs-verified: GRIB2 atmospheric model data (sub-setable by region, parameter, level, time step, model run) · global and UK deterministic NWP forecasts · global and UK ensemble forecasts · site-specific spot forecasts (hourly, 3-hourly, daily) · site-specific blended probabilistic forecasts · National Severe Weather Warning Service (NSWWS) warnings · UK land surface observations (hourly) · PNG map images (surface temperature, precipitation rate, total cloud cover, MSL pressure)
Coverage docs-verified: UK and global
Resolution docs-verified: 2 km (UK deterministic); 10 km (global deterministic); site-specific spot data is for a single point
Update frequency docs-verified: Warnings updated as they are issued, updated, cancelled or expire; forecast run cadence not stated in docs
Formats docs-verified: GRIB2 · GeoJSON · Atom Syndication (NSWWS warnings) · PNG · JSON
Access docs-verified: Registration and subscription via Weather DataHub; free tier or paid plans (per metadata); API calls metered by daily request limits; data plans metered in GB; licence: Met Office Weather DataHub Terms and Conditions

Useful for

Use cases llm-inferred: Site-specific rainfall and temperature forecast inputs for a drainage or flood risk assessment using spot data · Ensemble forecast spread to frame uncertainty in flood or surface water modelling · Recent hourly UK land observations to check or calibrate rainfall and temperature inputs · Severe weather warning monitoring for site-based construction or fieldwork risk assessments
Audience llm-inferred: flood consultants · drainage engineers · hydrologists · civils engineers · environmental consultants

Limitations

Constraints llm-inferred: Spot forecasts cover a single latitude/longitude location per call · Daily API request limits apply and reset at 00:00 UTC · Data plans are metered in GB, and order-size estimates are guides only · Subscription and payment required; Terms and Conditions apply · Warnings feed is event-based, not a continuous forecast series · Gridded models are 2 km (UK) and 10 km (global), so local detail is limited
