Which model should I use?

The hourly forecast can be generated from either the Meteo France Arpege model or the UK Met Office UKV model, chosen using the buttons at the top of the page. UKV is currently available for UK locations only.

There is no single right answer. Which performs better varies with location and with the current weather pattern, so it is worth comparing the two when the forecast matters.

Two daily updates from each model are used.

About this forecast

Hourly steps

Toggle between hourly and three hourly forecast steps.

Range

Analyses a wider area to predict potential temperature extremes, peak rainfall intensity and maximum wind gusts.

Rain chance

The rain chance percentage comes from the precipitation forecast across a dynamically sized grid around your location. A value of 50% means there is a 50% chance of rain falling somewhere within that grid, not that it will rain for half the period.
