Harter Fell 14-day summit weather forecast

How the Harter Fell summit forecast is made

The numbers come from the Open-Meteo weather model for the summit's position at 779 m, in the mountain's local time. A valley forecast would understate the summit badly, so the wind is worked out at summit height from the model's upper-air winds: the standard 10 m wind sits over the model's smoothed ground and is roughly half what an exposed top gets.

Peakify rates each day Good, Marginal or Poor from the forecast summit wind, gusts, chance of rain and wind chill. Wind of 40 mph or gusts of 65 mph make it Poor; wind of 25 mph, gusts of 45 mph, a 60% chance of rain or a feels-like temperature of -8°C or below make it Marginal. The verdict is the same one shown on the main peak page and in the Peakify app.

"Feels like" is the coldest apparent temperature of the day, which combines air temperature, wind and humidity. On a windy summit it can be well below the air temperature, so pack for that figure, not the high.

For a second opinion before a big day, read the Met Office mountain forecast or MWIS for the area. They are written by forecasters and cover hazards such as cloud on the tops and visibility that a model table can't.
