About Peakify

Peakify is built and run by me, Sam Tyler. I'm a hillwalker, mostly in Eryri and the Lake District, and I've logged every summit in the Peakify app since June 2020.

How the site is made

The mountain forecasts are worked out automatically from computer weather models for each summit's real height. No forecaster writes them. How our forecast works lists the sources, the limits behind each Good, Marginal or Poor verdict, and what a model can't see.

Route lines are plotted on the map and checked against the paths, and you can download them as GPX. Peakify forecasts the weather; it can't tell you about ice on a shaded path or a closed track. Before a big day, also read MWIS or the Met Office mountain forecast.

Spotted a wrong height, a bad route or a forecast that didn't match the hill? I'd like to hear about it.
