Our Methodology
Unlike weather apps that predict cloud cover, our data measures geometric sun exposure — the maximum possible sunlight each pub's outdoor area can receive on a clear day. We use 3D raytracing to simulate the sun's path across the sky.
For each pub, we simulate 168 five-minute time slots (9am to 11pm) across all 366 days of the year.
Our data shows the theoretical maximum sun each pub can get based on its geometry and surroundings — not actual weather conditions. We measure sunshine minutes: the number of minutes per day where at least 50% of the outdoor area receives direct sunlight, assuming clear skies.
