These come from the ERA5 reanalysis on a roughly 9 km grid, so they describe the area rather than your plot. A shaded, sheltered corner holds leaf wetness longer than open ground, so conditions there can favour it more often than the figure suggests. This is a climate profile, not a forecast — the panel above carries the current risk.
How to read the result
The result uses the location coordinates and the data available when calculated. Treat it as a signal to check conditions on site: a garden microclimate can differ from the weather-model grid cell.
