A difference is not an error — the two sites are kilometres apart, at different heights, over different ground. What this is for is the pattern over time: a steady warm offset on calm sunny days points at the radiation shield, a constant pressure offset points at the altitude setting, and agreement across a week is real reassurance.

Forecast scoreboard
mean absolute error, °CEvery forecast is saved the moment it arrives, then compared against what this station actually measured when that hour came around. The figure is mean absolute error in °C — lower is better: how far out the forecast was, on average.
Columns are how far ahead the forecast was made. That split is the whole point — everyone is accurate three hours out, and the differences only appear at a day or more. Persistence is the baseline: simply "the same as it was 24 hours ago". A provider that cannot beat it is not adding anything, which is a more useful question than which one feels right.
| Collecting. Nothing here is meaningful until a few days of forecasts have been made and then lived through. |
