Temperature glitch

[idefix37]

Meteogram shows weird temperature curve near Switzerland (in France 15km from Geneva).

Higher temperature at 04:00 than in the day.

I found the same anomaly in about 10 locations in this area that I checked via windy.com using meteoblue model.

Oui, anomalie récurrente, ici entre Le Chesnay et sa voisine Louveciennes

Hello,

We took a closer look at the anomaly you reported and found that there were indeed discrepancies in some of our weather data on the night in question.
This likely explains the reversed or shifted display of day and night temperatures that you described and also why you noticed this issue in several locations around Le Chesnay and Louveciennes.
With a genuine weather phenomenon like an inversion, such a consistent pattern across ten locations would be rather unusual, so we suspect this is more likely a bug.

We’re continuing to investigate internally to determine exactly what triggered this, so that something like this doesn’t happen again in the future.
However, the data should have returned to normal by now, so the displayed values should be accurate again.

If you notice the anomaly again in the coming days, please let us know via a support ticket ideally including the location and time so we can specifically check whether the pattern is recurring.
