The water temp. on big lakes seems to be much less
compared to readings from satellite measurments.

For example windy shows 8C at Prespa lake (Greek-Albanian border)
while NASA measures it 19C.
The same for Lake Balaton, Hungary, Lake Geneva etc.

like the one mentioned here (currents)

I don't know where is coming from the temp. provided in windy (8C)
