I am sure that others who have been in hot countries with mountains will know this. The night wind.
On still nights after a hot day things tend to cool off fast. But in my experience in a very strange, though obvious, way.
A river of cold air, less than a meter thick, flows down over the landscape like a broad river flowing onwards. This air can be very cold. The air above can still be quite pleasant even. But the feet! No more sandals. Boots at night.
And that reference thermometer sitting at 2 meters close by?
Well I’m not sure what it sees.
