Hmm. Mt. Wilson in southern California at 5700 feet averages a low 63.6°F (17.6°C) in July, 20°C has happened before (record min is 82°F, seems a bit hard to believe but there are lots of 79°F recorded). Pasadena at the foot of the mountain averages slightly cooler 15-16°C.
Thats in SoCal which is warm for the latitude. And on/near desert. Mt. wilson is only few hundred miles from Death Valley.
I was talking about island in deep tropics, in a mountain slightly higher than mt. washington.
Using -2c every 1000 feet means avg sea level low of 29c in July.
Using -2.5c every 1000 feet means sea level avg low of 31.85c in july.
Using -4f every 1000 feet means avg sea level low of 30.2c in July.

Note that in Southern California, the average summer low at sea level was colder than at 5700 feet.
Windy for the west coast S of Trondheim tomorrow afternoon and evening.
Extreme weather warning - "Nina". Up to hurricane sustained wind speed expected in the most exposed areas (Stad peninsula).
A burst of snow and cold winds is moving in, only to then melt a day later. Classic US East coast winter. This endless cycle of freezing and thawing is really starting to hit roads hard.
This winter seems to be sunnier than normal. December at Leeming had around 83 hours of sun. Probably similar here, if not more, since Leeming tends to be duller. It has 27 hours so far this month.
