Only place in the northern hemisphere where temperature at sea level did not leave the 10°C to 30°C range in this millenium.
These values are deducted from values recorded by a station 25 meters above sea level right on the cliffs on the background: lowest of 8.8°C in the night of 23 February 2003 and highest of 30.5°C, although in average there were 15 days above 29° each year.

In the southern hemisphere two more places: shores of Norfolk Island and Lord Howe Island.

At this very point the quintessential meridian begins a journey over water that will end only in the Antarctic.
