Sunshine totals ranged from 261.3hr at Fair Isle and 253.4hr
at Lerwick (Shetland) - both CS recorders - to 127.5hr at
Wattisham (Suffolk) - a KZ sensor. Percentages ranged from
165 at Lerwick (Shetland) - on the CS recorder - to 64 at
Herstmonceux (Sussex) - a KZ sensor and probably over-sheltered
as well.

Though the far north has the theoretical advantage of extra hours when
the sun is above the horizon, I would imagine that it must be
exceedingly rare for the highest monthly totals to be recorded there.
