Dropped to -6.1 in Penzance last night, which for this site is quite
exceptional. Easily the coldest I've recorded, and coldest in Penzance
since 1987.

Since I my records started (1991) the only nights to see the
temperature drop below -4C were 1st, 2nd, 3rd Jan 1997.

Now 2 frosts this winter, probably a 3rd tonight, and that will be it
for a while.
