Minimum of 14.7C last night, warmest of the year so far.
Already 19.3C at 09:00 BST.

So warm pools of surface water forming now, even well out to sea.

E.g.

Sevenstones yesterday:-

14:00 - 60.6
15:00 - 61.0
16:00 - 61.3
17:00 - 61.2
18:00 - 60.1
19:00 - 61.2

(Not centigrade obviously - I can't be bothered to convert it,
anything 60f is warm)

It's surprising how much it fluctuates. It fell from 60.4F at 2300z last
night to 57.2F at 0300z this morning. Back up to 58.5F at 0700z.
