Why does the MetO, as it has for some time, show no observations for Scilly, whilst other sites quite happily show it.

The observations seem quite reasonable to me, they've certainly been more questionable at times.

Fantastic weather for a swim today at 14:00. Around 22C, high humidity, the earlier F2-3 ESE wind died and became a very gentle (F1-2) WNW, as it often does during the afternoon in these type of conditions. A very local effect associated with the later warming of the north coast (at least that's my theory). A pool of warm water off the Battery Rocks recorded as 21C!! The highest this year. Quite a swell though, a bit of timing required going up and down the steps into the sea.

SST 17C out at the Penzance buoy, so a rather fortuitous warm pool where the sun warmed surface water had piles up between the prom & the Jubilee pool.

Because there's no SYNOP only a METAR. And if I remember correctly,
METARs are only supposed to be used for aviation purposes. If this is
the case (has this changed Freddie?) then the MetO can't be seen to be
breaking the rules, whereas XC Weather et al are less constrained.
