Caldey Island (Pembrokeshire) weather

Headline:

Heavy showers possible on Saturday, then much warmer on Sunday.

This Evening and Tonight:

A fine end to the day across most of Wales, but a few showers are possible, especially in coastal regions overnight. Clear spells for many though and turning rather cool in the countryside with patchy mist and fog possible. Minimum temperature 8 °C.

Saturday:

A band of rain moving into western coastal regions during the morning, this breaking up to scattered heavy and possibly thundery showers for the afternoon. Occasional warm sunny spells too. Maximum temperature 20 °C.

Outlook for Sunday to Tuesday:

A fine and settled spell of weather from Sunday and into next week with bright skies and some strong sunshine at times. Turning much warmer and winds staying light.

The end of July and into early August will typically be dominated by a northwest-southeast split. North-western areas will probably experience rather breezy conditions with cloud and some outbreaks of rain or drizzle as weakening Atlantic frontal systems attempt to push eastwards across the UK. Toward the south and east it will tend to be drier and brighter much of the time, although there is also the small possibility of some thundery showers spreading in from the nearby continent at times. Temperatures during this period will probably be close to or slightly above average overall, with the likelihood of some very warm conditions developing in the south and perhaps parts of the east at times.

No single weather type is expected to dominate through this period. Some spells of dry, settled weather will likely alternate with wetter, cloudier conditions at times. The wettest conditions will probably be in the northwest, with the southeast tending to be driest. Through the period as a whole, warmer than average conditions are more probable, perhaps with some short-lived hot spells.
