Porthleven - West (Beach) (Cornwall) weather

Headline:

Clear spells with patchy frost overnight. Fine, but breezy tomorrow.

This Evening and Tonight:

It looks dry this evening and overnight with clear periods. Patches of frost and fog forming in the east, though fog lifting onto the hills during the early hours as winds strengthen. Cloud also slowly increasing in the far west. Minimum temperature 2 °C.

Monday:

Early frost and fog in the east lifting to leave a largely dry day. Plenty of sunshine, though cloudier at times across Cornwall and parts of Devon. Brisk winds easing. Maximum temperature 8 °C.

Outlook for Tuesday to Thursday:

Mostly dry with some bright or sunny spells, and winds mainly gentle. Temperatures around average, though some frost and fog still possible where cloud breaks develop overnight.

High pressure will lie close to the southeast of the UK initially, with generally settled conditions across many parts. Cloud amounts will be variable, with some frost and fog in the south and east, this slow to clear, but some rain in the far northwest. A weakening frontal system looks like it will edge east across the UK over the weekend, before high pressure briefly builds back in from the west in its wake. Low pressure then seems likely to increasingly influence the UK weather later in the period, with some rain and windier conditions affecting most if not all parts. Temperatures are likely to be generally a little above average, especially in the north, though more frost and fog patches are likely under clearer skies and lighter winds.

A dominant flow from the Atlantic looks likely to produce an unsettled, milder and windier than average period. This is likely to result in areas of rain and periods of stronger winds affecting most if not all parts of the UK at times, though with the wettest and windiest weather probably occurring towards the north and west. However, the potential for brief colder spells with associated frost, ice and snow remains, following any deep lows crossing the region.
