Porthleven - West (Beach) (Cornwall) weather

Headline:

A drier day albeit still the chance of a few isolated showers. Sunny spells are likely through the morning, but any sunshine turning hazy through the afternoon. Still breezy, though winds easing through the morning. Maximum temperature 17 °C.

Tonight:

Cloudy with showery rain affecting parts of Cornwall and west Devon through the evening, before a band of heavier and more persistent spreads eastwards overnight. Increasingly windy by dawn. Minimum temperature 12 °C.

Wednesday:

Heavy, persistent rain clearing eastwards through the morning, though remaining mostly cloudy with outbreaks of patchy rain and drizzle throughout the day, perhaps turning heavy at times. Breezy. Maximum temperature 19 °C.

Outlook for Thursday to Saturday:

Remaining changeable with showers or longer spells of rain at times, though brighter interludes are possible. Often breezy. A little milder and more humid by the end of the week.

The broadly unsettled conditions look to continue during the first part of this period. All areas are likely to see some further spells of wet and at times windy weather, interspersed with brighter, showery interludes. By the start of the following week, a ridge of high pressure may extend eastwards towards the UK, bringing an increasing chance of longer periods of drier weather to northern areas initially, whilst low pressure remains closer to the south or southeast. Towards the end of this period, high pressure may be rather more dominant across the UK. A cooler interlude is likely for a time through next week, with chilly nights and fog patches likely under the influence of high pressure. Temperatures probably return closer to average by late September.

Signals for prevailing weather patterns become fairly limited by the turn of the month and the early part of October. As is typical at this time of year, there are likely to be some spells of wet and windy weather along with some drier interludes but no strong preference to whether settled or unsettled regimes will be most dominant. Overall, northwestern parts are more likely to be wettest and windiest. Temperatures likely fluctuating around average.
