• Wales & West: Likely to see more cloud cover and earlier onset of drizzle/rain toward the end of the week. Mids to late week still mostly dry.

• Southeast England: Best bet for keeping dry and sunnier spells. Slightly colder mornings, warming during daytime.

• Northern Ireland: Like western UK, cloud and occasional rain possible especially later in week.

What to expect overall

• Mornings and early evenings will feel quite crisp / chilly, especially inland. Layers will help.

• Daytimes generally mild, with temperatures in mid-teens turning toward 19-20 °C in the warmer spells.

• Dry conditions dominate early to mid-week; more risk of cloud and showers towards the weekend.

• Sunshine best through Monday-Thursday; after that clouds encroaching, and showers more likely.
