The start of this period will see a transition to a generally more settled weather pattern for much of the UK, as high pressure exerts more an influence. This will be most noticeable across southern and eastern parts, whereas areas further northwest could often be cloudier with some rain at times. With the build of pressure will come an increase in temperatures, with the potential for very warm or hot conditions to become established by mid-month, especially across parts of England and Wales. High pressure is favoured to remain close by to the UK towards the end of this period, bringing widely settled conditions and often above average temperatures.

High pressure is likely to be close by to the UK at the start of this period, although its position relatively to the UK is more uncertain. Whilst settled conditions look most likely, with a lot of dry weather in the offing, temperatures are more uncertain, though the potential does exist for further hot spells, especially in the south. Into July, it is possible that pressure may lower from the south increasing the chance of thunderstorms here.
