High pressure should prevail for most of the outlook period, maintaining largely settled conditions for much of the time. This should result in lengthy spells of dry and bright weather. It will be breezy at times, especially in the southwest at first. Daytime temperatures will depend on the wind direction and cloud amounts, but most places will be warm for most of the period, and very warm days most likely will be further inland. Overnight frosts are possible on clear nights where winds fall light. There is also the chance of some areas of low cloud or fog, notably around the east coast. Towards the middle of April, the weather may turn more unsettled as rain or showers try to push in from the west.

An unsettled period is likely around mid April, with interludes of rain or showers at times. Despite being unsettled, there will be fair conditions between weather systems. A return to high pressure is favoured later in the month, bringing mainly dry and fine weather. Temperatures are likely to be around average at first, before climbing to above average later in the more settled weather. This means some warm or very warm days, especially further inland where winds stay light on fair days. This could also mean there might still be some chilly nights any clear skies.
