Moonkissed ~ That week is a bit far ahead. To get an idea of what the weather websites think, the metoffice Outlook for that week:
UK Outlook for Wednesday 25 Jul 2018 to Wednesday 8 Aug 2018:
We are likely to see a continuation of the changeable conditions into the start of this period, with rain or showers in the north and west, which may extend southeastwards to all parts. Further spells of fine and settled weather will probably return later in the month and into early August. However, there is the chance of more changeable spells of weather arriving from the northwest at times, which may bring the risk of thunderstorms across some southern parts. Temperatures overall are likely to be above the average for many. Some further very warm or hot spells are possible, more especially in the south and southeast. Temperatures will return closer to average in any changeable or unsettled spells of weather, perhaps more generally in the northwest.
And netweather:
Monday 30th July – Tuesday 7th August
This period will probably be more changeable with westerly and north-westerly winds quite frequent, but I do not expect it to be a washout, with some ridges of high pressure moving across the country, especially affecting the south. As a result temperatures, rainfall and sunshine will be much closer to the long-term normal for much of the country although there is a significant chance of the south and especially south-west staying drier than average with cloudier and wetter than average weather affecting the north-east of Scotland in particular. Mean temperatures for the period will tend to be between 0 and 1C above the long-term average.
So I think 'changeable' probably sums that lot up!
