This weekend will see another short heatwave and as Kenny pointed out in the comments comes with a warning from the Scottish Fire and Rescue Service:

The Scottish Fire and Rescue Service (SFRS) has urged people who live within or who may enter rural environments to exercise caution.

The extreme danger assessment – released in conjunction with the Scottish Wildfire Forum (SWF) – will be in place from Friday, 11 July until Monday, 14 July. This covers central and eastern areas on Friday, 11 July, and extends to all areas, except low-lying areas with green grass, from Saturday, 12 July, until Monday, 14 July.

While this heatwave might be relatively short-lived, please be mindful of the impact of increased water temperatures have on fish. Already Loch Leven has suspended pike fishing on the loch due to the increase in water temperatures (Pike being particularly vulnerable to exhaustion and extreme stress in warm water temperatures).
