Only six Septembers in the last 50 years have experienced temperatures above 30C, with three of those occurring in the last decade (2020, 2016, 2013). That warmth is no longer confined to the south as it was earlier in the week, with Scotland having a chance of hitting 28C on Wednesday.

However, the conditions are expected to change for most over the next few days, as the southwest of the UK sees the first of a front moving in from the west.
