It's too hot to shop! Temperatures in stores hit almost 30C - making it warmer than Sydney
Visitors to one shop at the Westfield centre in west London faced sweltering temperatures of 29.4C (85F) yesterday, our study found. In many other stores, including H&M, River Island and M&S, the heat reached more than 26C (79F). This means customers had to rifle through the racks in higher temperatures than those soaking up the sun in Sydney yesterday - where it was a balmy 25C (77F). Conditions were not much better elsewhere; shops at the Bluewater centre in Kent reached up to 27.4C (81F), while the Trafford Centre in Manchester and Newcastle's Eldon Square saw highs of 24C (75F).
