Personnel director Helen Hyde said: "This was driven by warm weather and popular promotions with shoppers preparing for an alfresco style bank holiday weekend. The soaring temperatures boosted barbeque products which saw a 69 per cent uplift and salad sales increased by 24 per cent.
As customers kept cool, ice lollies saw an uplift of 108 per cent with hand held ice creams up 100 per cent. Rosé wine and gin were among the most popular tipples seeing sales rise by 65 and 36 per cent respectively.
Customers were clearly enjoying time in their gardens as outdoor plant sales blossomed by 11 per cent.
Meanwhile, fashion sales dropped 10 per cent at John Lewis as the warm weather hit home, and suitcase sales went up 37 per cent, suggesting more holidays being taken.
