The wet summer has done little to stop the tills ringing at the stores and Waitrose food shops the company runs.
Overall sales increased 9.5% to £181.37 million with John Lewis rising 15.3% to £71.56m and Waitrose up 6.1% to £109.81m.
All three Scottish John Lewis stores posted growth and were singled out as among the best performing across the entire estate.
Glasgow increased 14.5% to push it 0.6 ahead for the year so far with Aberdeen 11% up on the week and 1.7% on the year and Edinburgh's 8.9% weekly rise leaving it just 0.2% down for 2012.
Sales from the online operation were around 45% up on last year. A rush for Olympic-related goods helped the gift division to a 51% uplift while sportswear and equipment was also 17% higher.
Electricals and home technology was described as the star performers by the company with sales 34% up.
Paula Nickolds, buying director for home products at John Lewis, said: "The continued miserable weather, coupled with the third week of a successful clearance, saw customers heading to our shops for some retail therapy.
"The best results were delivered by the maturing at home branches – Poole, Swindon, Croydon and Tunbridge Wells – and congratulations also go to the Scottish branches which achieved some of the best results in our full-line estate.
"Unsurprisingly, the weather had a big influence on how customers were spending their money and, while most categories benefited from an increased footfall, outdoor living and some clothing departments found sales much tougher to come by.
"The summer months are likely to require a flexible and reactive approach to trading."
At Waitrose, Andy Murray's run to the Wimbledon final was credited as helping a 6.1% increase in strawberry sales with more than 11 million sold.
Cream grew by 6.8% while whisky showed a 12% rise.
Tom Athron, finance director at Waitrose, said: Shoppers continue to turn to food more commonly associated with our winter months – there was a 7.8% uplift in poultry sales and a strong performance from pre-packed beef and lamb
"Vegetable sales also saw a 19% increase on the same time last year with leeks and cabbage selling particularly well.
"Ready meals and canned soups also had a great week as people elected for a night in rather than endure the rain."
