UK supermarket operators Tesco and Wm Morrison are expected to report strong half-year results next week, boosted by the UK's hot summer weather.

"Life could not have been better for the industry," one analyst was quoted by Reuters as saying. "The weather was perfect. When it's hot, superstores get a bigger share of the market because people don't want to shop around, and the products they tend to sell are more profitable."

Most analysts have forecast that Tesco's pre-tax profits, stripping out items such as goodwill and exceptionals, will increase 16.5% to a range of £630-643m (around US$1bn).

Tesco's group turnover is expected to increase about 15% to around £14.6bn.

Analysts are also forecasting second-quarter like-for-like sales growth of 5.8-6.5% at Tesco's UK operations.

Morrisons meanwhile, is expected to report pre-tax profits of £125m to £130m, a rise of around 12% on the year-ago period.

Turnover is expected to rise 14% to a range of £2.40bn to £2.55bn, reported Reuters.
