Unseasonably hot weather has been blamed for a four per cent drop in third quarter sales from the year-ago period by Spanish fashion retailer Inditex.

According to a company statement, high temperatures in Europe over August and September had caused the year-on-year decrease in an otherwise good sales year.

Inditex clothing sales had grown by 20 per cent in the nine months from February to October, and the company said comparable sales had gradually increased as temperatures returned to normal over the past three months.

Inditex's banners include Zara, Pull & Bear, Massimo Dutti, Bershka, Stradivarius and Oysho, with stores located across Europe, North America, South America and Australia.
