MADRID, Spain — Inditex, the world's biggest clothes retailer and owner of Zara stores, reported a slowdown in sales growth in its third quarter on Wednesday as Europe's warm autumn kept shoppers away, although analysts pointed to a brighter end of the year.

Fashion retailers such as Next and John Lewis have already reported a hit from warmer-than-usual weather as shoppers passed on new winter ranges. Inditex's biggest rival, Sweden's H&M, will report results on Friday.

Inditex's sales between August and October rose 6 percent to €6.3 billion ($7.4 billion), in line with analysts' forecasts, against 10 percent growth in February to October. Third-quarter net profit rose 2.7 percent to €975 million.

"The top line is showing a big deceleration versus previous quarters," analysts from Kepler Cheuvreux wrote in a note.

They said most of the lower growth was already priced into the shares. Inditex shares have fallen about 5 percent so far this year, while H&M's have fallen almost 20 percent.

The arrival of chilly weather in November should boost Inditex's sales again, analysts said, and its shares opened up 4 percent.

Inditex said sales at its more than 7,500 stores and online increased 13 percent at constant exchange rates between November 1 and December 11, as shoppers snapped up items such as oversized sweaters and puffer parkas from new collections.

Analysts said the lower sales growth and a strong euro helped push Inditex's gross sales margin for the third quarter to 58.4 percent, down 33 basis points from the year before.

Inditex's profits are sensitive to fluctuations in the euro as it makes most of its clothes in the euro zone to respond quickly to fashion trends but generates more than half of its sales in countries outside the currency bloc.

The Spanish retailer's other brands include teen label Bershka and underwear chain Oysho.
