Two Indian air force helicopters were searching the mountains, but officials said the operation had to be suspended due to unfavourable conditions.
The missing group, including four Britons, two Americans, an Australian and an Indian, began climbing Nanda Devi on 13 May.
The British group leader's family said they were "deeply saddened".
Earlier, officials said four other British climbers had been rescued. They have been named by India TV as Mark Thomas, Ian Wade, Kate Armstrong and Zachary Quain.
