The figure was the average time taken from a poll of 1,714 adults by online travel agent www.sunshine.co.uk.
Pressures of work and stress of family life were the main reasons given for wanting another break so soon.
Of those needing to get away again, 11 per cent cited weather as the main reason.
Nearly three in four of those polled said a foreign holiday was essential or very important, while 9 per cent said they could take or leave a trip overseas, and 3 per cent said they did not need a break.
Sunshine.co.uk co-founder Chris Clarkson said: “There are many people who feel a constant need for a holiday, no matter if they’d just returned from a fortnight in the Caribbean or if they’d not had a trip abroad for ten years.”
