The deal is the latest in a string of contracts signed by the online travel agency with third parties, including Eurostar, Ryanair, Formula 1 and Greenbee, the travel portal from the John Lewis Partnership.
The latest will see Expedia Private Label team up with the climate information website in a similar deal to host search and booking facilities for travel products, including car hire.
Weather2Travel director Jonathan Nigel said: “We are excited that weather2travel.com customers are now able to make informed decisions about likely weather and match these to some excellent hotel and travel deals made available through Expedia Private Label.”
Karen Vaites Bohannon, managing director for Expedia Private Label, added: “The site lends itself perfectly to the unrivalled travel services that Expedia Private Label offers.
“The breadth of the products provided by Expedia around the world means that customers have the widest range of travel options available to them at great prices.”
