Researchers have worked out how the cost of various holiday destinations increases as the weather gets hotter during peak season, in an effort to help families reduce their expenses. A week-long trip for two adults and two teenagers from London to Benidorm, Spain, in May when the temperature is 22 degrees, will cost a family £803. However, this price jumps to £1,570 in August when the temperature reaches 30 degrees - that's an extra £96 per degree.
Families who choose to travel outside of the peak weather period could save an average of £235 per degree lower in temperature across seven popular destinations. This saving could be used towards other parts of the holiday, such as children's activities, dining out or shopping. A week-long holiday for a family of four in Florida comes to £2,100 in May when the typical temperature is 29 degrees.
But this nearly doubles to £4,043 in August, when the average temperature is just two degrees higher at 31 - an additional £972 per degree. The research was commissioned by the Post Office, which also discovered that trips to Cyprus cost a family of four £737, for a milder 24 degrees in May. But this increases to £1,272, or £89 per degree, for a week in 30-degree heat in July.
Greece is one of the more affordable options, with a family paying around £1,793 for 28 degrees in August, but it costs just £1,285 in May at 23 degrees. A study of 2,000 travellers revealed that four in 10 holidaymakers planning a trip this year are opting.
