Spokesperson for the weather agency Ana Casals said there is ‘no strong climatological signal’ to suggest heat waves or higher temperatures than in previous years.
Another AEMET spokeswoman, Delia Gutiérrez, added: “This summer the forecast is not showing a clear signal, unlike other years when there were signs of a very hot summer ahead.”
Only Catalunya, Valencia and the Balearics are expected to be warmer than usual in the coming months.
There is also, to date, no indication of any impending heatwave.
Last summer was one of the hottest on record, with five heatwaves and temperatures soaring above 40C.
Cordoba in Andalucia reached 46.9C on July 13.
Since 1975 there have only been 10 summers without heatwaves, most recently in 2014, 2010, 2002 and 2000.
The mild prediction comes after the wettest spring in Spain since 1965.
