Based on modelling and probability data, Aemet suggests that temperatures will once again be slighter higher than average for the last quarter of the year across the whole of the peninsula and the Balearic Islands experiencing an average temperature rise of 0.6C.
After a summer that was recorded as the ninth hottest on record, it seems we are heading for an autumn with less rainfall than is typical this time of year, apart from the Canary Islands where an increase in rainfall is expected.
In some parts of Spain summer will be brought to an abrupt close this week with the arrival of storms, high winds and torrential rain especially along the northern coast and northeast of the country.

Other parts of Spain however, notably the southern half of the peninsula will be enjoyingwhat the Spanish call a “veranillo de San Miguel” – when the warmer weather continues beyond the feast day of Saint Michael on September 29th.
This year some predict that we won’t be needing to pull out the long trousers and jumpers (that’s long pants and sweaters for American readers) until at least the first week of October.
