The State Meteorological Agency (Aemet) has considered that, most probably, in the Pitiusas, in the next trimester higher than normal temperatures will be recorded and the amount of precipitation will be usual.
As highlighted by the Aemet in a statement, autumn will begin on Sunday, September 22 and will last until Saturday, December 21.
In this quarter it usually rains an average of 180 liters per square meter (l/m2) in Ibiza and 130 l/m2 in Formentera. The predictions indicate that the most likely is that it will rain around that amount, Aemet has pointed out.
