The medicane that affected the central Mediterranean caused a major change in the sea surface temperature. While the central Mediterranean was significantly warmer than average before the medicane, it is now significantly colder than average.
Strong upwelling of deeper, cooler water through wind and wave action of the medicane has mixed surface waters and cooled them. While the Mediterranean was significantly warmer than the long-term average before the medicane, it cooled strongly due to the medicane. Now the central Mediterranean is significantly cooler than average: 1 to 2.5 °C below average, a cooling of 3-4 °C. Also note the cooled central Aegean sea, along the track of the medicane.

Note also that the Adriatic sea has cooled considerably: the effect of upwelling and mixing caused by strong Bora winds.
