On Thursday, the Portuguese Navy revealed in a statement that the Faro Buoy, which is part of the Hydrographic Institute’s national coastal monitoring network (MONIZEE), had recorded a daily average sea surface temperature of around 25°C.
The first marine heatwave was classified as moderate, with a daily maximum of 23.3°C, about 1.5°C above the 90th percentile threshold for that day. The second reached the strong category, with a maximum of 24.8°C, about 2.2°C above the 90th percentile.
In addition to the daily averages that underpin the detection of marine heatwaves, the records indicate that, during the period under analysis, the sea surface temperature reached a maximum of 26.1°C.
