Temperatures in May
In May, the mean high is 20.6 °C and the mean low 15.7 °C, a gap of 4.9 °C between afternoon and night. That is almost exactly the year’s average high (20.6 °C). Nights run 0.6 °C warmer than the year’s average low (15.1 °C). The afternoons are warming: 19.5 °C in April, 21.4 °C in June. A light jumper is enough in the evening, more so near the water.
Wind in May
The wind passes 15 knots on about 15 days out of 31, against 12 days in an average month. April has 15 days, June 16. It blows mostly from the north, and its daily peak averages 15 knots. These figures are our own count over thirty years of modelled weather data (the ERA5 reanalysis, then the ECMWF’s IFS model from 2017), 1991 to 2020. Over 2011–2020, the Essaouira station’s hourly reports count 18 days at 15 knots or more in the month. The two sources differ here by more than 2 days. We count May in the kitesurf and windsurf season.
