The temperature increase is 1.2 °C in 37 years at Anse Vata or 0.3 °C per 10 years vs. 1.0 °C per 10 years at the coastal station. Such observations are in agreement with the air temperature increase which started after the 1965–1969 cool period (Caudmont and Maitrepierre, 2007). A conflicting observation was made from the Amédée lighthouse time series, with a decreasing trend from 1966 to 1987 and a very low increase afterwards (Fig. 13)
