Résumé : Mainly due to a lack of information on the local climate and its consequences on timber buildings, and regarding Eurocode standard, French West Indies islands and French Guiana remain considered as a service class 3 (SC3). Based on Meteo France (MF) data and moisture content measurements on more than 300 sites in the three departments, on local surrounding air humidity and temperature, the three programs Bois Duramhen 971 (European Synergîle), 972 and 973 (PACTE) are devoted to give answers on the impact of this climate on soft and tropical woods integrated in traditional or new timber structures. Data acquisition and analysis are described. Measurements are performed during more than one year, they are compared and completed by Meteo France data. The analysis is divided in two phases: equilibrium moisture content (EMC) calculated from HR(%) - T(°C) with NFEN1995-1.1/NA moisture diagram and direct measurement of instantaneous MC. Monitoring approaches are performed on, at least few members of two real buildings. In Guiana, drying element are also monitored in order to analyse this natural drying phase. Results obtained by the different approaches, comparison of measurements, calibration of measurement equipment, led to a wide data base and proposals of mapping have been deduced.
