Climate data for Saint-Philippe (1981−2010 normals, extremes 1989−present)
A notable event in the commune's history was in 1897, when the British troopship RIMS Warren Hastings ran aground in the middle of the night. Two seamen died as a result, the crash sparked by a compass malfunction resulting from the eruption of the Piton de la Fournaise. On board the ship was some electricity, for which the village of Tremblet would have to wait until 1984 to finally receive.
