Note 2 — Relation of the Western Islands Called Filipinas

The brisa is the north, northeast, or east wind, the vendavál the south or southwest wind. The observations made for a considerable period at the Jesuit observatory in Manila indicate the main prevalence of winds as follows: north and northeast, November to January, inclusive; east, February to April; south and southwest, May to October. See Algué's account of these winds, in his Archipiélago Filipino, vol. ii, ch. iv; also (with additional observations, and citations from other authorities) in Report of the Philippine Commission, 1900, vol. iv, pp. 227–256. In these is discussed the question whether these prevalent winds can be properly termed monsoons.
