they are called, blow from the southeast to the north, finally blowing directly from the north; while in the other, or wet season, the vendavales blow from northwest to south-southeast. Thus, during these two seasons, the winds blow from every point of the compass. For this reason it will be seen that coming from Nueva España, from the east toward this western region, the brisas would help; while the vendavales, especially the usual one, which is a south-westerly wind in the channels of these islands, would impede the progress of the ship. These two general seasons begin in some years somewhat earlier than in others, and in some places before they do in others. However, it is quite clear and evident that by the end of May and the middle of June, the vendaval begins here from the west (and I believe that this is true of all the southern sea), and blows strongly night and day. Now if for any reason it should cease for a moment it would only be to burst forth again with renewed vigor. Such a period of quietness is called here calladas ["silence"]. The brisa begins in November, and lasts until the end of May. Between these two general seasons two others exist, called bonanças ["gentle winds"] which last from the middle of March to the end of May, and comprise also part of September and October. During that time the bonança of April and May is the most prevalent wind, although other winds are blowing constantly. Should the usually mild winds prove severe, then the opposite season would develop, so that in April a vendaval often presents itself, and in September a violent brisa may blow. These seasons, I think, correspond to those of the northern sea, as you may be already aware—although I do not know whether
