Rain begins to fall about eleven o’clock, and continues to augment rapidly from hour to hour until it reaches its maximum between four and five o’clock p. m.; from this time on it diminishes gradually until morning. The daily maximum of rain is reached about sunset, although in January the heaviest rainfalls are observed between one and two o’clock p. m. The most probable hour of rain is between four and five o’clock p. m. It seldom rains between three and four o’clock, and very seldom during the morning hours. Thunderstorms reach their maximum in May. The relative humidity of the air is such that the climate can be considered a favored one. Its annual curve shows three minima and three maxima. The minima are observed between February and March, in July, and between November and December; the maxima in June, September and December. These lines, of course, are parallel with those indicating the distribution of rain. The maximum is noted at sunrise, the minimum at two o’clock p. m., with an average oscillation of twenty-four per cent.
