The dry season lasts from October to May, the hottest months appear to be in March and April, when the heat is increased by the burning of the corn and henequen fields.
August is the most rainy and May the hottest month.
July is the hottest and January the coldest month in the year.
The hot season of the year is from May to October, July and August being the hottest months.
Nearly all the moisture that is precipitated during six or seven months is stored up in the form of snow, and is gradually diffused in the course of the succeeding summer; even in the hottest and driest seasons the reserves accumulated during a long preceding period of years in the form of glaciers are available to maintain the regular flow of the greater streams. Nor is this all; the lakes that fill several of the main valleys on the southern side of the Alps are somewhat above the level of the plains of Lombardy and Venetia, and afford an inexhaustible supply of water, which, from a remote period, has been used for that system of irrigation to which they owe their proverbial fertility.
