The coldest March was that of 1885, with a mean temperature of 18°, this following one of the coldest winters on record.

April is a month of much bright sunshine, which averages 193 hours, and the rainfall is less than in any other month of the year. Owing, however, to the position of Toronto upon the shores of Lake Ontario, winds off the lake, which in winter some-what temper the climate, now retard the upward trend of temperature, and vegetation makes rather slow progress. Up to the 20th light falls of snow may also occur, but this snow is quickly melted. After the 20th there is usually a marked improvement in the weather conditions, vegetation then making more rapid strides, and the swallows and insects become numerous. The date of seeding varies with the drying of the ground and will often be quite early in the month, but it is seldom general until the 20th. At this date, also, violets and a few other wild flowers are found in the woods, and elm and poplar are usually in bloom.

The three warmest Aprils were those of 1844, 1878, and 1895—that of 1878 was exceptionally warm, with a mean temperature of 49°.2, but 3°.2 lower than the temperature of a normal May. Occasionally very high thermometer readings are recorded towards the end of this month, the highest record being 89°.9 on the 22nd, 1842.
