What day is the first day of summer for 2015? Summer begins with the summer solstice on Sunday, June 21, 2015. The exact time of the summer solstice varies upon an individualâs geographical location, but in New York City it will be at 12:39 p.m. EDT. The summer solstice is also known as midsummer, the first day of summer, and the longest day of the year.
In the astronomical calendar, summer begins on the June equinox â the point at which the Northern Hemisphere is tilted closest to the sun and the days are at their longest during the year. The summer solstice falls on June 21 this year, but the date varies from year to year, falling as early as June 20 or as late as 22 June. Since summer (and other seasons) can begin and end on different days each year on the astronomical calendar, it can be hard to compare seasons from year to year in this way. To standardize the length and start of the seasons, in meteorology, the 12 months of the year have been split up into four, 3-month periods. Therefore, in the meteorological calendar, summer includes the months of June, July and August - always starting on 1 June and ending on 31 August.
