LABOR DAY WEEKEND Weather and Climate

The calendar says the first full day of fall will be September 23 this year, but many people consider Labor Day weekend to be the unofficial end of summer. From a climate perspective, which day is more representative of the change of seasons? The answer is Labor Day.

The sun is strongest at the summer solstice in late June. Since there is a time lag between the strength of the sun and the seasonal temperature curve, the warmest days of the year occur weeks after the summer solstice. The warmest months of the year are June, July, and August. The period from June 1 to August 31 is defined as meteorological summer in the northern Hemisphere.
