Boston Seasons to Sun Angle

Boston Summer (Solstice)

A high Sky Angle results in each ray of light hitting a smaller area providing direct sunlight with the heat energy produced covering a smaller area.

Number of hours daylight starts at 24 hours at 70° N latitude to 12 hours at 0° latitude to 0 hours at 70°S latitude due to Northern Hemisphere tilted toward the Sun and the Southern Hemisphere tilted away (See image above).

Boston Fall (Equinox)

During and Equinox, all latitudes receive 12 hours of daylight and 12 hours of night. This is due to the Northern Hemisphere and Southern Hemisphere neither tilted toward or away from the Sun (See image above).

Boston Winter (Solstice)

A low Sky Angle results in each ray of light hitting a larger area providing indirect sunlight with heat energy produced covering a larger area.

Number of hours daylight starts at 0 hours at 70° N latitude to 12 hours at 0° latitude to 24 hours at 70°S latitude due to Northern Hemisphere tilted away from the Sun and the Southern Hemisphere tilted toward the Sun (See image above).

Boston Spring (Equinox)

During and Equinox, all latitudes receive 12 hours of daylight and 12 hours of night. This is due to the Northern Hemisphere and Southern Hemisphere neither tilted toward or away from the Sun (See image above).
