We here and Ventura Visitors and Convention Bureau share a lot of photos of brilliant vibrant sunsets and during fall the question is always asked..
Why do sunsets look different in winter?
Why are winter sunsets colorful?
Why are sunsets different in the winter time?
It comes down to visible light and angle of the light coming from the sun at this time of the year. Light not only interacts with particles in the air but is altered by it. The video below is an excellent run down of what wavelengths are visible and why.
Once you understand these wavelengths we can move on to the light coming from the sun at sunset and sunrise. This light is coming from much further away and has much more particles to pass through . Red and orange have much longer wavelengths compared to blue, making it easier for this light to travel that long distance without being scattered. This is then amplified by how slow the air is moving during winter than it is in the summer. According to the NOAA “air circulation is more sluggish during the summer, and because the photochemical reactions which result in the formation of smog and haze proceed most rapidly at that time of the year, late fall and winter are the most favored times for sunrise and sunset viewing over most of the United States.”
Simply put, Ventura has incredibly colorful and vivid fall sunsets because of the distance light travels from the sun to our pristine coast. So next time you’re walking on the beach in that golden hour before the sun sets you’ll now know why those colors are so vibrant. If you happen to capture one of those magical shots be sure to tag #visitventura; we love to share them.
