Where the sun is right now
Drag to move the sun and moon through the day
Chula Vista is the marker on the globe — on the daylit half right now, close to the line where day meets night, riding the dotted circle its spot traces as the Earth turns. The moon is 50° from the sun in the sky now, and that angle is the phase: waning crescent. You are looking down on the Earth from far above its orbit, from the north — the side you are on — with sunlight arriving from the top left, so the half of the Earth facing that way is the half having its day. Sizes and distances are not to scale; the directions are.
That angle sets the tides, too. The moon does most of the pulling and the sun about half as much, so when the two line up — new moon and full moon — their pulls add and the tide runs to its biggest (spring tides); when they sit square on at the quarters the pulls fight and it runs to its smallest (neaps). The coast follows a day or two behind, and the shape of the shore matters as much as the sky does. Predicted tide times for San Diego, San Diego Bay, CA →

Twilight, golden hour & blue hour
The three twilights are just how far the sun is below the horizon: civil to −6° (bright enough to read outside), nautical to −12° (the horizon is still visible at sea), astronomical to −18° (true darkness for stargazing). Golden hour is the warm, low-angle light photographers love, when the sun sits between −4° and +6°; blue hour is the deep-blue band just beyond it, from −6° to −4°. A dash means the sun never gets that low here on this date.

What time is sunrise in Chula Vista, CA today?
The card above computes it live in your browser for today's date, using Chula Vista's coordinates — along with sunset, solar noon, first light and last light, all in Chula Vista's own time zone.
What are first light and last light?
Civil twilight — when the sun is less than 6° below the horizon. It's bright enough for most outdoor activities before sunrise and after sunset.
Why do the times change every day?
Earth's tilted axis means the sun's path moves through the seasons — days lengthen toward the summer solstice and shorten toward the winter solstice, so sunrise and sunset shift a little every day.
