The first “supermoon” of 2025 should be visible over most of the San Diego area on Monday night.
The National Weather Service office in San Diego predicts partly cloudy conditions along the coast, but clear skies inland.
According to NASA, a supermoon occurs when the Moon is full at its closest approach to Earth. During every 27-day elliptical orbit around Earth, the Moon’s distance varies from 226,000 miles to 251,000 miles.
The Moon will rise at 6:10 p.m. on Monday night and appear brightest at 8:48 p.m.
While the Moon will appear 14% larger than normal — about the difference between a nickel and a quarter — don’t expect a dramatic change in appearance.
“You probably won’t notice a big difference in size,” NASA says, but “it will appear a bit brighter than usual.”
Supermoons happen three to four times a year, and always appear consecutively. The next two are in November and December.
