We Are Off To One Of The Slowest Rainy Season Starts In San Diego’s History. After above-average rainfall seasons in 2023 and 2024, we’ve recorded less than an inch headed into 2025 with no chance of rain for the upcoming two weeks. We typically average over two inches of rain from October to December, and our highest monthly rainfall totals usually occur in January and February (about 2 inches each on average, according to weather-service statistics.) The U.S. Drought Monitor already reinstated an “abnormally dry” designation for much of southern and central California, including San Diego, earlier this month. But not all hope is lost. If a rainy second-half of January and a storm-filled February bring us their combined four-inch average, we will be just three inches under our average year going into Spring. March and April typically bring us over two inches. There have been other rainy seasons that had a sluggish start but shaped up to be closer to the regional average of 8.13 inches by the end of the rainfall year in September.
The Earth Will Be At Its Closest Point To The Sun on the morning of January 4th. This point is called the perihelion, from the Greek roots peri, meaning “near,” and helios, meaning “sun.” Because the earth’s orbit around the sun isn’t circular but elliptical — a stretched circular path — there are closest and farthest points in its cycle. In early January, we are 3% closer to the sun (1.5 million miles) than we will be in July, when earth reaches its aphelion.
2025’s First Meteor Shower Will Be This Weekend. The Quadrantid is one of the year’s best meteor showers and averages 25 meteors per hour at its peak. It’s a short shower, lasting from midnight to dawn, and peak viewing will be the 3-hour window before dawn on Sunday in the Northeastern sky. Hopefully, we’ll have clear skies, as the waxing crescent moon will cooperating with us, providing dark skies for optimal viewing. Head for the hills and find a space without city lights, bring a cozy chair or blanket, and enjoy the show.
