Chilly Days and Nights and the Return of the Waxing Crescent Moon
Recent Chilly Days and Nights only confirm that San Diego's lowest temperatures (according to more than a century of weather records) tend to occur during the month of January. January's mean temperature at Lindbergh Field is about 55 degrees Fahrenheit. (July's mean is a balmy 70 degrees.) To experience much colder temperatures, journey to the Cuyamaca Mouintains; -1 and -4 degree readings were once recorded there — the two lowest temperatures ever recorded in the county.
The Waxing Crescent Moon returns to easy visibility in the evening sky on Thursday, January 6 — though sharp-eyed observers might spot it very low in the western sky at dusk on the previous evening. The moon's "thin-grin" form will tilt slightly to the left as it hovers above the last bit of evening twilight glow.
