July Heat and a Crescent Moon
The Heat of Summer will most likely reach its feverish peak in inland San Diego County during July. (Coastal San Diego is different: since its weather is greatly affected by the slowly warming mass of ocean water adjacent to it, coastal temperatures usually peak in August or September.) The weather station at Borrego Springs commonly measures midsummer highs in the 110s Fahrenheit (the record high is 120.3°, a reading set on June 27, 1990), but certain locales in the low-lying, barren basins of Anza-Borrego Desert State Park -- notably the Borrego and Carrizo badlands -- probably experience even higher temperatures. Overnight camping in the desert in summer is relatively carefree -- little or no shelter is needed and early-morning temperatures are delightfully tepid. Prospective explorers of the desert in summer should take along enormous quantities of water and inform a responsible person of their whereabouts.
The Thin Crescent Moon returns to the evening sky Tuesday, July 13, visible only during evening twilight before it sets in the west. Notice how the sharp-tipped cusps point away from the sun, whose glare will be evident on the northwest horizon until well after sunset. With every passing evening, the increasingly thicker crescent will be spotted in twilight higher than and farther to the left of its initial position on Tuesday.
Venus and the Waxing Crescent Moon are in conjunction on Wednesday, July 14, with Venus lying about eight degrees to the upper right of the moon. Both will remain visible in the western sky through the entire twilight period.
