It’s summer and that means high temperatures and high density altitudes. We’re forecast to get near 100F this week. However, in Southern California, we usually have options. Take as an example, a recent METAR at my home base of El Monte:
KEMT 061847Z 22004KT 10SM CLR 32/15 A2997
A little before noon local time and it’s already 90F. But look just 23nm southwest to Torrance:
KTOA 061847Z 29012KT 7SM FEW008 24/18 A2998
That’s nearly 15F cooler. Torrance has two parallel runways and is usually not too busy. TOA does not allow pattern work on Sundays though. Long Beach is a considerably more complicated airport, so not my first choice for those early in flight training, but still GA friendly; you should have an airport diagram before going there. Hawthorne has a single runway, but is also an option; just make sure you don’t end up north of HHR and into LAX’s airspace.
