Airports/California/Catalina Airport
Now. Catalina Airport is 85° and clear at 10 PM. The dew point is 39°, so the air feels dry and comfortable. Gentle breeze from the east-northeast at 9 mph.
Today and tonight. Tonight falls to about 79° by 7 AM, under a mostly clear sky. No rain is expected for the rest of the day.
The week. The warmest day ahead is tomorrow, near 95°, and the coolest Tuesday, near 65°. Rain is likely Tuesday (53%) and Wednesday (62%). Tomorrow is hot, 95°: heat is a danger to anyone outdoors for long.
The sky now. The Moon is a waxing crescent, 26% lit, and stays below the horizon until dawn. The next full Moon is Sunday, Oct 25. Look for Saturn, bright in the southeast. A planet shines with a steady light where the stars around it twinkle. The Orionids meteor shower is active, peaking around Oct 21: at its peak, up to about 20 meteors an hour can be seen from a dark site. The sky is forecast to stay clear: a good night to look up. The day is 11 hours 23 minutes long, 2 minutes shorter than yesterday.
As of 10:00 PM in Catalina Airport, California.
