The sun is strong around midday: UV index 6, high. Unprotected skin can burn in under half an hour. Air quality is moderate (index 60): fine for most people, though people unusually sensitive to air pollution may feel it outdoors.
The week. The warmest day ahead is tomorrow, near 87°, and the coolest Tuesday, near 67°. The days ahead look dry.
The sky tonight. The sun sets at 6:26 PM. The Moon is a waxing crescent, 34% lit, and sets at 10:31 PM. The next full Moon is Sunday, Oct 25.

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.
