Alert. A Beach Hazards Statement is in force for Marshall's Beach until 9 PM Sunday. Read the alert in full, and see what it means in the Field Book.
Now. Marshall's Beach is 70° and clear at 11 PM. The dew point is 44°, so the air feels dry and comfortable. Light air from the north-northwest at 1 mph.
Today and tonight. Tonight falls to about 65° 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 85°, and the coolest Monday, near 61°. Rain is possible Tuesday (37%).
The sky now. The Moon is a waxing crescent, 35% lit, and stays below the horizon until dawn. The next full Moon is Sunday, Oct 25. Look for Saturn, bright in the south-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 13 minutes long, 2 minutes shorter than yesterday.
