Tomorrow’s Outlook
Tomorrow brings a similar temperature to today. Light rain is possible, though a 32% peak chance means much of the day could stay dry. That risk lines up with humidity averaging 80% through the day the more moisture in the air, the more readily clouds build into showers. Humidity stays high near 80%, so it will feel muggier and stickier than the temperature alone suggests. A light breeze near 16 km/h is expected. Sunrise is at 5:58 AM and sunset at 6:12 PM, for about 12h 14m of daylight.
