Expect a high of 74°F (23°C) and a low of 67°F (20°C). The day will start cool, with temperatures around 71°F (22°C) during the early morning, climbing steadily to reach the daily maximum around afternoon. Notably, humidity levels will hover around 51-67%, making it quite comfortable. Winds will be gentle, coming from the WSW at about 6-10 mph (10-16 km/h), adding to the pleasant feel. With a UV Index of 6, make sure to apply sunscreen if you're outdoors during peak sunlight hours! Rain is highly unlikely, which means you'll have a dry day ahead.

The trend of warm weather continues with a maximum of 71°F (21°C).
