Recommendation
Morning window: 9:00 AM – 11:00 AM is ideal — sunny skies, temperatures warming into the low 60s, low humidity, and minimal wind. Evening window: 5:00 PM – 8:00 PM is also safe with mild temps (66–69°F), light winds, and very low precipitation chance. Avoid driving after midnight if possible, as rain shower chances rise to 50% into the early hours of Sept 22, bringing wet road conditions.
