Mid-May to mid-June, or September. Mid-May to mid-June offers long days, blooming gardens, and mild temperatures (avg highs ~68–74°F / 20–23°C) without the peak-summer crowds and heat. September is the best shoulder-season alternative: crowds thin, golden light, and temperatures remain comfortable before autumn rains arrive
