Plant Hardiness Zone: Zone 10

Average annual extreme minimum temperature 30°F to 40°F (-1.0°C to 4.4°C)

Essentially frost-free or with very rare, light frosts that are short-lived. This zone supports a wide variety of tropical and subtropical plants, including many citrus species, avocados, and tender palms. The challenge here is often managing summer heat and humidity, rather than winter cold.
