Climate zone 1 – high humidity summer, warm winter. Climate zone 2 – warm humid summer, mild winter. Climate zone 3 – hot dry summer, warm winter. Climate zone 4 – hot dry summer, cool winter. Zone 1 is the coldest; zone 11 is the warmest. The USDA Plant Hardiness Zone Map helps gardeners determine which plants are most likely to thrive at a location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones.Zone 3 is 10 degrees F colder than Zone 4, etc. In addition, each zone is split in half. For example, sites in Zone 4a reach an average low temperature of -30 to -25 F, while sites in Zone 4b reach an average winter low temperature of -25 to -20 F.
