Hawaii: Plant Hardiness Zones, Climate & Soil Conditions

Our experienced writers spend hours deep researching, considering both scientific and experimental info to bring the insights you can trust.  

The leading traditional crops, sugarcane and pineapple, are grown on large plantations.

Fruits and vegetables are grown for local consumption, while greenhouse and nursery products, papayas, macadamia nuts, and coffee are grown for export.

Hawaii Island is particularly known for its production of macadamia nuts, papaya, banana, guava, avocado, and other specialty tropical fruits.

US Plant Hardiness Zone for Hawaii

Firstly let us have a glimpse of the US Plant Hardiness Zone Map of the state.

Plant Hardiness Zone Map for Hawaii


Hawaii, the oceanic American state, is tropical but experiences four different climate zones: tropical, arid, temperate, and polar based on altitude and topography on the constituent islands. 

The state comes under the 9-13a zone. Summer average high temperatures peak at 84°F, as highs usually do not breach 90°F, while the lows seldom drop below 70°F.

Winter average high temperatures are usually at 79°F, and the lows seldom dip below 65°F at night.


The Hawaiian Islands mainly exhibit two seasons: dry from May to September, which is hot and receives a minor amount of rain, and wet from October to April, which is warm and aggregates the majority of the annual precipitation of 32 inches.

Snow falls at higher altitudes such as Mauna Kea and Mauna Loa during the winter.

Mount Waialeale on Kauai records an average annual rainfall of 460 inches per year, which is the second-highest average annual rainfall on Earth.
