Hawaii has the highest UV-attributable melanoma rate in the United States. About 65 people per 100,000 get melanoma here, and nearly 97% of these cases link to UV exposure. This makes skin protection a serious concern for everyone living in Hawaii, especially on Oahu. At Hawaiian Islands Dermatology in Kailua, Oahu, Doug Williams, MPAS, PA-C, helps locals understand why melanoma rates are so high and how to protect their skin.
Why Hawaii's UV Is Different
Hawaii’s location near the equator means the sun’s rays hit the islands more directly than in most places in the U.S. The UV index often reaches 11 or higher all year long. This is very high compared to many mainland areas where UV levels drop in winter.
The sun’s rays also reflect off the white sand and ocean water. This reflection increases UV exposure even when you are not directly in the sun. On cloudy or gray days, UV levels still measure around 7 to 8. This means clouds do not block all UV rays.
Trade winds can trick people into thinking it is cooler and safer to stay outside without sun protection. The breeze cools the skin, but UV rays still cause damage. This combination of strong UV rays and environmental factors makes Hawaii’s sun very intense.
What That Does to Your Skin Over Time
UV radiation damages skin cells. Over time, this damage can cause different types of skin cancer:
Basal cell carcinoma: The most common skin cancer, usually slow growing and found on sun-exposed areas.
Squamous cell carcinoma: Can grow faster and spread if not treated.
Melanoma: The most dangerous type, it can spread quickly and be life-threatening.
In Hawaii, locals often get diagnosed with melanoma in their 30s and 40s. This is younger than the national average. Early sun damage adds up over years, so even younger adults need to be careful.
What an Annual Skin Check Catches
A yearly skin check takes about 15 to 20 minutes. During this exam, Doug Williams, MPAS, PA-C, looks for any new or changing spots on your skin. He checks areas that get sun exposure and places that are hard to see on your own.
Most insurance plans cover annual skin checks. This makes it easier to catch problems early before they become serious. Early detection improves treatment options and outcomes.
Hawaii-Specific Factors
Hawaii’s population is very diverse. Many people have multi-ethnic skin types. Melanoma in these groups often appears in less common places like the palms of the hands, soles of the feet, or under the nails. These areas are not always checked during routine exams, so it is important to mention any unusual spots to your provider.
Outdoor work and water activities are common here. Surfing and beach work expose shoulders, ears, and lips to strong sun. These areas often get missed when applying sunscreen.
Volcanic smog, or VOG, can irritate skin and make it more sensitive to sun damage. Some locals say, “I don’t burn anymore,” but this does not mean the skin is protected. Skin can still get damaged even without visible sunburn.
Ingredients and Habits Between Visits
Using the right sunscreen is key. Hawaii Act 104 requires sunscreens to contain zinc oxide or other reef-safe ingredients. Zinc oxide protects skin by blocking UV rays physically.
Other helpful habits include:
Applying vitamin C serum to support skin health.
Wearing a UPF-rated hat to protect your face and neck.
Scheduling an annual skin check to catch changes early.

May is Skin Cancer Awareness Month. In Hawaii, this means making a habit of checking your skin yearly and treating any issues early. The strong sun here makes skin cancer a real risk for everyone. Protecting your skin is a year-round job.
Protecting your skin from Hawaii’s strong UV rays is essential. The high melanoma rate here shows how important it is to take sun safety seriously.
