Low UV levels are observed in January and February (Index 1-2), allowing for longer outdoor exposure without major concern for skin damage (burn time of 45 minutes). As spring approaches, the UV Index rises to moderate levels in March and April (Index 4-5), reducing burn time to 30 minutes. The high-risk months kick in with May through August (Index 6-7), where protective measures become crucial as burn times decrease to just 25 minutes.
