Throughout the year, the UV Index experiences significant fluctuations, with the highest values occurring from March to September, indicating critical periods for sun exposure. March marks the beginning of very high levels, escalating to extreme conditions in April and peaking in June at a UV Index of 15. The high-risk months for sunburn are therefore March through September, where the burn time narrows to just 10 minutes during the extreme exposure days. In contrast, the UV Index drops in the fall and winter months, with January and December having a moderate exposure level (UV Index of 4) and longer burn times of 30 minutes.
