Throughout the year, the UV Index fluctuates, reaching its peak during the summer months. January begins with a high risk (UV Index 6), while February escalates to very high (UV Index 8). The high-risk months of March through August highlight the need for caution, particularly from May to August, where the UV Index reaches an extreme level of 12. In these months, the recommended burn time reduces to just 10 minutes; therefore, protection against UV exposure is crucial. As summer fades, September and October still bear a very high UV risk, advising continued vigilance. As temperatures drop, November and December present lower risks with UV Index values of 6 and 5 respectively. Residents and visitors are urged to remain mindful of these UV changes and take appropriate precautions, especially during the sun’s peak hours.
