This trend escalates in February, reaching 13, and peaks in March and April at 15, underscoring a serious need for sun protection to avoid harmful UV radiation. Even in May and June, the index remains high at 14, reflecting a sustained risk during the late dry season and early rainy season, when outdoor activities become more frequent.
As the year progresses, the UV Index slightly decreases but remains in the extreme category until late in the year. October sees a small drop to 13. By November, the index reduces to 11, yet exposure remains a concern, especially with a consistent 10-minute burn time alert. In December, although the UV Index falls to 9, it still reflects very high levels of UV radiation, extending the precautionary measures needed for sun exposure. Collectively, these data emphasize the importance of effective sun safety practices year-round in Alta Verapaz, particularly during the peak months of sun exposure.
