With a Cwa climate, characterized by a distinct dry season, Rio Pomba experiences varying UV levels throughout the day—from a moderate index of 3 in the morning to a peak of 8 around midday. Understanding these UV levels is crucial for everyone to enjoy the sunny Brazilian days safely while safeguarding against the risks associated with excessive sun exposure.
The UV Index throughout the day reveals a sharp increase in intensity, peaking around 12:00 PM, where it reaches an impressive 8.

Following this, May through August sees a slight decrease to the very high risk category; however, individuals should still take care, as burn times increase to about 15 minutes in May and July. In September through December, the UV Index returns to extreme levels in September and stays elevated through November, with the burn time once again dropping to 10 minutes.
