In Central Paraguay, sunshine duration presents a clear seasonal trend, with a marked increase in hours from the cooler months of winter to the warmer summer months. January and February bask in relatively high sunlight, with 274 and 306 hours of sunshine, respectively. However, it is March that shines the brightest, reaching 307 hours, which is indicative of the onset of warmer temperatures and longer days. The transitional months of April and May see a slight decline in sunshine hours but still boast strong totals, with 280 and 249 hours, respectively, as the region begins to prepare for the cooler winter.
As winter sets in, sunshine hours dip, with June recording the lowest at 228 hours. However, the trend begins to reverse in July, demonstrating a gradual increase as the days start to lengthen again, with 259 hours of sunlight. By November, sunshine hours peak at an impressive 317 hours, and December reaches the highest total of 366 hours, making it a prime time for outdoor activities and agriculture. This consistent increase in sunlight from winter to summer not only enhances the region's environmental vitality but also highlights the importance of solar energy potential in Central Paraguay.
The UV Index in Central Paraguay demonstrates significant fluctuations throughout the year, with the highest levels occurring during the summer months. January and February exhibit extreme UV conditions, with indexes of 15 and 14, respectively, leading to a critical burn time of just 10 minutes for unprotected skin. This pattern persists into March, which has a UV Index of 13, further emphasizing the need for precautions against sun exposure. As April arrives, the UV Index drops to 10, categorizing it as very high, but still necessitates vigilance for sun safety.
As the year progresses into the cooler months, the UV Index declines significantly, reaching 7 in May and 5 in June, categorized as high and moderate, respectively. July experiences a slight uptick to 6, accompanied by high exposure risks, before seeing another rise during late winter and early spring. Notably, August and September return to very high levels with UV indexes of 8 and 10. The cycle concludes in December, where the UV Index again peaks at 15, reflecting the strong solar intensity typical for Central Paraguay, underscoring the importance of consistent sun protection year-round.
