Sertaozinho, a municipality in the state of São Paulo, Brazil, has experienced significant fluctuations in solar radiation exposure over the past several decades. Records from local meteorological stations reveal a gradual increase in sunlight intensity during the 1970s and 1980s, likely attributed to factors such as deforestation and urbanization. However, this trend reversed in the 1990s, with a noticeable decrease in solar radiation due to increased cloud cover and aerosol concentrations in the atmosphere.

Contemporary Sunlight Conditions and Their Impact

In recent years, Sertaozinho has experienced relatively stable levels of sunlight exposure, with an annual average of approximately 2,500 hours of sunshine. However, the distribution of sunlight is not uniform throughout the year, with higher intensity during the summer months and reduced exposure during the winter. The intense solar radiation can pose potential health risks to residents, including sunburn, skin cancer, and eye damage. To mitigate these risks, it is recommended to limit outdoor activities during peak sun hours, use sunscreen, and wear protective clothing.

Seasonal Variations

The humidity in Sertaozinho follows a distinct seasonal pattern. During the wet summer months, high humidity levels contribute to uncomfortable weather, particularly during the late afternoon and evening. The moisture-laden air often leads to condensation and fog, reducing visibility and creating a damp environment. In contrast, during the dry winter months, humidity levels decrease, making for more pleasant conditions. The air becomes drier, with less precipitation and lower levels of condensation.

Wind Patterns in Sertaozinho, Brazil

Sertaozinho, located in the southeastern region of Brazil, experiences distinct wind patterns influenced by its geographical location and seasonality. During the austral summer (December to February), a predominantly easterly flow prevails, known as the South Atlantic Convergence Zone (SACZ). The SACZ brings moisture-laden air from the Atlantic Ocean, resulting in frequent precipitation and strong, gusty winds. The winds during this period are characterized by their variability and can reach speeds of up to 30 kilometers per hour.

In contrast, during the austral winter (June to August), Sertaozinho experiences weaker winds associated with the South Atlantic High. This high-pressure system stabilizes the atmosphere, leading to a decrease in precipitation and wind speeds. The prevailing winds during this period are predominantly southerly and have speeds ranging from 10 to 20 kilometers per hour. Additionally, local topography plays a significant role in shaping the wind patterns in Sertaozinho. The presence of the Serra da Mantiqueira mountain range to the west acts as a barrier to the easterly winds, resulting in weaker winds on the western side of the city.
