Key Weather Factors in St. Augustine

Humidity Levels

St. Augustine's coastal location and subtropical climate contribute to consistently high humidity levels, particularly during the summer months. Relative humidity often exceeds 70% and can reach 90% during the peak summer afternoons. "Our analysis shows that understanding humidity is crucial for planning outdoor activities, as it significantly impacts perceived temperature and comfort," notes an environmental scientist. High humidity can make the heat feel more intense, a phenomenon often referred to as "heat index" or "feels like" temperature.

Precipitation Patterns

Precipitation is distributed fairly evenly throughout the year, but with a distinct peak during the summer. This summer rainfall is largely driven by convective thunderstorms fueled by heat and moisture. These storms can produce heavy downpours, leading to localized flooding, especially in low-lying areas. According to the National Weather Service, "understanding localized heavy rainfall potential is key for St. Augustine residents to avoid flash flood risks."

Wind and Breezes

Coastal breezes are a common feature of St. Augustine's weather, offering some relief from the heat and humidity, especially along the beaches and near the Intracoastal Waterway. However, these same winds can be a factor during severe weather events. During hurricane season, strong winds associated with tropical systems pose a significant threat, capable of causing widespread damage.

Sunshine and Cloud Cover

St. Augustine enjoys a considerable amount of sunshine throughout the year. While summer afternoons often feature cloud buildup and thunderstorms, mornings are typically sunny. Winter months generally offer the clearest skies. The high number of sunny days makes it an attractive destination year-round, but it also necessitates consistent sun protection. — 345 Adams Street, Brooklyn: Civil Court & Visitor Guide
