Beach & Swimming Conditions
Weather index for activity planning
What is the Beach & Swimming Conditions?
The Beach & Swimming Index provides a comprehensive assessment of ideal weather conditions for enjoying beach activities, including swimming, sunbathing, water sports, and coastal recreation. This index considers air temperature (with ideal range between 24-32°C for maximum comfort), precipitation (rain can make the experience unpleasant and increase safety risks), wind speed (strong winds can create dangerous waves and make the apparent temperature uncomfortable), and UV index (crucial for protection against sunburn and skin damage). Ideal conditions combine mild temperatures, clear or partly cloudy skies, light winds, and adequate UV protection, creating the perfect environment for a safe and enjoyable day at the beach.
How is the Beach & Swimming Conditions calculated?
- Air temperature: Temperatures between 24-32°C (75-90°F) are ideal and increase the index, providing maximum comfort for beach activities. Temperatures below 20°C (68°F) or above 35°C (95°F) reduce the index due to thermal discomfort.
- Precipitation: Rain significantly reduces the index, making the experience unpleasant and increasing safety risks, especially during storms with lightning. Dry conditions score highest.
- Wind speed: Light winds (up to 15 km/h or 9 mph) are ideal and increase the index. Strong winds (above 25 km/h or 15 mph) reduce the index, creating dangerous waves for swimming and making the apparent temperature uncomfortable on the beach.
- UV index: Moderate UV values (3-6) are acceptable with adequate protection. Very high values (8+) reduce the index due to increased risk of sunburn, requiring extra protection and limiting exposure time.
