Weather & UV Protection
While checking the weather forecast is important for planning outdoor activities, it's also crucial to consider UV exposure, which can be high even on cloudy days. Here are some sun protection tips based on weather conditions:
- Sunny days: Use SPF 30-50+ sunscreen, wear a hat, sunglasses, and seek shade during peak hours (10am-4pm)
- Cloudy days: Up to 80% of UV radiation can penetrate cloud cover - continue to use SPF 30+ sunscreen
- Rainy days: UV rays can still reach you through clouds - apply sunscreen to exposed skin when outdoors
- Windy conditions: Wind can reduce the sensation of sun exposure, potentially leading to unexpected sunburn
