UV index at 11.8 in Australia means extreme risk: limit outdoor time especially from 10 a.m. to 4 p.m., actively seek shade, wear protective clothing, broad-brimmed hat, apply SPF 30+ sunscreen every 2 hours, and wear UV-blocking sunglasses. Watch for bright surfaces like water and snow increasing UV exposure.
Mexico's UV index can range from moderate to very high, especially in sunny areas and during summer months. Coastal and high-altitude regions often experience higher UV levels year-round.
In Mexico, summer (May to September) is hot and rainy, while winter (November to February) is cooler and drier. The spring and autumn months are usually warm and pleasant with less rain.
Compared to other countries in North and Central America, Mexico generally has stronger sun and higher temperatures than northern neighbors like the US and Canada. It is sunnier and warmer year-round than much of Central America.
