What Defines a "Sunny" College? Unpacking the Metrics

When we talk about "sunniest colleges," we're not just relying on a feeling. We're looking at hard data, primarily focused on two key metrics:

1. Average Annual Clear Days: This refers to the number of days per year where the sky is predominantly clear or mostly sunny, with minimal cloud cover.
2. Total Annual Sunshine Hours: This measures the cumulative hours of direct sunlight a location receives throughout the year.

These statistics, often sourced from meteorological agencies like the National Oceanic and Atmospheric Administration (NOAA), provide a robust framework for identifying consistently bright regions. While total precipitation and average temperatures are also considered, our primary focus remains on the sheer volume of sunshine. It's important to note that even in sunny climates, factors like humidity, seasonal variations, and the presence of urban heat islands can influence the perceived comfort. Understanding the UV index, often monitored by the Environmental Protection Agency (EPA), is also crucial for sun safety in these regions.
