The map displays average daily maximum air temperatures in degrees Celsius across the contiguous United States over a 33-year period (1979-2011), using a five-tier color scale: light blue (<10°C), green (10-15°C), yellow (15-20°C), orange (20-24°C), and red (≥24°C). Cooler regions dominate the northern and western states, while the Southeast and Southwest show consistently higher averages, especially Florida and southern Texas. Data is sourced and visualized by MetricMaps, emphasizing long-term climatic patterns rather than short-term anomalies.
