Report ID: BRA-TEMP-2026-01 Date: April 14, 2026 Author: Climate Analysis Unit Geographic Focus: Federative Republic of Brazil 1. Executive Summary Brazil, the largest country in South America, does not have a single uniform average temperature due to its vast territorial extent (8.5 million km²), varying altitudes, and diverse climatic influences. However, the national annual average temperature is approximately 24.7°C (76.5°F) .
