The country is characterized by warm temperatures year-round, with regional extremes ranging from mild subtropical averages (14–19°C / 57–66°F) in the south to hot equatorial averages (26–28°C / 79–82°F) in the Amazon and Northeast. Recent data (2023–2025) indicate a warming trend above the long-term average, consistent with global climate change patterns. | Metric | Value | |--------|-------| | Annual National Mean (1991–2020 baseline) | 24.7°C (76.5°F) | | Average Annual High | 28.9°C (84.0°F) | | Average Annual Low | 20.5°C (68.9°F) | | Warmest Month (National avg.) | September / October (~25.5°C / 77.9°F) | | Coolest Month (National avg.) | July (~23.5°C / 74.3°F) | | Record High (National, 2024) | 44.8°C (112.6°F) – Araçuaí, MG | | Record Low (National, historical) | -14°C (6.8°F) – Caçador, SC (1952) | Note: National mean is calculated by weighting data from INMET (Instituto Nacional de Meteorologia) across all biomes and populated areas. 3. Regional Breakdown of Average Temperatures Brazil’s climate is divided into five major regions. Below are the average annual temperatures by region (2020–2025 mean):

Seasonal Temperature Patterns Brazil is located mostly in the Southern Hemisphere, so seasons are reversed relative to the Northern Hemisphere. Seasonal Temperature Patterns Brazil is located mostly in
| Season (Months) | National Avg Temp (°C) | Characteristics | |----------------|----------------------|------------------| | (Dec–Feb) | 25.5 – 26.5 | High heat, heavy rain in most regions; heatwaves common (40°C+ in SE) | | Autumn (Mar–May) | 24.0 – 25.0 | Gradual cooling; still warm in North/Northeast | | Winter (Jun–Aug) | 22.5 – 23.5 | Mild in most areas; frost and occasional snow in the South | | Spring (Sep–Nov) | 24.5 – 25.5 | Rising temperatures; peak heat in Central-West and Southeast | Heatwaves: Between 2023 and 2025, Brazil experienced five major heatwaves, with November 2023 recording national average anomalies of +3.5°C above baseline. 5. Long-Term Trends (1961–2025) Data from INMET and Brazil’s National Institute for Space Research (INPE) show a clear warming trend. heavy rain in most regions
