View the complete 2025 seasonal calendar. Find the exact start dates for Spring, Summer, Autumn, and Winter in the Northern and Southern Hemispheres.
2025 Seasonal Start and End Dates for Northern and Southern Hemispheres =======================================================================
The upcoming calendar year begins firmly in the Northern Hemisphere's winter, with the vernal equinox scheduled for March 20. This date marks the astronomical start of spring. For inhabitants of the Southern Hemisphere, this same period is the height of their summer, a time defined by maximum solar radiation and extended daylight. Planning should account for these diametrically opposed climatic conditions depending on your global position.
Key astronomical transitions define the year's progression. The summer solstice arrives on June 21, bringing the longest period of daylight to northern latitudes. Following this peak, the autumnal equinox on September 22 signals the beginning of fall and a noticeable shortening of days. The cycle's cold phase is initiated by the winter solstice on December 21, the point of minimum daylight in the Northern Hemisphere.
Leveraging these dates is a practical tool for planning. For agricultural activities in temperate northern zones, the period following the March equinox is optimal for planting. In contrast, travel planning for equatorial regions should consider that the months following the equinoxes often correspond with peak rainy periods. Using these four celestial markers provides a dependable structure for organizing personal and professional schedules throughout the twelve-month cycle.
Pinpointing the Start of Each Season in Brazil for 2025
The astronomical commencements for Brazil's four distinct climatic phases during the forthcoming year are precisely defined. These dates mark the official transition based on the Earth's position relative to the sun, influencing daylight hours and broad weather patterns across the nation's diverse regions.
Outono (Autumn): The shift away from the hot, wet period begins on March 20. The equinox occurs at 06:01 Brasília Time (BRT). This point signals a gradual decrease in rainfall for the Southeast and Central-West regions. In the South, temperatures begin their descent, while the Northeast largely maintains its warmth with reduced precipitation.
Inverno (Winter): The year's shortest day arrives on June 21, with the solstice officially starting at 00:42 BRT. Expect dry air and the lowest temperatures, particularly in the southern states like Rio Grande do Sul and Santa Catarina, where frosts are common. The Amazon region concurrently experiences its 'vazante' or low-water period.
Primavera (Spring): The return of longer days is marked by the equinox on September 22 at 15:19 BRT. This phase initiates the return of rains to the Central-West and Southeast. It is a time of flowering across the country, most notably in the national parks of the Cerrado biome and the city of Holambra.
Verão (Summer): The longest day of the year inaugurates the hottest quarter on December 21. The solstice event is at 12:03 BRT. This period is characterized by heavy, often daily, afternoon thunderstorms in the Southeast. The Northeast's coastline enjoys peak beach weather, while the Amazon enters its high-water, or 'cheia', period.
Seasonal Climate and Weather Patterns by Brazilian Region for 2025
For travel planning during the approaching annual cycle, prioritize Brazil's Northeast between August and November for minimal rainfall and consistent sunshine. The South region requires preparation for near-freezing temperatures in its winter period.
North Region (Norte)
The North Region anticipates a prolonged wet period, extending from January through late June. Expect daily heavy downpours, particularly in the afternoons, with precipitation levels potentially exceeding 300mm per month in states like Amazonas and Pará. From July onwards, a drier atmospheric pattern establishes, though high humidity persists. Temperatures will remain stable, hovering between 24°C and 32°C throughout the year.
Northeast Region (Nordeste)
Coastal areas of the Northeast, from Bahia to Maranhão, will see concentrated rainfall from April to July. The interior, or sertão, will face arid conditions with temperatures frequently surpassing 35°C, especially in the second semester. Wind patterns will be strong along the coastline, particularly in Ceará and Rio Grande do Norte, creating ideal conditions for kitesurfing from August to December.
Central-West Region (Centro-Oeste)
The Central-West is defined by two sharp climatic periods. A rainy summer from October to March will bring intense thunderstorms, replenishing the Pantanal wetlands. Following this, a pronounced dry spell takes hold from May to September. During this dry period, air humidity can drop below 20%, and daytime temperatures in Cuiabá and Campo Grande often reach 37°C. The risk of wildfires increases significantly after July.
Southeast Region (Sudeste)
Summer months in the Southeast (December through March) will be characterized by hot, humid days and afternoon electrical storms, especially in Minas Gerais and São Paulo. Temperatures can peak near 38°C in Rio de Janeiro. The winter period, from June to August, is predominantly dry and mild, with daytime temperatures between 18°C and 25°C. São Paulo may experience periods of fine, persistent drizzle known as garoa.
South Region (Sul)
Brazil's South will experience the most defined atmospheric changes. https://billybillioncasino.de are warm and humid. The winter, from June to September, will be the coldest in the country. Prepare for temperatures dropping to near 0°C in the highlands of Santa Catarina and Rio Grande do Sul, with a high probability of frost. Cold fronts, or friagens, will be frequent, causing sudden temperature drops. Spring is often marked by variable weather, including rain and wind.
Aligning Travel and Local Events with Brazil's 2025 Seasonal Calendar
Target the January to March period for coastal exploration along the Costa Verde between Rio de Janeiro and São Paulo, where lush vegetation peaks after spring rains. For a unique cultural fixture, attend Salvador's Festa de Nosso Senhor do Bonfim in January, a celebration blending Catholic and Candomblé traditions. This time offers a less crowded alternative to the main Carnival cities for beach-focused trips.
Between April and June, cooler and drier conditions in the interior make it the prime window for trekking in Chapada Diamantina National Park. The waterfalls are still full, but trails are more accessible. Coincide a trip to the Northeast with the Festas Juninas in June. Cities like Campina Grande and Caruaru host immense multi-week festivals celebrating rural life with specific foods, music, and quadrilha dances.
For optimal wildlife viewing, schedule a visit to the Pantanal from July through September. The dry spell concentrates fauna around the remaining water sources, greatly increasing chances of spotting jaguars and capybaras. For a contrasting urban experience, visit the mountain city of Gramado in August for the Festival de Cinema de Gramado, Latin America's premier film festival, offering a taste of Southern Brazil's European heritage.
From October to early December, witness the dramatic floral blooms in Minas Gerais. The historic towns of Ouro Preto and Tiradentes are set against a backdrop of colorful flowering ipê trees. This period also hosts Blumenau's Oktoberfest, the largest German festival outside of Germany, offering a distinct cultural experience in Santa Catarina with parades, folk music, and traditional attire.
