Cities with Tropical Savanna Climate
The tropical savanna climate (Köppen Aw) is a dry-winter variant of the tropical climate zone, found on either side of the equatorial rainforest belt. It spans vast areas of West and East Africa, the Indian subcontinent, northern Australia, and parts of Central and South America—including the Caribbean coast of Mexico, Cuba, and the Brazilian highlands. The defining feature is a pronounced dry season during the low-sun period (usually winter) and a rainy season during the high-sun period (summer). Temperatures remain high year-round, with monthly means above 18°C, but the seasonal rainfall contrast creates a landscape that transforms from parched brown in the dry months to lush green when the rains arrive. This climate supports savanna grasslands with scattered trees, ideal for grazing animals and subsistence farming.

About Tropical Savanna climate
The tropical savanna climate corresponds to Köppen code Aw: tropical, dry-winter. The primary criterion is a mean monthly temperature of at least 18°C every month, paired with a distinct dry season where the driest month receives precipitation less than 60 mm and also less than 100 − (total annual precipitation in mm / 25). In practice, this means the dry season is clearly defined, often lasting four to six months. Unlike the tropical monsoon (Am) climate, which also has a dry season but still receives enough rain in the driest month to support forest, Aw experiences a real water deficit. The precipitation pattern typically shows a rainy season lasting from late spring to early autumn, followed by a dry winter. Total annual rainfall ranges between 800 and 1,500 mm, with the wet season contributing the vast majority. Temperatures average between 25°C and 30°C year-round, though the dry season often feels slightly cooler due to clearer skies and lower humidity.
Seasonal contrasts are sharp. During the dry season (often November to April in the Northern Hemisphere), skies are clear, humidity drops, and daytime highs can exceed 35°C. The landscape becomes dusty, and water sources shrink. In the rainy season (May to October), torrential afternoon thunderstorms are common, humidity rises to 80–90%, and the temperature moderates to around 24–28°C. For example, Mumbai, India, receives about 2,000 mm of rain annually, 80% of it falling between June and September, while January averages only 2 mm. Havana, Cuba, gets roughly 1,200 mm, with a pronounced dry season from November to April. The wet season brings lush vegetation but also flooding and mosquito-borne diseases.
For travel, the best time to visit depends on activity. The dry season (winter and early spring) offers sunny skies and lower humidity, ideal for wildlife viewing in savanna reserves like Kenya’s Maasai Mara or India’s Kanha National Park. Pack lightweight clothing in natural fabrics, a sun hat, sunscreen, and insect repellent. The rainy season (summer) can be challenging for travel due to daily downpours, but landscapes are green and waterfalls are full; lightweight rain gear and waterproof footwear are essential. Notable cities with Aw include Mumbai (India), Havana (Cuba), Veracruz (Mexico), and Dakar (Senegal). Mumbai experiences a heavy monsoon, with intense rains and occasional flooding, while Havana’s dry season is more moderate, making it pleasant for beach visits. Veracruz sits on the Gulf of Mexico and has a steamy wet season, while Dakar on the Atlantic coast benefits from a moderating ocean breeze, reducing extreme heat.
Často kladené otázky
Where does tropical savanna climate occur?
The Aw climate is found predominantly in West and East Africa, the Indian subcontinent, northern Australia, and parts of Central and South America. Specific areas include central India (e.g., Mumbai), the Caribbean coast of Mexico and Cuba, the Brazilian highlands, and the Sahel region of Africa.
What is the difference between Aw (tropical savanna) and Am (tropical monsoon)?
Both have a dry season, but Am receives at least 60 mm of rain in the driest month, while Aw drops below that threshold. Aw also has a longer, more severe dry season, often lasting four to six months, compared to Am's shorter dry spell.
Is a tropical savanna climate good for travel?
Yes, especially during the dry season (winter) when weather is sunny and humidity low. Many savanna regions are prime destinations for wildlife safaris and beach holidays. However, the wet season brings heavy rains and increased insects, which may deter some travelers.
What is the best time to visit a tropical savanna destination?
The dry season is ideal for most activities. For Northern Hemisphere locations (e.g., India, Cuba), this is typically November to April. For Southern Hemisphere savannas (e.g., Australian Top End), the dry season runs from May to October.
What should I pack for a tropical savanna climate?
For the dry season, pack light, breathable clothing, a hat, sunglasses, sunblock, and a refillable water bottle. For the rainy season, add a lightweight waterproof jacket, quick-dry pants, and mosquito repellent. Sturdy walking shoes are useful in both seasons.
Do all cities with an Aw climate experience the same seasons?
No. While all have a dry winter and wet summer, the exact timing and intensity vary. For instance, Mumbai’s rainy season is a dramatic monsoon, whereas Havana’s dry season is milder, and Veracruz experiences a brief but intense wet period. Latitude and proximity to water also affect temperature ranges.
