Climate & Weather Guide
Climate zones, seasonal temperatures, rainfall patterns, and best travel times in Botswana
Botswana features a semi-arid to arid subtropical desert climate with hot summers, mild winters, and highly variable rainfall concentrated from October to April. Winters from May to August are dry, sunny, and cool at night with occasional frost, while summers from November to March bring intense heat up to 38°C and moderate rains. Annual precipitation ranges widely from under 250mm in the southwest Kalahari to over 500mm in the northeast, influenced by convective storms. Low humidity and large diurnal temperature swings characterize the country, with climate change intensifying droughts and heat. Ideal for expats seeking sunny, wildlife-rich environments but requiring adaptation to water scarcity and heat.

Regional Climate Variations
Southwestern Kalahari
The driest region in the Kgalagadi district receives very low rainfall under 250mm annually, dominated by hot desert conditions. Summers soar above 35°C with minimal precipitation, while winters feature mild days around 25°C and cold nights dipping to near freezing with frost. Vast sandy expanses and sparse vegetation define this arid zone, where dust storms occur in spring. Expats appreciate the clear skies and wildlife but must prepare for extreme aridity and heat.
Intensely hot days with chilly nights, bone-dry air, and endless sunny horizons perfect for desert adventures yet challenging for water-dependent living.
Central Kalahari Basin
Semi-arid steppe climate prevails with low rainfall of 250-500mm, supporting savanna grasslands that green briefly after rains. Hot summers reach 35°C with erratic convective showers from November to March, transitioning to dry winters with daytime highs of 24°C and frosty nights around 5°C. The flat basin experiences strong winds and dust in late winter. Residents enjoy abundant sunshine and game viewing but face prolonged dry spells and variable water availability.
Warm, sunny, and mostly dry with dramatic seasonal shifts from dusty aridity to lush post-rain savanna, ideal for safari enthusiasts.
Northeastern Okavango and Chobe
Higher rainfall up to 600mm supports denser mopane woodlands and wetlands around the Okavango Delta. Summers are hot and humid at 30-35°C with reliable rains fueling floods, while winters offer comfortable 25°C days and cool 10°C nights, perfect for wildlife viewing. This wetter zone sees more thunderstorms but remains subtropical desert-like overall. Expats value the biodiversity and milder conditions but note mosquito risks during wet seasons.
Hot, steamy summers yielding to crisp, dry winters amid lush deltas teeming with life, offering a vibrant contrast to the arid south.
Southeastern Hardveld
Around Gaborone, low to moderate rainfall of 500mm falls in summer, with rocky hills hosting acacia savannas. Temperatures peak at 34°C in hot, rainy Nov-Mar, cooling to mild 23°C days and 6°C nights in winter with frost risks. More populated and urbanized, it experiences similar aridity but slightly wetter conditions. Practical for residents with better infrastructure, though droughts impact agriculture and water supply.
Balanced warmth with seasonal rains greening the landscape, comfortable for urban living yet punctuated by dry, frosty winters.
Botswana's climate spans hot desert in the arid southwest to hot-summer steppe in wetter northeast, with hot summers, cool dry winters, and low erratic rainfall posing drought risks amid abundant sunshine. Expats and residents are drawn to the sunny, wildlife-filled savannas and mild winters, but must adapt to heat, water scarcity, and increasing climate variability for comfortable living.
