Overview of Tamanrasset’s Climate
Tamanrasset sits deep in the Algerian Sahara, where high elevation, desert dryness, and big swings in daily temperature really define the weather. You get mild winters, scorching summers, and almost no rain. The altitude and nearby mountains add some subtle seasonal changes.
Geographical Setting
Tamanrasset stands about 1,370 meters (4,500 feet) above sea level, right in the Hoggar Mountains of southern Algeria. This elevation sets it apart from most other desert cities at lower heights.
The city is south of the Tropic of Cancer, smack in one of the Sahara’s driest patches. Even so, the surrounding mountains create a bit of a microclimate, softening both the daytime heat and nighttime chill compared to flatter deserts.
Because of the elevation, nights often get cold even if the days feel warm. In winter, this contrast really stands out, and temperatures can fall close to freezing after sunset.
The geography limits rainfall, too. Sometimes, summer storms tied to the African monsoon bring short showers, but those are rare and only add a little humidity in late summer.
Desert Climate Characteristics
The climate here is subtropical hot desert (BWh). You’ll find long stretches of sunshine, barely any humidity, and almost no rain all year.
Average yearly rainfall is just 55 mm (2 in), spread over fewer than 20 days. Most months hardly see a drop, with August and September getting just a bit more.
Days are usually dry and clear, and humidity ranges between 14% and 24% depending on the time of year. This dryness makes even hot days feel less stifling, but it also means nights cool off fast.
Winds play a big role, too. They usually blow at 11–16 kph, though sometimes you’ll get stronger gusts. The wind helps clear out heat but can kick up dust, especially in the driest months.
You’ll notice sharp differences between day and night—warm afternoons, cool evenings. That daily temperature swing is one of the most striking things about living or traveling here.
Annual Weather Patterns
Temperatures swing a lot through the year, but the altitude keeps the extremes in check. January, the coldest month, usually sees 5°C (41°F) at night and 20°C (68°F) during the day. Sometimes, nights dip below freezing.
In July, the hottest month, nights average 24°C (75°F), and days reach 36°C (97°F). Temperatures above 40°C (104°F) happen, but not as often as in lower parts of the Sahara.
Rain is scarce all year. The wettest months—August and September—only get 7–8 mm each. Driest months like November might not get any rain at all.
Daylight and sunshine matter, too. In winter, you’ll get nearly 11 hours of daylight, and more than 13 hours in summer. That means sun is almost always on the menu.
With mild winters, hot summers, and barely any rain, Tamanrasset’s climate stands out in the Sahara. You get a mix of desert extremes and mountain moderation.
Typical Winter Weather in Tamanrasset
Winter brings mild daytime warmth, cool nights, and almost no rain. Skies stay clear for most of the season, and dry air plus steady winds shape the feel of the desert.
Average Winter Temperatures
Daytime winter temperatures usually feel just right. Highs hit about 68–72°F (20–22°C), which is a relief after the summer heat. The coldest January days might only reach 68°F (20°C), while warm spells can climb to 81°F (27°C).

This mix of mild days and cool nights makes winter the most comfortable time to be outside in Tamanrasset.
Day and Night Temperature Variations
You’ll definitely notice the difference between day and night. The desert lets heat escape fast after sunset, so temperatures can fall by 20–25°F (11–14°C) in just a few hours.
For example:
| Time of Day | Typical Temperature |
|---|---|
| Afternoon | 68–72°F (20–22°C) |
| Night | 42–45°F (6–7°C) |
You might want light clothes for the day but something warmer after dark. The dry air really amplifies this, since there’s not much moisture to keep the heat in.
The coldest nights usually pop up in January. By late February, things start to warm up a bit as the days get longer.
Humidity and Wind Conditions
Humidity stays low all winter. Dew points often sit below 32°F (0°C), so the air always feels dry, never sticky. This dryness keeps cool temperatures crisp instead of clammy.
Rain is almost unheard of. There’s only about a 1% chance per day of any measurable precipitation, and the total for the season is just 0.1 inches (2–3 mm).
Winds blow steadily and can feel brisk out in the open. Average speeds climb from 8 mph to about 10 mph, usually coming from the east. Strong winds aren’t common, but dust can get whipped up in exposed spots.

Precipitation and Cloud Cover During Winter
Winter in Tamanrasset means almost no rain and mostly dry skies. Cloud cover drops steadily through the season, and snow just doesn’t happen because of the desert climate and elevation.
Rainfall Patterns
You’ll rarely see measurable rain in winter. A “wet day” (at least 1 mm of rain) only happens on about 1% of days. Most weeks go by without a single drop.
Rainfall totals barely change through December, January, and February. The 31-day sliding average is about 3 mm, hitting a low of 1 mm in early January. Even in wetter years, monthly totals hardly ever top 14 mm.
For reference, the rainiest part of the year is late summer, especially August, when the odds of rain rise to about 10%. In winter, the air stays dry and storms are almost never an issue.
Cloud Cover Trends
Cloud cover shifts more than rainfall does. Early December brings overcast or mostly cloudy skies about 40% of the time. By late February, that drops to around 27%, so the season gets sunnier as it goes.
The cloudiest day usually falls on December 1, while the clearest day is February 28, when skies are clear, mostly clear, or partly cloudy almost 73% of the time. That means you’ll see more bright days as winter goes on.
Unlike humid coastal areas, Tamanrasset’s dry desert air keeps thick clouds from forming. Most days are clear or just lightly clouded, so sunlight is strong whenever it’s up.
Rarity of Snowfall
Snow basically never falls in Tamanrasset. The city sits at 1,372 meters, high enough for cold nights but still in a hot desert climate (BWh).
Winter lows usually stay around 5–7°C, and even the coldest nights rarely drop below 2°C. That’s well above freezing, so snow just isn’t on the table.
If you’re planning a winter visit, you can count on dry, snow-free weather. Northern Algeria’s mountains might get a dusting, but Tamanrasset is all about arid desert conditions throughout the season.
Impact of Microclimate on Daily Life
The winter climate in Tamanrasset means cool nights, mild days, and big swings between the two. These conditions shape how you manage your home and plan your time outside.
Home Heating and Insulation
At night in winter, temperatures often get close to freezing, but daytime readings bounce back to comfortable levels. This sharp contrast means your house has to handle both cold nights and warmer afternoons.
Most homes use thick adobe or stone walls that naturally insulate against these changes. These materials help keep the inside warmer at night and cooler during the day, so you don’t need constant heating. Still, on the coldest nights, you might use a small gas or electric heater.
Simple tricks—like sealing window gaps, hanging heavy curtains, and tossing rugs over tile floors—help keep the warmth in. Dampness isn’t a problem here, but dust and dry air can make things less comfortable indoors.
Since you don’t need much heating and only for a short time, your energy use in winter stays pretty low. Good insulation and passive design matter more than big heating systems.
Gardening and Outdoor Activities
The desert microclimate really limits gardening, but winter actually gives you the best shot. Cooler days and those rare bits of rain mean you can finally tend a home garden without melting in the summer heat.
Focus on hardy plants that handle dry soil, like olive trees, figs, or drought-resistant veggies. You’ll still need to irrigate, but winter makes things easier since water evaporates less quickly.
Getting outside for a walk or exploring the nearby landscape feels so much nicer this time of year. The midday sun warms you up but doesn’t get overwhelming, while mornings and evenings can get a bit brisk.
Wearing light layers helps you adjust fast as the temperature changes.

If you’d rather skip the crowds, try November or March. Days get a bit warmer, nights stay cool, and rain is still pretty rare.
Packing Recommendations
Pack with those big day–night temperature swings in mind. Light clothes work great for the day, but you’ll definitely want layers at night. Bring a warm jacket, sweater, and long pants for when the sun goes down.
A scarf or head covering helps with sun and the occasional gust of wind. Sunglasses and sunscreen are must-haves since the desert sun doesn’t mess around, even in winter.
You’ll want sturdy, comfy shoes for rocky ground. Planning to hike in the Hoggar Mountains? Boots with ankle support make a difference.
Since the air is so dry, pack lip balm and moisturizer. A reusable water bottle comes in handy too—staying hydrated matters, even when it feels cool.
Seasonal Activities
Winter really stands out as the best season for desert excursions. You can wander around the Hoggar Mountains, climb Mount Tahat, or hop on a guided tour into the Sahara without worrying about brutal heat.
Clear skies make stargazing incredible here, since hardly any light pollution gets in the way. Local guides actually run night tours just for this, and honestly, it’s worth staying up late for.
During the day, you’ll find it’s comfortable enough to stroll through Tamanrasset’s markets. There, you can pick up Tuareg crafts or try some local foods.
Cultural tours and trips to nearby villages also become much more enjoyable thanks to the cooler weather.
If hiking’s your thing, winter gives you safe conditions to explore rocky plateaus and valleys. Just keep in mind, temperatures drop fast after sunset, so it’s smart to head back before it gets dark.
