Spring in Walvis Bay feels calm and comfortable, making it pretty easy to enjoy the coastline without dealing with extreme heat or heavy downpours. You’ll usually see mild daytime temperatures hovering around 18°C to 22°C, with cool nights dropping to 10°C to 14°C, and barely any rain at all during the season.
The air stays dry, and the skies get clearer as spring moves along.
If you’re into outdoor activities, spring gives you long daylight hours and gentle breezes. The ocean starts to warm up a bit, and the wind, mostly from the south, adds a refreshing touch without getting annoying.
This mix of steady sunshine, low humidity, and light winds makes spring one of the most predictable times of year for planning time outside.
As you dig into the details, you’ll see how the season shapes everything from temperature shifts and rainfall patterns to wind dynamics and other local quirks that define Walvis Bay’s spring weather.
Overview of Spring Climate in Walvis Bay
Spring in Walvis Bay brings steady, mild weather shaped by the coastal desert landscape. You’ll notice cooler mornings, moderate daytime highs, and almost no rain, while daylight and wind patterns start to change as summer approaches.
Spring Months and Seasonal Context
Spring here runs from September through November, bridging the gap between cooler winter and the warmer summer months. During this stretch, daily highs average around 64–65°F (18°C), and lows sit near 50–56°F (10–13°C).
September usually feels cooler, while November warms up a bit. Daylight increases by nearly two hours over the season.
Sunrise comes earlier, and sunsets push later, so you get longer days to spend outside.
Rainfall is basically nonexistent, averaging 0.0 inches, so you’ll get dry skies almost every day. Most days are clear or partly cloudy, and winds average about 9 mph, usually blowing in from the south.
If you’re planning activities, expect cool mornings and comfortable afternoons. The ocean water temperature climbs from about 56°F (13°C) in early September to around 60°F (16°C) by late November, which affects the feel of the air along the coast.
Desert Climate Characteristics
Walvis Bay sits in a subtropical desert climate, shaped by the Benguela Current off Namibia’s west coast. This cold ocean current keeps the air cool and dry, so heavy rain almost never happens.
Annual precipitation is extremely low, usually less than 10 mm.
Humidity rarely shows up in spring, with dew points staying low. The air feels crisp and dry, even when temperatures rise, which is a big difference from tropical places.
Fog pops up a lot in the mornings because cold ocean air clashes with warmer inland air. Usually, that fog burns off by midday, leaving bright skies.
The desert climate also means strong sun. Even though air temperatures stay mild, the UV index can get high, so you’ll want to use sun protection if you’re outside for long.
This combination of cool ocean influence, almost no rain, and strong sun really defines spring in Walvis Bay and sets it apart from Namibia’s inland regions.
Average Daytime Temperatures in Spring
Spring in Walvis Bay brings mild, steady weather. Daytime highs stay comfortable, and nights are cool but not too chilly.
You’ll notice a gradual warming trend from early September to late November.
Typical Daily Highs and Lows
During spring, average daytime highs in Walvis Bay stick around 64–65°F (18–19°C). Highs rarely jump above 75°F (24°C) or drop below 57°F (14°C), so afternoons feel pleasant, not hot.
Nighttime lows creep up as spring goes on. Early in the season, lows can dip to 50°F (10°C), but by late November, they get closer to 56°F (13°C).
Nights stay cool, so you might want a light jacket, especially near the water.
The difference between day and night temperatures is pretty small, about 10–15°F. This limited swing means you won’t get big shifts in comfort. The cool Benguela Current keeps the climate stable and prevents extreme heat.
Monthly Temperature Variations
In September, daytime temperatures average about 64°F (18°C), and evenings cool off to around 50°F (10°C). That’s the chilliest part of spring.
By October, things warm up a bit. Highs reach 65°F (19°C), and lows climb to 53°F (12°C). The changes are slow and steady, so you won’t get any weather whiplash.
November keeps the warming trend going. Highs often hit 66–67°F (19–20°C), and lows stay near 55–56°F (13°C). November is usually the warmest spring month in Walvis Bay.
Overall, both highs and lows rise steadily, so you can count on mild afternoons and cool evenings all spring, with the warmest days coming just before summer.
Rainfall and Precipitation Patterns
Walvis Bay gets very little rain all year, and spring is no exception. You’ll see only a few brief showers, with most days dry and clear.
Average Rainy Days in Spring
Expect almost no rainy days during spring in Walvis Bay. On average, the city logs just 1 to 2 days per month with measurable precipitation between September and November.
Even when it does rain, it’s usually light and doesn’t last long.
This is just how coastal desert climates work. Moisture from the Atlantic mostly arrives as fog, not rain, so you’ll notice damp mornings more often than actual showers.
Because rain is so rare, outdoor plans almost never get interrupted. Spring is a favorite for birdwatching at the lagoon or exploring the dunes.
Seasonal Precipitation Amounts
Rainfall totals in spring are tiny. Across all three months, Walvis Bay usually gets less than 10 mm of rain. Some years, it doesn’t rain at all.
The wettest time of year comes in late summer, so spring falls in the driest part of the cycle. For example, February averages about 7 mm, while September through November often stay close to 1–3 mm each month.
This lack of rain really highlights the desert climate. Instead of showers, you’ll see fog rolling in from the cold Benguela Current, which brings moisture without adding to the rain totals.
That fog actually matters a lot for local plants and wildlife, since it’s a key source of water.
Humidity Levels During Spring
Even though Walvis Bay sits in a desert, humidity stays pretty high during spring. The cool Benguela Current offshore keeps the air moist, shaping both the weather and what you can comfortably do outside.
Relative Humidity Trends
During spring, relative humidity in Walvis Bay usually ranges between 80% and 85%. These numbers don’t shift much from September to November.
Unlike inland Namibia, where humidity can drop off fast, Walvis Bay’s spot on the coast keeps things damp year-round. The ocean keeps big swings in check, so you won’t get sudden drops in moisture.
Morning and evening hours feel the dampest. Fog is common, especially in October, when cool nights and moist air mix together.
This fog keeps humidity high, even though rain is almost nonexistent.
The air can feel heavy at times, but the mild spring temperatures help balance it out. Highs usually stay between 19°C and 23°C (66°F to 73°F), so the humidity isn’t as tough to handle as it would be in hotter places.
Impact on Comfort and Activities
High humidity changes how you feel the mild temperatures. A 21°C day might feel warmer than the thermometer says because moisture in the air slows down how well your body cools off.
If you’re planning outdoor stuff like walking along the lagoon or birdwatching, mornings can feel cool but damp thanks to fog. By midday, things clear up, and it feels more comfortable.
Sports like kayaking or sailing actually benefit from the moist air, since it keeps harsh heat away.
Drying clothes or gear might take longer, though, since moisture tends to stick around.
If you have breathing sensitivities, the damp air can feel heavy, especially on foggy mornings. Still, the steady humidity makes it easier to plan outings because the weather doesn’t change much.
Wind Speed and Weather Dynamics
You’ll notice steady winds shaping the local climate and affecting daily life. Wind direction and speed stay pretty consistent, and this stability is one of Walvis Bay’s classic spring features.
Prevailing Wind Patterns
During spring, winds in Walvis Bay mostly blow from the south and southwest. The Benguela Current along the Atlantic helps keep the air cooler and drier.
These aren’t just occasional breezes—they’re a regular part of life here. Some days, the southern wind direction accounts for up to 75% of the time, so you’ll definitely notice it.
These winds help keep rain away through the season and also cut down on humidity, which is why muggy conditions just don’t happen much in spring.
For travelers, this means clearer skies and more comfortable time outdoors.
The steady winds also make activities like kitesurfing, sailing, and fishing more predictable. If you’re heading out on the water, expect regular afternoon breezes you can count on.
Monthly Wind Speed Averages
Wind speed in Walvis Bay stays remarkably stable during spring. Average speeds sit close to 9 miles per hour (14 km/h), with barely any variation.
On the windiest spring days, speeds can reach about 9.3 mph in early October. Even on calmer days, there’s always a gentle movement around 8–9 mph, so it never really gets totally still.
Here’s a quick breakdown of average wind conditions:
| Month | Average Wind Speed | Dominant Direction |
|---|---|---|
| September | ~9.0 mph | South-Southwest |
| October | ~9.3 mph (peak) | South |
| November | ~9.0 mph | South-Southwest |
This steady pattern means you can plan with confidence, whether it’s for outdoor events, port activities, or coastal excursions.
The climate here doesn’t throw you sudden gusts or big wind changes in spring, so you get a reliable sense of what’s coming.
Other Notable Spring Weather Features
Spring in Walvis Bay brings longer daylight hours, steady winds, and mild ocean temperatures. You’ll notice more sunshine compared to winter, but the cool Benguela Current keeps things stable and prevents any real heat waves.
Sunshine Hours and Cloud Cover
During spring, you gain almost two extra hours of daylight from September through November. Early in the season, days last about 11 hours and 40 minutes, and by late November, you’re looking at over 13 hours.
Sunrises come earlier and sunsets push later, which gives you more time for outdoor adventures.
Clear skies rule most days. In September, the sky is clear or mostly clear about 90% of the time, making it one of the brightest months. By November, there’s a slight bump in cloud cover, but overcast days are still rare.
Rain is almost never a factor. The average precipitation hangs near 0.0 inches, so you don’t really need to worry about rain messing up your plans.
This dry, sunny climate means you can expect good visibility and reliable weather for travel, tours, and wildlife viewing.
Influence of the Benguela Current
The Benguela Current runs cold along Namibia’s coast, shaping Walvis Bay’s spring weather in a big way. It keeps the air mild, with highs usually between 64–71°F and lows hanging around 50–56°F.
If that current disappeared, I’d bet the desert would crank up the heat and dry things out even more.
Since the current cools the surface water, you’ll see sea temperatures creeping up from about 56°F in early September to maybe 60°F by late November. The ocean stays colder than the air, and that difference sometimes brings coastal fog in the mornings.
Winds usually blow in steady from the south. They average about 9 mph, and honestly, they can make afternoons feel chillier than you’d expect.
That breeze also keeps humidity down, so the air feels dry and pretty comfortable all season.
