Fall in Walvis Bay feels like a gentle shift from the hotter summer months into cooler, drier days. Expect mild afternoons with average highs between 64°F (18°C) and 69°F (20°C), and cooler nights that dip close to 50°F (10°C).
Rain barely makes an appearance. You might see a trace in March, but the season dries out fast, so you’ll get some of the clearest skies all year.
As fall rolls on, the air gets crisper and humidity drops. You’ll probably find it comfortable for wandering around town or heading out into the desert.
Daylight hours stay pretty steady, giving you plenty of time for outdoor stuff without the summer’s intensity.
Steady winds come in off the Atlantic, and rain basically stays away. Fall sets up a stable atmosphere, which makes planning easy.
Maybe you’re into birdwatching along the lagoon, want to take a boat trip, or feel like heading inland for a desert tour—fall’s weather usually has your back.
Overview of Fall Weather in Walvis Bay
Walvis Bay, right on Namibia’s coast, gets mild and steady fall weather thanks to the cold Benguela Current. You’ll notice moderate temps, almost no rain, and daylight hours that gradually shorten as the season goes on.
Typical Climate Characteristics
Fall in Walvis Bay stays cooler than what you’ll find inland. Average daytime highs reach about 70°F (21°C), while nighttime lows drop to 53–60°F (12–16°C).
You won’t see wild temperature swings, so the climate stays predictable and comfortable.
Humidity drops as fall goes on. Early in the season, it might feel a bit humid, but by late fall, those muggy days are pretty much gone.
The air feels dry and crisp, especially in the mornings.
Rain barely shows up. You’ll see the chance of measurable precipitation hover around 1% per day, and monthly totals rarely hit 0.1 inches.
The coastal desert climate doesn’t really allow for frequent showers.
Clouds thin out as fall progresses. Skies stay mostly clear, and May brings the brightest days.
That means strong sunlight during the day, even if the air feels mild.
Seasonal Weather Patterns
Daylight hours drop off quickly from early March to late May. You actually lose about 1 hour and 40 minutes of daylight during fall.
Sunrises get later, moving from around 6:57 AM in March to 7:35 AM by the end of May.
Winds pick up as fall moves along. Average speeds go from 7.9 mph to 8.7 mph, usually blowing in from the south.
That steady breeze keeps temperatures in check but can make it feel cooler near the water.
Ocean temperatures cool down from 63°F (17°C) at the start of fall to about 58°F (14°C) by the end.
If you’re thinking of swimming or doing water sports, brace yourself for chilly water, especially in late fall.
Comparing Fall to Other Seasons
Compared to summer, fall feels drier and less humid. Summer brings more humidity, but by fall, those sticky days fade away.
The cooler ocean current gives the air a fresher feel.
Winter in Walvis Bay gets a bit cooler than fall, with average highs in the mid-60s°F.
Both fall and winter share that dry climate and very little rain. You might notice the wind picks up even more in winter.
Spring starts to warm up, but you’ll see more clouds and the occasional fog then, compared to fall.
Fall really stands out for clear skies and lots of sunshine.
Average Temperatures During Fall
Fall in Walvis Bay keeps things mild and steady, especially compared to many other coastal regions.
Daytime highs stay comfortable, and nights cool off noticeably, giving you a clear difference between day and night.
Average Daytime Temperature Trends
During fall, average daytime temperatures in Walvis Bay hover around 70°F (21°C).
Highs almost never drop below 59°F (15°C) or climb higher than 84°F (29°C), so there aren’t many surprises.
The warmest part of fall comes in early April, when highs reach about 71°F (22°C).
By late May, those highs ease down a bit but stay in the same general range, so afternoons remain pleasant for getting outside.
The cold Benguela Current keeps things consistent, moderating coastal temperatures.
Unlike Namibia’s inland areas, where things can get extreme, Walvis Bay’s Atlantic spot means the climate rarely feels uncomfortable during the day.
Low Temperature Variations
Nighttime lows drop more than daytime highs. Early in fall, you’ll get lows near 60°F (16°C), but by the end, they’re closer to 53°F (12°C).
Sometimes, on chillier nights, temps can dip to 47°F (8°C), though that’s not the norm.
This steady decline means evenings and mornings feel cooler as the season goes on.
If you’re out after dark, you’ll probably want a light jacket, especially in May.
Walvis Bay’s dry air keeps things crisp at night. Lower humidity means muggy evenings are rare, and the cool nights actually feel refreshing.
Day and Night Temperature Differences
During fall, the gap between daytime highs and nighttime lows averages 10–15°F (5–8°C).
Afternoons climb into the upper 60s or low 70s, but nights cool off quickly once the sun goes down.
That swing is typical for coastal areas with desert influence. The ocean keeps extreme heat at bay, but dry inland air lets temperatures fall after sunset.
If you’re traveling, you’ll get warm afternoons perfect for lighter clothing, then cooler evenings where layers make sense.
The shift stays steady enough that you can plan ahead, knowing mornings start cool and afternoons warm up nicely.
Sunshine and Daylight in Fall
Fall in Walvis Bay brings slightly shorter days, but sunshine sticks around as a main feature.
Long bright periods and barely any rain give you solid odds for outdoor plans.
Sunshine Hours Per Day
You’ll get about 7 to 8 hours of sunshine per day in fall.
That’s just a small drop from the sunniest times of late spring and summer.
Daylight runs from about 11 to 12.5 hours, depending on the month.
Even when clouds show up, the coastal desert climate usually lets the sun break through.
Here’s a quick look at daylight and sunshine averages:
| Month | Avg. Daylight | Avg. Sunshine Hours |
|---|---|---|
| March | ~12.2 hrs | ~7.0 hrs |
| April | ~11.5 hrs | ~7.5 hrs |
| May | ~11.0 hrs | ~8.4 hrs |
You probably won’t lose a whole day to overcast skies.
Frequency of Sunny Days
Fall in Walvis Bay really delivers on sunny days.
Cloud cover drops as the season goes on. In March, about 19% of days might be mostly cloudy, but by May, that drops to around 8%.
So, most days are clear or partly sunny. Rain is almost nonexistent, with just the odd trace in some years.
The area sits in an arid coastal zone, so fog can show up in the mornings.
Usually, it clears pretty quickly, leaving bright skies for the rest of the day.
Impact on Outdoor Activities
With reliable sunshine, fall stands out as one of the best times for getting outside.
Long daylight hours mean you can plan activities like kayaking in the lagoon, birdwatching, or sand dune excursions without much worry.
Mild temperatures and steady sun keep heat stress low, which isn’t always the case inland.
If you’re into photography or sightseeing, the softer fall sunlight gives you great visibility.
Early mornings and late afternoons bring clear skies and less glare, making it comfy for both quick outings and full-day adventures.
Humidity and Fog Conditions
During fall, the air in Walvis Bay often feels damper than inland Namibia, and fog is a regular guest along the coast.
These factors shape how comfortable you feel outside and how far you can see, especially early in the day.
Average Humidity Levels
Humidity stays relatively high in Walvis Bay all year, thanks to the cold Benguela Current just offshore.
In fall, average relative humidity sits between 65% and 74%, with September usually hitting the top end.
The coast holds onto more moisture than inland spots, which helps explain why daytime temps feel cooler than the numbers suggest.
Here’s a quick breakdown:
| Month | Avg. Humidity |
|---|---|
| March | ~73% |
| April | ~66% |
| May | ~60% |
| June | ~58% |
By fall, humidity drops compared to summer, but it’s still high enough to keep the air moist.
You won’t get the dry, hot air that fills Namibia’s interior.
Occurrence of Fog
Fog really defines Walvis Bay’s weather, especially in fall.
You’ll often run into frequent morning fog from April through September.
The mix of cool ocean currents and warmer inland air makes this happen.
On average, expect about 4–5 fog days per month in fall.
The fog usually forms overnight and clears by late morning as the sun warms things up.
Sometimes, it’s not just a light mist. Dense fog layers can blanket the coast.
You might notice that while inland areas get sunshine, the bay stays foggy for a few hours.
Effects on Visibility
Fog can cut visibility down to just a few hundred meters, mostly in the early morning.
You might have trouble seeing far on the road or along the harbor.
Drivers need to keep headlights on, and ships in the port often rely on radar until the fog lifts.
By midday, things usually clear up.
Because of the high humidity and thick fog, plan outdoor activities for later in the day.
Morning boat trips could run into low visibility, but afternoons are generally much clearer.
Wind Patterns and Speeds in Fall
During fall, you’ll notice steady winds shaping the daily weather in Walvis Bay.
The direction, speed, and consistency of these winds really influence how cool or dry the air feels, and they matter for outdoor comfort.
Prevailing Wind Directions
In fall, winds usually blow in from the south and southwest.
They move inland from the Atlantic, bringing cooler air to the coast.
Walvis Bay’s open coastline means the wind direction stays pretty consistent.
You won’t see big shifts in wind patterns during fall. Instead, the breeze follows a reliable path tied to ocean pressure systems.
If you’re planning outdoor activities, this matters. Kiteboarders and sailors count on the southwesterly wind for steady conditions.
Even when things feel calm inland, the coast almost always has a steady sea breeze.
Average Wind Speed
Fall lands in the windier part of the year, which runs from late May through November.
Average speeds often go over 8–9 miles per hour (about 14 km/h), and some days bring even higher gusts, especially near the harbor or dunes.
Most afternoons come with a noticeable breeze. Mornings might start off calmer, but the wind usually picks up as the day goes on.
That’s typical for coastal Namibia, where warm land pulls in cool ocean air.
Wind speeds aren’t extreme by global standards, but they’re steady enough to make a difference.
If you’re out walking along the waterfront or exploring the lagoon, you’ll probably feel the wind almost every day.
Wind’s Effect on Weather Experience
Wind really shapes how you feel fall weather. Even with mild temperatures, a steady breeze will make the air feel cooler, especially after the sun goes down.
You’ll probably want a light jacket if you’re hanging around outside once evening hits. The wind also keeps humidity down.
In fall, you’ll notice the air isn’t as heavy or damp as in summer, and the constant breeze stops things from feeling muggy. This makes walking, cycling, or birdwatching around the lagoon way more pleasant.
If you’re traveling, wind can help or get in the way. It’s great for water sports, but sometimes it kicks up sand along the dunes.
I’d suggest checking wind direction and speed before planning your day. That way, you can really enjoy what the season offers.
Travel Considerations for Fall
Fall in Walvis Bay brings mild days, little rain, and steady southern winds. You’ll get cooler evenings, plenty of clear skies, and not much humidity.
It’s honestly a good season for outdoor plans or coastal trips.
Best Activities for the Season
Outdoor activities feel comfortable in fall, with highs near 70°F and hardly any rain. Clear skies and calm weather make lagoon tours and birdwatching easy to plan.
You’ll probably spot flamingos and pelicans hanging around the wetlands. Fishing trips keep running since the ocean stays stable.
If you’d rather stay on land, dune drives and sandboarding by the Namib Desert are popular picks. Cool evenings make these adventures less draining than in summer.
Water sports like kayaking and kite surfing are tempting too. Winds get stronger as fall goes on, which gives experienced surfers and sailors some good conditions.
Packing Tips for Visitors
Pack some light layers because mornings and nights get chilly, sometimes down to the low 50s°F. A light jacket or windbreaker comes in handy, especially near the coast where the breeze can be pretty sharp.
Bring comfy walking shoes for dunes and wetlands. If you’re heading into the desert, sand-resistant shoes are a smart move.
For water activities, quick-dry clothes and a hat with a strap will make things easier.
Don’t skip sun protection, even in fall. Sunscreen, sunglasses, and a wide-brimmed hat are must-haves.
The sun still packs a punch, and all that sand and water reflects even more light back at you.
Weather-Related Travel Advice
Rain barely shows up in fall—maybe a 1% chance on any given day. You probably won’t deal with storms, but honestly, that coastal fog in the morning can sneak up on you. If you’re driving early, give yourself some extra time for reduced visibility.
Daylight slips away fast as the season moves along. By late May, the sun’s already gone by 6:30 PM.
Try to wrap up outdoor plans before it gets dark, especially if you’re out in the desert or on the water.
Winds pick up later in the season, mostly in the afternoons. If you’re thinking about boat tours or kayaking, go earlier for calmer weather.
That way, you’ll also dodge windblown sand if you’re exploring the desert.
