Summer in Monrovia feels pretty different from what you might expect in a typical tropical city. You’ll run into warm temperatures between 26°C and 29°C (79°F to 84°F), mixed with heavy rainfall that really marks the rainy season.
The air stays warm, but frequent showers and thick clouds really shape your day-to-day experience. It’s not just a passing drizzle either—summer in Monrovia means you’ll need to stay flexible with your plans.
From June through August, it rains nearly every day, usually in short, powerful bursts. Skies tend to stay overcast, and you might only catch a few glimpses of sunshine, so outdoor plans often depend on luck.
Humidity lingers at high levels. Steady winds from the Atlantic sometimes offer a little relief, though it’s not always enough to shake off the heat.
This blend of warmth, rain, and shifting skies gives Monrovia a unique summer rhythm. If you want to explore the coast or dive into local culture, it’s good to know what you’re in for ahead of time.
Monrovia’s Summer Climate Overview
Summer in Monrovia falls right in the peak of the rainy season, shaped by its tropical monsoon climate. You’ll notice high humidity, heavy rainfall, and slightly cooler temperatures than during the dry months.
Tropical Monsoon Climate Characteristics
Monrovia sits in a tropical monsoon climate (Am) zone. You’ll feel warm temperatures all year, with only small changes from season to season.
In summer, average highs settle near 26–27°C (79–81°F). Lows hang close to 24–25°C (75–77°F).
Humidity spikes during these months, often hitting 80–86%. Warm air and high moisture mean lots of cloud cover, so you get just 3–5 hours of sunshine per day.
Rain falls hard and often. June usually brings the most rain, with over 300 mm (12 in) in a single month. July and August stay very wet too, each bringing 230–260 mm (9–10 in) or more.
Winds pick up a bit, averaging 8–15 km/h (5–9 mph). They help a little with the heat, but don’t really dry things out. So, summer in Monrovia is less about blazing heat and more about constant moisture and cloudy, hazy days.
Seasonal Weather Patterns
From June through August, you’ll face near-daily rain showers. It’s normal to see 25–30 wet days per month, so outdoor activities need some flexibility.
The heaviest storms usually hit in the afternoon or evening. These storms can be fierce and short, then fade to lighter rain or just cloudy skies.
Even when it stops raining, the ground stays wet and humidity refuses to drop. Temperature changes are pretty minor. Monrovia doesn’t get big seasonal swings.
Summer brings a slight cooling compared to the dry season, with highs dropping a bit from earlier months. Rain and clouds mean less sunshine. August is often the cloudiest, with daylight lasting 12 hours but sunshine averaging under 4 hours daily.
If you’re traveling now, expect frequent rain, slippery roads, and slower trips. On the bright side, the city turns lush and the air feels a bit cooler than in the dry season.
Average Summer Temperatures in Monrovia
Summer in Monrovia stays warm and sticky, with only small changes between day and night. You’ll notice steady heat, and evenings don’t cool down much.
Daytime Highs and Nighttime Lows
During summer, the average daytime high sits between 80°F and 85°F (27°C to 29°C). Even at the hottest part of the day, it rarely climbs above 88°F, so you won’t face extreme heat like in some inland places.
At night, temperatures settle around 75°F (24°C). It almost never drops below 73°F, so evenings remain warm and humid.
Here’s a quick breakdown:
| Time of Day | Average Temperature | Range |
|---|---|---|
| Daytime High | 80–85°F (27–29°C) | Rarely above 88°F |
| Nighttime Low | ~75°F (24°C) | Rarely below 73°F |
Packing is simple—you won’t need heavy layers, even late at night.
Temperature Variability During Summer
Unlike places with big seasonal swings, Monrovia’s summer climate barely changes. From June to August, daily highs slowly drop by about 4°F, starting near 85°F in June and landing around 80°F by mid-August.
Nighttime lows barely budge, hovering at 75°F. Week to week, you won’t notice much difference, except maybe slightly cooler afternoons later in summer.
Monrovia’s equatorial location and the Atlantic keep things steady. Rain and clouds may shift, but the temperature stays predictable.
For travelers, it’s nice to know you’ll get similar warmth throughout the season. The small gap between day and night temps gives the city a uniform feel—the air stays warm around the clock, adding to that humid, tropical vibe.
Rainfall and Rainy Days in Summer
You’ll find wet conditions in Monrovia all summer. Rainfall peaks, and the sheer number of rainy days makes outdoor planning a real challenge.
Monthly Average Rainfall
Rainfall in Monrovia jumps from June through August. June usually brings the heaviest downpours, with totals that can top 600 mm.
July stays wet, sometimes dipping a little, but by August, rainfall usually climbs again—matching or beating June’s numbers.
For context, Monrovia’s summer rainfall dwarfs what many coastal cities get in a whole year. New York City, for example, averages about 1,276 mm annually, but Monrovia can blow past 1,800 mm in just three months.
| Month | Average Rainfall (mm) |
|---|---|
| June | ~650–670 mm |
| July | ~500–600 mm |
| August | ~650–700 mm |
That’s why Monrovia ranks among the world’s wettest capitals during summer.
Frequency and Duration of Rainy Days
Rain isn’t just heavy—it’s frequent. You’ll see rain on 25 to 28 days each month in summer, so most days bring at least a shower or two.
Showers can be quick but intense, and sometimes they hit more than once a day. Thick clouds cut down sunshine, leaving only brief breaks of blue sky.
In September, rainfall peaks at over 25 rainy days, but June through August already get close. Because of all this, you’ll need to hunt for dry windows.
Outdoor plans work best early in the morning, since heavy showers often build up by afternoon. This pattern fits Monrovia’s tropical monsoon climate and really shapes daily life in summer.
Humidity and Wind Conditions
During summer in Monrovia, you’ll notice high humidity and steady winds. The air feels heavy with moisture, but breezes from the Atlantic give a bit of relief.
Typical Relative Humidity Levels
Humidity in Monrovia during summer stays stubbornly high. Most days, relative humidity hovers between 80% and 86%.
This much moisture makes the heat feel more intense, even when the thermometer only shows upper 70s or low 80s °F. June through August combine constant rain with little sunshine.
Clouds keep the air from drying out, so you never really get a “dry heat.” The air feels sticky, and even your clothes might take a while to dry.
If you’re planning to be outside, brace yourself for the oppressive humidity. Light clothing, plenty of water, and shady breaks help a lot.
Evenings might feel a bit more comfortable, but humidity rarely dips below 75%, even late at night.
Prevailing Wind Speeds and Gusts
Winds in Monrovia during summer usually blow in from the southwest, thanks to the Atlantic. Average wind speeds range from 8 km/h (5 mph) up to about 15 km/h (9 mph).
These aren’t strong winds, but the steady breeze does make the muggy air a little easier to handle. From May to September, gusts pick up during heavy rainstorms, though they rarely get strong enough to cause problems.
You’ll notice quick bursts of stronger wind that cool things off for a moment. If you’re near the coast, winds can feel stronger, especially late in the day.
So, expect a damp but breezy feel—never quite dry, but not totally still either.
Cloud Cover and Sunshine Hours
Monrovia’s summer skies stay mostly cloudy, with only a few breaks for sun. Sunshine is around, but thick cloud cover and frequent rain keep it limited.
Seasonal Cloudiness Trends
Cloud cover in Monrovia remains high all summer. You’ll see overcast or mostly cloudy skies more than two-thirds of the time.
At the start of June, there’s about a 76% chance of heavy cloud cover, and by late August it drops just a bit to around 69%. The clearest day usually falls in early July, when skies are clear, mostly clear, or partly cloudy about 37% of the time.
Still, cloudiness dominates the scene. Compared to the drier months, summer barely gives you any clear days.
This links directly to the rainy season—moisture and storms keep the skies gray and visibility low. If you want to be outside, plan for limited sunshine.
Average Daily Sunshine During Summer
Direct sunshine in Monrovia is hard to come by in summer. On average, you get just 2 to 4 hours of bright sun per day. August is the gloomiest, dropping to about 2.7 hours.
For comparison, the dry season brings over 6 to 7 hours of sunshine daily. That’s a big difference and really shows how the rainy season cuts down on sunlight.
Daylight still lasts about 12 hours, but most of it comes through clouds. You’ll experience bright, diffused light instead of direct sunbeams.
If you’re traveling, expect humid, shaded days rather than sunny, dry ones.

Summer in Monrovia, Liberia means heavy rain, high humidity, and lots of cloud cover. You’ll find warm temperatures throughout, but the wet weather will shape your plans and what to expect during your stay.
Best Practices for Outdoor Activities
Try to plan your outdoor time with the rain in mind. Since downpours usually hit in the afternoon or evening, early mornings tend to give you the best chance to explore without getting soaked.
Pack a light rain jacket and some waterproof footwear—streets can flood fast when the rain really comes down.
Humidity often sits above 80%, so take it easy when you’re walking or sightseeing. Remember to drink lots of water. Take short breaks in shaded or air‑conditioned spots if you can.
Thinking about visiting beaches near Monrovia, like Kendeja or Silver Beach? It’s smart to check beach conditions first. Rough seas and strong currents pop up a lot during rainy season.
If the weather turns stormy, maybe swap beach plans for indoor spots like museums or local markets.
A small umbrella, insect repellent, and some quick‑dry clothing can make your days way more comfortable.
If you’re heading out of the city for a while, just know that muddy roads might slow you down.
What to Expect When Visiting
You can expect daily highs around 26–28°C (79–82°F). At night, the temperature usually drops to about 24–25°C (75–77°F).
The air always feels a bit heavier because of the humidity, so it’s probably going to feel warmer than the numbers suggest.
It rains a lot here. June often brings more than 300 mm (12 in) of rain. July and August don’t hold back either, with plenty of heavy showers.
Cloudy skies are pretty common, cutting down sunshine to maybe 4–6 hours a day.
The air stays fresh, but the dampness can get uncomfortable. You might notice your clothes drying slowly, and sometimes there’s a musty smell in certain places you stay.
Storms can knock out the electricity, so it’s smart to carry a backup power bank just in case. If you’re flying regionally or planning a road trip, keep in mind that travel delays can pop up.
Even with all that, the city feels energetic. Markets, food stalls, and cultural events just keep going, rain or shine.
