When you spend summer in Lome, you step into a season defined by warmth, heavy rains, and shifting skies. You’ll find hot days averaging around 28°C to 32°C (82°F to 90°F), and frequent showers shape the rhythm of daily life.
The air feels sticky with humidity. While rain cools things off, it also brings cloudy skies and less sunshine.
The city’s spot on the coast keeps things more moderate than inland, but summer is still the wettest time of year. Rainfall peaks in June, then slowly eases through July and August. The ocean stays inviting, with water temperatures hovering in the mid-20s °C.
If you’re planning outdoor activities, timing matters, especially if you want to mix sightseeing and beach time.
It really helps to know what to expect. From average temperatures and rainfall to sea conditions and daylight hours, every bit of Lome’s summer climate shapes your experience.
Overview of Lome’s Summer Climate
Lome’s summer months bring frequent rainfall, high humidity, and slightly cooler daytime highs than the rest of the year. The city’s coastal location and tropical setting create wetter and cloudier summers than other seasons.
Geographical Factors Influencing Weather
Lome sits on the Gulf of Guinea in southern Togo, just a few meters above sea level. This spot puts you right in the path of moist Atlantic air, which drives much of the summer rain.
Since Lome is near the equator, daylight doesn’t really change much—about 12 hours, give or take. The ocean nearby keeps temperatures from swinging wildly.
Summer temperatures usually range from 27°C to 29°C (81°F to 84°F). Nights stay warm, often above 23°C (73°F).
The ocean cools a bit in August, dipping to around 24°C (75°F), which is as cool as it gets all year.
Rainfall tops out in June, often over 130 mm (5 in). By July and August, it drops off but sticks around, with cloudy skies cutting down on sunshine.
Tropical Climate Characteristics
Lome has a tropical wet and dry climate (Aw) under the Köppen system. In summer, the “wet” phase takes over, bringing heavy showers and high humidity.
Humidity stays above 75%, so the air feels warmer than the thermometer says.
Rain falls in quick, intense bursts, not all day long. You might get several rainy days in a row, but you’ll also see lighter clouds in between.
Winds shift in summer, with moist southwesterlies blowing in from the ocean. These winds spark thunderstorms and ramp up the cloud cover.
Sunshine hours drop to just 2 or 3 per day in June, then climb a bit in August.
Daytime highs stay steady, rarely dipping below 27°C (81°F). The mix of heat, humidity, and frequent rain really defines Lome’s summer and affects how you plan your time outside.
Average Summer Temperatures
You’ll notice steady warmth all summer in Lome, with only small changes month to month. Daytime highs and nighttime lows stay close together, but rain and clouds can make it feel hotter or cooler.
Monthly Daytime and Nighttime Temperature Ranges
Daytime temperatures during summer usually land between 28°C (82°F) and 31°C (88°F). There’s a slight drop from June to August, especially compared to the hotter months earlier in the year.
Nights stay warm, with lows often between 23°C (73°F) and 25°C (77°F).
Humidity makes the air feel heavier, especially in June when it peaks. Even at night, the warmth and moisture can feel a bit much.
Since temperatures don’t swing much from day to night, you won’t get much relief after sunset. If you want to be outside, early mornings are your best bet for comfort.
Hottest and Coolest Summer Months
June usually brings the warmest summer weather, with average highs near 30°C (86°F). The mix of heat and frequent rain makes it feel even more humid.
By July and August, highs dip a bit to around 28–29°C (82–84°F). Nights cool off too, dropping closer to 23°C (73°F).
These months feel more comfortable, especially when cloud cover keeps the sun from beating down.
Even though the changes seem small, travelers often pick up on the difference. If you’re not a fan of heat, July and August are easier for sightseeing than June.
Temperature Variations Throughout the Day
The hottest part of the day hits in the early to mid-afternoon, when the sun is at its strongest. Temperatures climb quickly after late morning, especially if there aren’t many clouds.
By evening, things cool off a little, but it’s still warm. Nighttime lows stick in the mid-20s °C (mid-70s °F), so the heat lingers after dark.
Morning hours are the most comfortable for being outside. Lower temperatures and light breezes make this the best time for walks, markets, or a trip to the beach.
Rainfall and Humidity Patterns
During summer in Lome, you deal with frequent rainfall, high humidity, and changes in cloud cover that affect how comfortable each day feels. The wet season really sets the tone, shaping how you plan your activities and how the city feels.
Monthly Rainfall Totals
Rainfall peaks in June, making it the wettest month of the year. Expect around 138 mm (5.4 in) of rain, often spread over more than 25 days.
July brings less rain, about 95 mm (3.7 in), and August drops to 52 mm (2.0 in).
This steady decline continues into September, when totals rise again to about 103 mm (4.1 in). Rain doesn’t just stop; it fades slowly. Instead of heavy downpours all at once, you’ll often get lighter showers stretched over many days.
| Month | Rainfall (mm) | Rainy Days |
|---|---|---|
| June | 138 | 26–27 |
| July | 95 | 20–22 |
| August | 52 | 15–17 |
| September | 103 | 23–25 |
You’ll definitely want to keep rain gear handy through most of the summer.
Rainy and Drier Periods
Lome’s summer doesn’t bring a single block of rain. Instead, you see a peak in June, a dip in July and August, and then a bounce back in September.
June can feel the trickiest for outdoor plans, with lots of cloud cover and not much sun.
By July and August, the rain lets up, giving you a few more dry hours during the day.
September brings back the rain, with wet days on the rise again. If you want a better shot at dry weather, July and August offer the best balance.
Average Humidity Levels
Humidity in Lome stays high all summer, often above 80%. The air feels heavy, and afternoons can get uncomfortable.
In June, humidity climbs with the rains, and by August it’s close to 85%, one of the highest averages of the year.
High humidity and warm temperatures can make even light activity feel tiring.
Unlike the rain, humidity doesn’t drop much between months. Even in July, when rain is less, the air stays moist.
Expect sticky conditions day and night, with little help from coastal breezes.
To stay comfortable, plan on taking shaded breaks, wear light clothes, and drink plenty of water.
Sea Temperature During Summer
Sea temperatures in Lome change more than air temperatures during summer. The water cools off a bit in mid-summer, which can affect how nice a swim feels.
Monthly Sea Temperature Averages
From June to August, the sea along Lome’s coast goes from warm to a bit cooler than the rest of the year.
In June, water temps hit around 26–27°C (79–81°F), which feels great for most swimmers.
By July, the sea cools to about 25–26°C (77–79°F). On humid days, this feels pretty refreshing.
August is the coolest, with sea temperatures dropping to 24–25°C (75–77°F). It’s still fine for swimming, but you’ll notice the difference compared to spring or autumn.
| Month | Average °C | Average °F |
|---|---|---|
| June | 26–27 | 79–81 |
| July | 25–26 | 77–79 |
| August | 24–25 | 75–77 |
August stands out as the coolest month for the sea, but the pattern stays pretty consistent year to year.
Best Months for Swimming and Water Activities
If you want warmer water, June is your best bet for swimming. The sea stays close to 27°C (81°F), perfect for long swims or snorkeling without getting chilled.
July is still good, though the water’s a bit cooler. Most visitors find it pleasant, especially with warm air temperatures in the low 80s°F.
August is the least ideal for long swims. With sea temps at 24–25°C (75–77°F), you might feel the chill sooner, especially if you stay in the water a while.
For casual beachgoers, all three months work, but if you want the warmest water, June is the sweet spot.
Wind Speed and Air Movement
Winds in Lome stay moderate through summer, shaped by coastal breezes and inland patterns. You’ll get steady movement of air that helps cut the heat, though some days still feel humid and heavy, depending on rain and cloud cover.
Monthly Wind Speed Averages
During summer, average wind speeds in Lome usually range between 7 to 12 km/h (4 to 7 mph). These numbers come from long-term records at Lomé–Tokoin Airport, which is right near the coast.
Winds are light to moderate, not often gusty. June and July are a bit calmer because of frequent rain and clouds.
By August, wind speeds pick up as drier air mixes in with the coastal flow.
| Month | Avg Wind Speed | Notes |
|---|---|---|
| June | 7–9 km/h | Rainy, calmer air |
| July | 8–10 km/h | Frequent showers |
| August | 10–12 km/h | Breezier, less rain |
This steady, manageable wind makes it easy to enjoy outdoor activities. Walking along the beach or light sailing usually go off without a hitch.
Seasonal Breezes and Harmattan Influence
Coastal breezes play a big role in keeping Lome’s summer heat from feeling overwhelming. Air moves inland from the Gulf of Guinea, especially in the afternoons, giving you a bit of relief from all that humidity.
The Harmattan—a dry, dusty wind from the Sahara—doesn’t really show up in summer. It’s more of a winter thing. Still, if it arrives early, you might notice drier air and a faint haze.
Summer winds feel heavier and more humid compared to the crisp, dry air of Harmattan season. If you’re sensitive to air quality or planning a lot of time outside, this difference matters. Those coastal breezes are your best friend in these months.
Sunshine and Daylight Hours
You get steady daylight in Lome during summer, but the amount of actual sunshine varies a lot. Cloud cover and seasonal rain cut down on bright sun, even though the days stay right around 12 hours long.
Average Daily Sunshine Hours
In summer, Lomé actually gets fewer hours of direct sunshine than you might expect. June brings about 4 hours and 46 minutes of sunshine each day.
July gets even cloudier, dropping to around 4 hours and 5 minutes of sun. August brightens up a bit with roughly 4 hours and 29 minutes daily.
So, in July and August, you only see sunshine for about a third of the daylight hours. Most of the time, clouds, haze, or rain fill the sky instead.
This weather lines up with the region’s rainy season, which really hits its stride in June and July.
If you’re hoping for outdoor plans, mornings usually give you steadier brightness before the clouds roll in.
Travelers will probably notice humid conditions and limited sun, which definitely shapes sightseeing and beach days.
Length of Days in Summer
Daylight hours in Lomé don’t change much, since the city sits so close to the equator.
In June, you get about 12 hours and 28 minutes of daylight. July is almost the same at 12 hours and 26 minutes, and August is just a bit shorter with 12 hours and 18 minutes.
The difference from one month to the next is barely 15 minutes. The longest day is only about 42 minutes longer than the shortest.
You can count on sunrise near 6:00 AM and sunset around 6:30 PM all summer.
Tips for Visiting Lome in Summer
Summer in Lome means high humidity, lots of rain showers, and daytime highs that feel a little cooler than in other months.
You’ll want to prepare for wet conditions, but the warm weather still makes outdoor adventures doable if you plan ahead.
What to Pack for the Weather
Definitely pack lightweight, breathable clothing like cotton or linen. These keep you comfortable in humid air and dry quickly after a surprise rainstorm.
A compact umbrella or light rain jacket comes in handy, since June and July often bring showers out of nowhere.
Footwear can make a big difference. Waterproof sandals or quick-dry shoes beat heavy sneakers, which just soak up water and stay wet.
If you’re walking around markets or tackling muddy roads, you’ll want shoes with good grip to avoid slipping.
Don’t skip sun protection. Even with all those clouds, UV levels stay high. Bring sunscreen, sunglasses, and a hat.
A small backpack with a waterproof cover helps keep your stuff dry if the rain catches you off guard.
How Weather Impacts Outdoor Activities
June usually brings the heaviest rainfall, and you’ll notice plenty of cloudy days. If you’re planning to sightsee, it’s smart to have indoor options like museums or markets in your back pocket.
Storms can cause streets to flood briefly, which really slows down travel.
You can still hit the beach, though sometimes the sea feels rougher and the water gets pretty chilly by August. Swimming stays safe in designated spots, but always check local conditions first, just in case.
Cultural events and city tours keep rolling through the season. You’ll just need to plan around the weather, which can be a bit of a gamble.
Early mornings usually offer drier, clearer skies, so that’s your best bet for a walking tour or snapping photos. If you stay flexible, you can still make the most of the city even when it rains.
