Singapore is the most humid country in the world by dew point if you want the clearest single answer. It combines very high moisture levels with very little seasonal relief, which is why the air often feels sticky the moment you step outside. If you want a broader comparison, our guide to the most humid countries in the world covers the wider field too.
There is a bit of nuance. Qatar can hit even more extreme peaks during late summer, and Saudi Arabia holds the all-time dew point record at Dhahran. But for persistent, year-round mugginess, Singapore is the name that comes up again and again.
If you are trying to work out where humidity is worst, the key is to look past the percentage on a weather app. Dew point is the metric that best matches how oppressive the air feels, especially in tropical cities such as Singapore, Kuala Lumpur, Jakarta, Palembang, and Manaus.
What Counts As “Most Humid”?
Humidity gets measured in a few different ways, and that is where a lot of list articles go sideways. Relative humidity is temperature-dependent, so it can show 100% on a cool morning without feeling especially miserable. Dew point is much more useful for comparing one place with another.
Dew point measures how much moisture is actually in the air. The higher it gets, the harder it is for sweat to evaporate, which is why a hot day with a high dew point feels far more draining than a dry one. As a rough comfort guide, a dew point above 70°F feels uncomfortable to many people. Above 80°F feels oppressive.
For background on how surface water vapour and climatological normals are tracked, the World Meteorological Organization’s surface water vapour overview and WMO climatological normals guidance are useful references. For city-level climate patterns, many readers also compare station summaries from WeatherSpark.
Quick Answer: The World’s Most Humid Countries
This list blends high dew point patterns with the countries that repeatedly show up in humid-climate rankings and city records. It is best read as a practical guide to places where the air often feels heavy, not as a perfect one-to-twenty scientific league table.

|---|---|---|
| Singapore | Singapore | Most consistent year-round humidity, with dew points around 81 to 84°F through the year and afternoon relative humidity commonly staying above 70% |
| Qatar | Pearl-Qatar | Extreme seasonal peaks, reaching about 86°F in September when Gulf moisture piles in |
| Indonesia | Palembang, Jakarta | Palembang sits around 82 to 84°F year-round; Jakarta is regularly very muggy, especially in the wet season |

Which Country Is the Most Humid in the World?
Singapore is the strongest all-around answer. It sits almost on the equator, has a tropical rainforest climate, and does not get a real dry season that would give you a proper break. In practice, that means the city-state stays muggy month after month.
The numbers behind that reputation are pretty blunt. Singapore’s dew points sit in roughly the 81 to 84°F range year-round, with an average maximum around 83.8°F in April and still about 81.9°F in August. Daily temperatures in Singapore also tend to run around 31 to 33°C most afternoons, so the air rarely gets much help from a cooler spell.
If your personal definition of worst humidity is the highest spike ever felt by humans in a built-up place, then Qatar enters the chat. Pearl-Qatar has been cited for dew points around 86°F in September, and the wider Persian Gulf is famous for short periods of brutal, sauna-like air.
For the single highest dew point ever recorded, Dhahran in Saudi Arabia reached 95°F in 2003. That is an atmospheric outlier, not a year-round norm, but it belongs in the conversation whenever people ask about the most humid place on Earth.
The Muggiest Countries and Cities in Real Life
Singapore
Singapore is the benchmark for nonstop humidity. You can plan around rain showers, but not around the moisture in the air. If you are walking in Marina Bay, Chinatown, or around Orchard Road, the feeling is usually the same: a few minutes outdoors and your shirt starts negotiating terms.
That consistency is what puts Singapore ahead of many rivals. Plenty of places get very humid for part of the year. Singapore stays humid almost all the time. Afternoon temperatures were sitting around the low 30s°C in recent live readings (as of July 2026), which is exactly the sort of weather that makes short, air-conditioned breaks feel less like luxury and more like planning.
Qatar
Qatar is a different kind of humid. For much of the year, it is known more for heat and dryness, but along the coast and around Pearl-Qatar, late summer can produce some of the highest dew points on the planet.
July to October is the rough window, with September standing out for peak discomfort. Overnight lows in Doha can stay around 30°C or higher in late summer, so even evening walks may feel like somebody left the steam room door open.
Indonesia
Palembang is one of the strongest city-level cases anywhere, with dew points around 82 to 84°F through the year. That is elite-level stickiness. Jakarta is also repeatedly cited as a very humid city, with many days pushing relative humidity well above 80%.
Indonesia’s geography does a lot of the work here. Thousands of islands, warm seas, tropical rainfall, and equatorial heat all keep moisture hanging in the air. If you are comparing equatorial climates, it belongs in the same conversation as countries shaped by very different coastlines, because here the surrounding water is a major part of the problem.
Malaysia
Kuala Lumpur is another city that never really lets you forget where you are. April dew points around 83.3°F put it firmly in the same oppressive club as Singapore and parts of Indonesia.
The difference is not that Kuala Lumpur is comfortable. It is that Singapore is even more relentlessly consistent. This is a game of unpleasantly small margins. In Kuala Lumpur, frequent late-day storms can break the heat a little, but they usually leave the air feeling even thicker afterwards.
Brazil
Manaus, deep in the Amazon, is humid in a way that feels almost biological. October dew points around 83.7°F show just how moisture-heavy the central Amazon atmosphere can get.
If you have ever stepped off a plane into Manaus, you know the sensation. The air does not just feel warm. It feels occupied. Daytime temperatures commonly climb above 31°C, and the combination of rainforest moisture and urban heat means even short walks can feel longer than they are.
Other Very Humid Countries That Belong On the List
After the headline names, there is a larger group of countries that regularly appear in humid-climate comparisons or have major cities known for sticky conditions.
- Papua New Guinea is often cited with average relative humidity around 80%, especially in its coastal lowlands.
- Brunei has a classic equatorial climate with heavy moisture and little relief.
- Liberia sits on the humid West African coast and stays muggy for long stretches.
- Myanmar, especially around Sittwe, gets persistent moisture from the Bay of Bengal.
- Thailand and Vietnam combine tropical heat with long monsoon seasons, so cities such as Bangkok and Ho Chi Minh City can feel extremely sticky.
- The Philippines, especially Manila, deals with both monsoon humidity and typhoon-season moisture.
- The Maldives has warm, ocean-driven humidity all year.
- Colombia has very humid tropical lowlands, especially outside the cooler Andean zones.
- Nigeria, particularly Lagos and the Niger Delta, gets heavy coastal humidity.
- Costa Rica and Trinidad and Tobago are both strong examples of humid tropical air outside higher elevations.
These places are not interchangeable. Some are humid because of equatorial rainforest, some because of warm enclosed seas, and some because monsoon systems keep moisture levels high for months at a time. That is part of why two countries can feel equally sticky for totally different reasons.
Dew Point Vs. Relative Humidity
If you only remember one thing, make it this: a high relative humidity percentage does not always mean the air will feel worst. Dew point is usually the better guide to actual discomfort.
Cold air cannot hold much moisture, so 100% relative humidity on a cool morning can feel fine. Hot tropical air can feel awful even at a lower percentage because it is carrying far more water vapour. That is why weather apps can mislead people who are trying to compare countries.
For practical trip planning, watch the dew point if the data is available. Above 70°F gets uncomfortable. Above 75°F feels very muggy. Above 80°F is oppressive. If your weather app only shows humidity percentage, check the “feels like” temperature as a rough backup, though it is still less precise.
What Is the Most Humid Place on Earth?
That depends on whether you mean the most consistently humid place or the highest humidity ever recorded.
- Most consistently humid country: Singapore
- Most extreme seasonal urban humidity: parts of Qatar, especially around Pearl-Qatar
- Highest recorded dew point: Dhahran, Saudi Arabia, at 95°F in 2003
- Other extreme humidity zones: the Persian Gulf coast and parts of the Red Sea coast, including Eritrea
That is why different answers float around online. They are often talking about different definitions of humid. Some lists also lean on annual relative humidity averages, which can elevate cloudy or rainy places that do not necessarily feel as punishing as a tropical city with a brutal dew point.
How To Travel in Extremely Humid Countries Without Melting
If you are headed to one of these places, the good news is that people live, work, and go about daily life in them just fine. The less good news is that your usual cool-weather dignity may leave first.
- Plan outdoor walks early or late. Midday heat plus high dew point is the roughest combination.
- Use indoor breaks strategically. In cities like Singapore, Kuala Lumpur, and Manila, malls, metro stations, and museums can be part climate shelter, part sightseeing stop.
- Choose lighter fabrics. Cotton is comfortable for short wear, but many people prefer quick-dry clothing in tropical cities.
- Hydrate more than you think you need. Humid heat can feel less dramatic than desert heat, but it still drains you.
- Accept that laundry dries slower. In very humid climates, this is not user error. It is physics being annoying.
If you already plan trips around weather windows, you might also like comparing this with destination-specific guides such as St Lucia weather in April or more hiking-focused reads like Ben Ledi weather in August. Same planning habit, very different kind of sweating.
FAQ: The World’s Most Humid Countries
Which country has the highest humidity in the world?
Singapore is the best single answer when humidity is measured by dew point and judged across the whole year. It stays oppressively humid with very little seasonal relief.
What is the most humid place on Earth?
Dhahran in Saudi Arabia holds the highest recorded dew point at 95°F in 2003. For places that are humid most of the time, Singapore and parts of Indonesia are stronger examples.
Is Qatar more humid than Singapore?
Qatar can reach higher short-term peaks, especially around the Persian Gulf in late summer. Singapore is more consistently humid across the entire year.
Why use dew point instead of relative humidity?
Dew point is more comparable from place to place because it measures the actual moisture in the air. Relative humidity changes with temperature and can be misleading on its own.
Which cities feel the most humid?
Singapore, Kuala Lumpur, Palembang, Jakarta, and Manaus are among the standout examples based on the climate patterns and figures discussed here.
Final Word
If your question is simple, the answer can be simple too: Singapore is the world’s most humid country if you care about the place that feels sticky most consistently. If you care about brief but monstrous peaks, look to Qatar and the Persian Gulf. If you care about the all-time atmospheric record, that goes to Dhahran in Saudi Arabia.
And if you are planning a trip to any of them, pack light, walk slower, and make peace with the fact that some climates do not do crisp and refreshing. They do glossy.
