Tips How To Reduce Humidity in Singapore

December 11, 2023

Singapore has a tropical climate, characterized by high humidity throughout the year. The country experiences a relatively constant level of humidity due to its proximity to the equator and its geographical location surrounded by water bodies.

The average relative humidity in Singapore typically ranges from around 70% to 90%. This means that the air is often saturated with moisture, making it feel humid and sticky. The highest average humidity levels are usually observed during the rainy season, which occurs from November to January, and the lowest levels are experienced during the drier months of May to July.

Definition of Humidity

Humidity refers to the amount of water vapour or moisture buildup in the air. It is a measure of the water content in the atmosphere and is an important factor in understanding and describing atmospheric conditions.

Humidity has a significant impact on our comfort and well-being. High humidity levels can make the air feel hot and sticky, while low humidity levels can lead to dry skin, respiratory discomfort, and static electricity. It also plays a crucial role in various weather phenomena, such as the formation of clouds, precipitation, and the overall climate of a region.

Causes of Humidity Issues in Singapore

The high humidity in Singapore is primarily caused by its geographical location and climate factors. Here are a few hours of the main causes of humidity in Singapore:

1. Proximity to the Equator

Singapore is located just 1.5 degrees north of the equator, which means it receives direct sunlight year-round. The strong and direct sunlight leads to high evaporation rates, increasing the moisture content in the air.

2. Maritime Tropical Climate

Singapore has a maritime tropical climate, characterized by high temperatures and high humidity. The country is surrounded by water bodies, including the Singapore Strait and the South China Sea. The warm waters of these seas contribute to the moisture in the air, leading to high humidity levels.

3. Southeast Monsoon Winds

Singapore experiences two monsoon seasons—the northeast monsoon (December to March) and the southwest monsoon (June to September). During the southwest monsoon, winds blow from the southeast, bringing moisture from the sea and increasing humidity levels.

4. Rainfall

Singapore has a relatively high annual rainfall, with frequent showers and thunderstorms throughout the year. The rainfall contributes to the moisture in the air, further raising the humidity levels.

5. Lack of Seasonal Variations

Unlike some regions that experience distinct seasons, Singapore has a relatively cool and consistent climate with little temperature variation throughout the year. The absence of significant seasonal changes prevents the air from drying out, maintaining consistently and experiencing high humidity levels.

6. Urbanization and Greenery

The rapid urbanization and extensive greenery in Singapore contribute to local microclimates. Urban areas with buildings and concrete surfaces can trap heat and moisture, leading to higher humidity levels. However, the presence of parks, gardens, and green spaces helps regulate the humidity level to some extent by providing natural ventilation and moisture absorption from fresh air.

Impact of High/Low Humidity Levels on your residence.

High and low humidity levels can both have significant effects on your home and its occupants. Here's how high and low humidity can impact various aspects of your home:

High Humidity Effects:

1. Discomfort: High humidity can make every room in your home feel hot, sticky, and uncomfortable. It can make it difficult for sweat to evaporate from your skin, leading to a feeling of stickiness and reduced comfort.

2. Respiratory Problems: High humidity levels can worsen respiratory conditions such as asthma, allergies, and sinusitis for some individuals. The moist air can make it difficult to breathe, trigger allergic reactions, and promote the growth of mould and dust mites, which can exacerbate respiratory symptoms.

3. Mold and Mildew Growth: Excessive moisture in the air can promote the growth of mold and mildew. These can thrive on surfaces like walls, ceilings, and bathroom fixtures, leading to unsightly stains, unpleasant odours, and potential health risks.

4. Structural Damage: Prolonged exposure to high humidity levels can cause structural damage to your home. Moisture can seep into walls, ceilings, and wooden structures, leading to rot, warping, and degradation over time. Besides, high humidity levels can damage sensitive electronic equipment.

5. Pest Infestations: Certain pests, such as dust mites, cockroaches, and silverfish, thrive in humid environments. High humidity and low light plants can increase the likelihood of pest infestations and contribute to their growth and reproduction.

6. Condensation: When warm air with high humidity comes into contact with cooler surfaces, condensation can occur. This can lead to water droplets forming on windows, walls, and other surfaces, potentially causing damage to paint, wallpaper, and wooden elements.

Low Humidity Effects:

1. Dry Skin and Respiratory Issues: Low humidity can cause dryness of the skin, lips, and eyes. It can also lead to respiratory discomfort, exacerbating conditions like allergies, asthma, and sinus problems.

2. Static Electricity: Dry air tends to generate static electricity, resulting in unpleasant shocks when touching metal objects or other people. It can also cause problems with electronics and increase the accumulation of dust and airborne particles.

3. Cracking and Warping: Insufficient moisture more oxygen levels in the air can cause certain materials, such as wood, to lose moisture and shrink. This can result in cracking, warping, and damage to wooden furniture, flooring, and musical instruments.

4. Increased Energy Consumption: In cold weather, low humidity can make the air feel colder than it is. As a result, you may need to use more heating to maintain a comfortable temperature, leading to higher energy bills.

5. Dry Skin and Irritation: Low humidity can cause dryness of the skin, lips, and eyes. It can lead to itching, flaking, and irritation of the skin, exacerbating conditions like eczema and dermatitis.

Other Factors Causing Humidity, besides the weather

1. Indoor Activities

Everyday activities such as cooking, showering, and doing laundry generate moisture in the air. The water vapour released during these activities can increase humidity levels indoors if proper ventilation is lacking.

2. Poor Ventilation

Inadequate ventilation can trap moisture inside your home, leading to increased indoor humidity levels. Without proper air circulation, moisture from activities, as well as from sources like plants and pets, can accumulate and raise indoor humidity levels.

3. Water Intrusion

Water leaks from plumbing issues, roof leaks, or foundation problems can introduce excess moisture levels into your home. If left unaddressed, these issues can contribute to elevated humidity levels and potential mold growth.

Ways to reduce humidity in Singapore

1. Use Air Conditioning Units

Most air conditioning units help to cool the air and remove moisture. Set your air conditioner to an optimal temperature and ensure it is in good working condition. Use the "dehumidify" or "dry" air conditioning mode, if available, which specifically helps in reducing humidity.

2. Use Dehumidifiers

Dehumidifiers are appliances designed to absorb moisture from the air. Consider using a dehumidifier in areas with high humidity, such as basements, laundry rooms, or areas prone to dampness. Empty and clean the dehumidifier regularly to keep humidity problems and prevent mold growth. Aim for a ideal humidity level between 30% to 50%, adjusting your ventilation and dehumidification efforts accordingly.

3. Increase Ventilation

Good ventilation allows humid air to escape a room and fresh air to circulate. Open windows and doors when the outdoor humidity levels are lower, such as in the early morning or evening. Use exhaust fans in bathrooms, kitchens, and laundry areas to remove excessive moisture from these spaces.

4. Maintain Indoor Plants

Some plants release moisture through transpiration, which can contribute to indoor humidity and act as natural air purifiers. Limit the number of indoor plants or choose plants that have lower transpiration rates.

5. Insulation and sealing

Proper insulation and sealing of your home can help reduce humidity levels. Insulation helps to prevent heat transfer and moisture from the house to outside while sealing gaps and cracks in windows and doors minimizes the entry of humid air.
