Ever entered a room to see your windows covered in a foggy layer of moisture—even though it's scorching hot outside? That's condensation. And yes, it does occur in summer as well. Although we generally link it with cold winter mornings, summer condensation is more common than you would imagine.
If you're wondering how to reduce condensation on windows this summer, you're on the right place! Let's discuss what causes it, why it is more than just a nuisance, and what you can do to fix it—starting today.
Why Do Windows Fog Up in the Summer?
Here's the easy explanation: condensation occurs when hot, moist air meets a cold surface—such as your window glass. During summer, this commonly occurs due to:
- Excessive indoor humidity from showering, cooking, or drying clothes indoors.
- Air conditioning, which makes indoor air cooler and allows moisture to adhere to cooler surfaces.
- Poor airflow, which holds moisture in one area (such as near windows).
The outcome? Foggy windows that may seem harmless but could result in mold development, water damage, or warped window frames down the line.
How to Reduce Condensation on Windows This Summer
Good news: you can prevent summer window condensation with a few minor lifestyle tweaks and the proper moisture-absorbing tools. Here's where to begin:
1. Enhance Air Flow
Open your windows (when the outside air isn't too humid) or use fans to enable moisture to circulate and not accumulate.
- Use exhaust fans in kitchens and bathrooms
- Don't block vents or air returns
- Leave interior doors open for increased airflow
2. Use a Dehumidifier
Too much humidity is the number one cause of foggy windows. If you live in a humid neighborhood, a compact dehumidifier can keep the air moisture in check.
3. Place Moisture Absorber Bags or Boxes
This is one of the simplest, low-effort methods of reducing condensation. Moisture absorber bags and boxes quietly do their job in the background by drawing out excess moisture from the air—particularly in small or confined areas such as:
- Window sills
- Closets
- Bedrooms
- Bathrooms
Clevast's moisture absorber bags are ideal for putting near windows to prevent condensation from becoming an issue. They keep air at balanced humidity levels and have your space smelling wonderful—not damp.
4. Avoid Drying Clothes Indoors
It's easy when you're not up for going outside, but drying clothes indoors introduces so much excess moisture into the air. Instead:
- Have a clothes dryer with an actual vent
- Hang clothes outside whenever you can
- If drying indoors is not avoidable, have a window open or a fan operating
5. Check for Air Leaks
Sometimes, condensation is made worse by poor insulation or leaky window seals. Do a quick inspection:
- Check for drafts around windows
- See if the seals are cracked or broken
- Use weatherstripping or sealant to fix small gaps
6. Leave Blinds or Curtains Open During the Day
Allowing sunlight to enter your window glass will warm the glass, which will help to decrease the temperature gap between the inner and outer side of your windows—aka, less fog!
A Quick Recap: Summer Window Condensation Checklist
Following is an easy-to-use checklist for staying on top of things:
✅ Increase airflow with fans or open windows
✅ Operate a dehumidifier if the humidity is high
✅ Locate moisture absorber bags near the affected areas
✅ Do not dry clothes indoors
✅ Block out window drafts or gaps
✅ Bring in sunlight by leaving curtains open
