What Do Your Quad Cities Windows Need, Season by Season?
Plan your windows by season and by which side of the river you live on. The Mississippi runs east to west through the Quad Cities. So Iowa-side river rooms face south into the sun. Illinois-side river rooms face north. Winter calls for warmth and every bit of daylight. Summer calls for glare control. Fall calls for privacy once the leaves drop. Set up each room for its hardest season.
Why do the seasons hit Quad Cities windows so differently?
Because we get all four of them, and none of them go easy. The National Weather Service puts Moline's normal January temperature at 23.3 F. That's the day and night average. By July the normal climbs to 75.5 F. That's a swing of more than 50 degrees.
Your windows sit right in the middle of that swing. The same glass that lets in a welcome patch of sun in January can bake a room in July. A covering that's great in one season can be the wrong tool six months later.
So it helps to split a Quad Cities year into four parts. Each part gives your windows one main job:
- Winter: hold warmth in and let every bit of daylight through.
- Spring: start managing the stronger sun before the heat shows up.
- Summer: control glare and heat so rooms stay usable all afternoon.
- Fall: get privacy back as the trees thin out. Then get ready for cold.
Most homes don't need a different covering for every season. They need the right covering in each room. Pick it for the season that room struggles with most.
Which way do my river windows face, Iowa side or Illinois side?
This is a big part of what makes the Quad Cities different. For most of its length, the Mississippi runs north to south. Here it bends and runs east to west. The City of Rock Island puts it plainly. This is where "the river runs east and west."
That one fact splits the area in two:
- Iowa side (Bettendorf, Davenport): river views look south. That's where the sun spends the day. River rooms here get strong sun plus light bouncing off the water.
- Illinois side (Rock Island, Moline, East Moline): river views look north. North light is soft and steady. But it can feel dim in winter, and these rooms rarely get direct sun on the river side.
So two homes looking at the same river can need opposite things. A Bettendorf family room facing the water may need glare control most of the year. A Moline living room facing the water may need shades that clear the glass all the way. Otherwise the room can feel gray in January.
Upriver in LeClaire, the river turns again. It sits on the east side of town, so river rooms there face east. Not on the river at all? The same thinking still works. Open the compass app on your phone and stand at the window. Note which way it faces. That one note will guide most of your choices.
What do windows need in January cold and eagle season?
In January the job is simple. Keep the warm air in and let the light in.
It's also the coldest stretch of the year. KWQC looked at the 1991 to 2020 normals for Quad Cities International Airport. From about January 14 to 22, the normal high is just 31 F and the normal low is 14 F. After that, things start to warm up a degree at a time.
January is eagle season too. From January to March, bald eagles flock to the dams on the Mississippi to feed. That's according to the U.S. Army's guide to the Mississippi River Visitor Center. The center sits at Locks and Dam 15 on Rock Island Arsenal. The Corps of Engineers runs it, and visitors come each winter to see the eagles.
If you've stood by the river on a cold morning, you know the light off the water can be bright. It's bright even when the air is bitter. That same low winter sun reaches deep into south-facing rooms on the Iowa side.
Here's what helps at the window this time of year:
- Cellular shades. The honeycomb cells hold a layer of air between the room and the glass. Raise them on sunny days to soak up the light. Lower them at night to keep the heat in.
- Drapery over shades. Lined drapery over a shade adds one more layer on the coldest nights. It makes a chilly room feel warmer too.
- Coverings that clear the glass. For north-facing rooms on the Illinois side, pick shades that stack up small at the top. Then the whole window can let in daylight.
One habit makes a real difference. Open the south side of the house during the day. Close everything up at sunset. It costs nothing, and you'll feel it.
Why is February a good month to plan?
February is the slow month. The holidays are over and spring projects haven't started. You're spending a lot of time indoors looking at your windows. It's a good time to notice what bugs you.
It's also home show season. The Quad Cities Builders & Remodelers Association (QCBR) held its 2026 Home Show February 13 to 15 at the Bend XPO in East Moline. KWQC reported it was the 49th show, with more than 225 vendor booths. Check with QCBR for next year's dates.
Going to a show or not, use February to make a short list:
- Which rooms are too dark, too bright or too cold?
- Which way does each window face?
- Which windows face a neighbor, a street or a busy yard?
- Which rooms will you use most this spring and summer?
With that list in hand, any talk about window coverings goes faster. You're also less likely to buy something that solves the wrong problem.
How do I handle south-facing river glare in spring and summer?
On the Iowa side, glare is the big summer story. River rooms face south, so the sun crosses right in front of them. The water adds a second dose by bouncing light back into the room. In many river rooms, glare starts in early spring and hangs on into September.
You don't have to give up the view to fix it. A few options:
- Sheer shades soften the light. You still see a clear outline of the river through the fabric.
- Solar shades cut glare and heat while you see out during the day. Darker fabrics often give a clearer view than light ones.
- Top-down bottom-up shades let you lower the top to block the band of bright sky. The lower view stays open.
On the Illinois side, summer is easier on river rooms. North windows rarely get direct sun. The trouble there usually comes from east and west windows on the other sides of the house. That's where morning and late-day sun come in low.
For the hottest rooms anywhere in the Quad Cities, think about when the room gets used. A family room that sits empty until 6 p.m. can get by with a lighter shade. A west-facing home office used all afternoon needs more.
What changes when the house fills up for Tug Fest weekend?
In August, LeClaire takes on Port Byron in Tug Fest. Port Byron sits right across the river in Illinois. It's a tug of war across the Mississippi. KWQC calls it "the only event that shuts down the Mississippi River" for a tug of war. The 2025 contest was the 38th.
Big summer weekends like that put real pressure on the house. So does any week when family comes to stay. Bedrooms get used by people on different schedules. Living rooms fill up in the hottest part of the day. Sliding doors open and close all day long.
A few things to check before a busy summer weekend:
- Guest and kids' bedrooms: room-darkening shades help late sleepers when the summer sun comes up early.
- The main gathering room: light-filtering shades keep the room bright without the glare.
- Patio and sliding doors: pick something that moves out of the way fast so the door stays in use.
- Cords: if young grandkids are visiting, cordless options make sense.
What happens to light and privacy when the trees go bare?
Late October and November bring a change a lot of people don't see coming. All summer, your trees were doing part of your shading. They were giving you privacy too. When the leaves drop, the light changes. So does what the neighbors can see.
You might notice:
- Rooms that felt shady in July suddenly get direct sun.
- A window that looked out on green now looks straight at the house behind you.
- On the Iowa side, the river view opens up. So does the glare off the water, since the sun now sits lower in the south.
Low fall and winter sun also reaches farther into rooms than summer sun. In November a south-facing room can get light across the whole floor. In June that light barely made it past the sill.
This is a good time for an evening walk around the house with the lights on. From the yard, look at which rooms you can see into. Those rooms need a privacy layer. That could be a shade you close at night. Or try a top-down bottom-up shade that keeps the bottom covered.
Bare trees also show off homes built on slopes. In LeClaire's Cody Road Historic District, the ground drops sharply toward the river. The National Park Service record notes that many buildings on the river side have walk-in basements at the back. Homes like that have lower-level windows that may sit in full view once the leaves are gone. Our guide to lower-level windows in Bettendorf and Davenport covers small, high and walkout windows.
How do I plan one room at a time across the year?
You don't have to do the whole house at once. Here's a simple way to plan:
- List your rooms. Note which way the main window faces.
- Pick each room's hardest season. For a south river room on the Iowa side, that's usually summer glare. For a north room on the Illinois side, it's usually winter gloom. For a bedroom, it's whichever season the sun wakes you up.
- Choose for that season first. Then check that the covering still works the other three.
- Add layers where needed. A drape over a shade can cover two seasons with one setup. So can a top-down option.
- Start with the room you use most.
Your home's layout matters too. A big share of Bettendorf's houses went up in the 1960s and 1970s. Think big picture windows, long rows of bedroom windows and half-flight landings. Our guide to ranch, split-level and bi-level window ideas walks through each layout.
What does a Quad Cities year look like at a glance?
| Season | Main window job | Iowa-side river room (faces south) | Illinois-side river room (faces north) | Coverings to consider |
|---|---|---|---|---|
| Winter (Dec to Feb) | Hold heat, let in daylight | Open by day for sun, close at night | Clear the glass fully by day, close at night | Cellular shades, lined drapery |
| Spring (Mar to May) | Get ahead of stronger sun | Glare starts; add a sheer or solar layer | Usually comfortable | Sheer or solar shades, top-down bottom-up |
| Summer (Jun to Aug) | Control glare and heat | Glare plus light off the water | Watch east and west windows instead | Solar shades; room-darkening in bedrooms |
| Fall (Sep to Nov) | Privacy as leaves drop, prep for cold | Lower sun, more glare off the water | Less tree cover, more exposure at night | Top-down bottom-up, drapery, cellular |
Where should I start?
Start with the room that bugs you most right now. With winter coming, that's often a cold room or a dim one. It might be a room that suddenly feels exposed now that the trees are bare.
