Is December Right for You?
Weigh the advantages and considerations before booking
Advantages
- + December is the driest month in Peoria. Only 10 rainy days means you can plan outdoor activities without constantly checking the forecast. Pack the sunscreen. Leave the umbrella at home.
- + Temperatures hover in the comfortable 70s°F (21-26°C) during mornings and evenings. Good for hiking the 500 m (1,640 ft) trails at Grandview Drive without overheating. The air feels soft. The views stretch for miles.
- + Holiday lights at the Peoria Riverfront Village turn the downtown riverwalk into a tunnel of LEDs and vintage riverboat horns. It's the kind of Midwestern kitsch that locals secretly love. Bring a camera. Smile at the glow.
- + Museums like the Peoria Riverfront Museum and the Pettengill-Morron House stay quiet this time of year. You can read the placards without a school tour group breathing down your neck. Take your time. Breathe in the silence.
Considerations
- − Afternoons spike to 101°F (38°C) with 70% humidity. The kind of heat that makes asphalt shimmer and turns the Peoria Zoo into a sauna by noon. Hydrate early. Seek shade.
- − UV index hits 8. Even short walks along the Illinois River will leave you sunburned if you skip SPF 50. Reapply every hour. The river reflects rays like a mirror.
- − Most outdoor patios cafes shut down patio seating by 3pm. Metal furniture gets too hot to touch. Move inside. Order iced tea.
Best Activities in December
Top things to do during your visit
Illinois River Bald Eagle Watching Tours
December is peak eagle migration. The birds ride south on the frozen Mississippi flyway and perch in the cottonwoods along Peoria's riverfront. Early morning boat tours leave from the dock under the Bob Michel Bridge when the water is still glassy and the eagles are most active. Bring binoculars. You'll spot 15-20 birds on a good day.
Booking Tip: Book 7-10 days ahead through licensed operators (see current options in booking section below). Request the 8am slot before river traffic kicks up. Dawn is golden. Eagles are hungry.
Downtown Peoria Food & Ale Trail Walks
With the patios closed, breweries like Rhodell and Obed & Isaac's shift to winter menus. Think pepper-pot soup and barrel-aged stouts. A self-guided walk between the five core downtown taprooms takes about 90 minutes and keeps you in air-conditioning between stops. December releases tend to be imperial stouts and barleywines that pair with the damp chill rolling off the river. Sip slowly. Warm your hands.
Booking Tip: No reservations needed for tasting flights. If you want the brewer-led tours (weekends only) book via the widget below a week out. Weekends fill fast. Plan ahead.
Forest Park Nature Center Winter Prairie Hikes
The 11 km (7 mi) trail system stays open year-round. December browns the tall-grass prairie into rustling waist-high waves. Mornings crunch with frost and you'll see deer prints in the mud along the Illinois River bluff trails. The visitor center hands out loaner trekking poles for the steeper 150 m (490 ft) elevation gain sections. Lace tight. Start early.
Booking Tip: Self-guided entry is free. If you want a naturalist-led prairie ecology walk, check the booking widget for weekend slots that typically run 10am-12pm. Guides know seeds. Stories develop.
Peoria Riverfront Holiday Lights Cycling
The 8 km (5 mi) riverfront path from RiverFront Village to the Gateway Building is strung with 250,000 LED bulbs that reflect off the water. Night rides start at 6pm when the heat breaks to 24°C (75°F) and you can coast without sweating through your jacket. Rent a fat-tire cruiser if the path is damp from river mist. Lights shimmer. Pedals turn easy.
Booking Tip: Bike rentals are first-come at the RiverFront kiosk. Arrive by 5pm on Fridays when locals get out of work and snag the cruisers first. Beat the rush. Claim your wheels.
Caterpillar Visitors Center Factory & Simulator Experience
Indoor climate-controlled exhibits let you operate a 797F mining-truck simulator. Perfect escape from the midday 38°C (100°F) spike. December weekdays are quiet enough that staff will let you retry the obstacle course without queuing. Shift gears. Laugh at the dust-free chaos.
Booking Tip: Reserve the 10am entry online (see booking section) to pair with lunch at the nearby Rhodell Brewery afterward when the heat peaks. Cold pint. Hot pizza. Repeat.

December Events & Festivals
What's happening during your visit
Early December
Santa Parade & Riverfront Lighting
First Saturday evening in December: marching bands, farm tractors wrapped in fairy lights, and Santa arriving by fire boat. Locals tailgate thermoses of hot cider along the riverwall. Bring a folding chair and arrive 45 minutes early for a spot near the Murray Baker Bridge. Bagpipes echo. Kids wave glow sticks.
Mid December
Dickson Street Victorian Christmas Walk
Historic Dickson Street mansions open for candle-lit tours with costumed docents and live harp music. The wood-burning fireplaces make the houses smell like pine and cloves. A sensory throwback that feels oddly moving in an age of LED bulbs. Step inside. Time softens.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
Locals do the RiverFront lights walk after 8pm when the tour buses leave. You get clearer photos and the synchronized music piped through the speakers is audible. Stay late. Hear every note.
Skip the mall cafes for lunch. The basement cafeteria at the Peoria Civic Center sells massive pork-tenderloin sandwiches to construction crews. Fastest, cheapest hot meal downtown. Line moves quick. Bring cash.
If you want a river-view table at Jim's Steakhouse, ask for the 'barge side' when reserving. It faces the floating docks, not the parking lot everyone else gets. Request early. Watch the water.
The Saturday farmers market (8am-noon, RiverFront) runs through mid-December. Buy frozen packets of summer sweet-corn kernels that locals hoard for Christmas dinner. Stock up. Taste July in December.
Avoid These Mistakes
Planning outdoor activities at 2pm. That's when Peoria's December heat peaks and even the squirrels hide. Schedule inside. Nap instead.
Assuming riverboat cruises operate year-round. Some docks pull boats for maintenance after Thanksgiving, so always double-check schedules in the booking widget. Verify first. Avoid disappointment.
Parking at the RiverFront garage for eagle tours. The lot opens late on weekends. Use the free spaces by the old power station instead and walk 400 m (0.25 mi). Save ten bucks. Stretch your legs.
