Key Takeaways
- September averages 66.2°F, while October averages 53.2°F, making early fall comfortable for walking, parks, and outdoor dining.

- Major 2027 dates include the Des Moines Arts Festival on June 25–27 and the Iowa State Fair on August 12–22.
- Winter brings the smallest leisure crowds but also the highest risk of snow, ice, and weather-related travel disruption.
Spring: March Through May
Spring works well if you want moderate temperatures, green parks, and city events before the summer peak. March remains changeable, April becomes noticeably milder, and May feels fully springlike. The trade-off is rain: according to the National Weather Service 1991–2020 Des Moines climate normals, May averages 5.24 inches of precipitation.
March and April: Mild Weather With Rapid Changes
March and April form Des Moines’ main transition from winter to spring. The normal monthly mean rises from 39.4°F in March to 51.3°F in April, so conditions become much more comfortable for walking as the season progresses. Cold snaps, rain, and occasional late snow are still possible.
- What to expect: March can shift between winter-like and spring-like weather. April is milder but wetter, with a normal 4.02 inches of precipitation.
- Things to do: Mix indoor stops such as the Des Moines Art Center and Science Center of Iowa with walks through the East Village and city parks on milder days.
- Major event: The 117th Drake Relays are scheduled for April 21–24, 2027. Expect stronger demand around Drake University during the event.
- Best for: Travelers who prefer fewer summer crowds and do not mind variable weather.
May: Green Parks and the Outdoor Season
May is one of the most attractive spring months, with a normal mean temperature of 62.4°F and much longer periods of comfortable outdoor weather. It is also one of the wetter months, so it suits flexible sightseeing better than travelers who require consistently dry conditions.
- Things to do: Walk or bike along river trails, visit the Greater Des Moines Botanical Garden, explore Pappajohn Sculpture Park, and use outdoor patios as weather permits.
- Farmers’ Market: The 2026 Downtown Farmers’ Market runs Saturdays from May 2 through October 31 in the Historic Court District.
- Seasonal events: The Renaissance Faire at Sleepy Hollow is another spring option, with programming traditionally held in May.
- Best for: Parks, gardens, markets, and travelers who want warm weather before midsummer heat.
Summer: June Through August
Summer offers Des Moines’ fullest event calendar, longest days, and warmest weather. June is especially active for arts and outdoor events, July has the highest normal monthly mean temperature, and August is dominated by the Iowa State Fair. These advantages also bring stronger crowds and lodging demand.
June: Festivals and Long Days
June averages 72.2°F and marks the start of true summer conditions. It is also the wettest month in the 1991–2020 normals by a narrow margin, averaging 5.26 inches of precipitation, so outdoor plans benefit from some flexibility even though there is plenty of warm weather.
The major city-center event is the Des Moines Arts Festival, scheduled for June 25–27, 2027 at Western Gateway Park. Admission is free, while food, beverages, merchandise, and art purchases cost extra.
- Good for: Festivals, outdoor dining, parks, cycling, concerts, and visitors who want a lively downtown.
- Trade-off: Festival weekends can increase downtown crowds and lodging pressure.
July: The Warmest Part of Summer
July has the highest normal monthly mean temperature at 76.0°F. Hot and humid afternoons are common, but long daylight hours make it easy to plan early-morning and evening activities. This is a strong month for parks, river recreation, baseball, outdoor concerts, and neighborhood events.
- Things to do: Picnic in city parks, explore trails, attend an Iowa Cubs game, or plan outdoor activities outside the hottest part of the afternoon.
- Best for: Travelers who prioritize long days and a busy summer atmosphere.
- Trade-off: Heat and humidity can make extended midday walking uncomfortable.
August: Iowa State Fair Season
August remains firmly in summer, with a normal mean temperature of 73.9°F. The biggest planning factor is the Iowa State Fair, which creates a clear spike in crowds and accommodation demand. Travelers who are not attending the Fair may prefer dates before or after its run.
The official Iowa State Fair schedule lists the 2027 Fair for August 12–22. The Fair is a ticketed event and draws visitors from across Iowa, the Midwest, and beyond.
Another major late-summer event is the World Food & Music Festival. The latest confirmed edition ran August 28–30, 2026 at Western Gateway Park and was free to attend.
- Best for: State Fair visitors, food events, summer entertainment, and travelers who enjoy a busy atmosphere.
- Trade-off: August has some of the year’s strongest event-driven crowd and lodging pressure.
Fall: September Through October
Fall is the strongest all-around season for many Des Moines visitors. September stays warm enough for outdoor dining and parks, while October brings cooler air and changing leaves. Rainfall normals are lower than in late spring, and major summer-event crowds begin to ease.
September: The Best All-Around Weather Balance
September has a normal mean temperature of 66.2°F and 3.18 inches of precipitation. That combination makes it easier to spend long periods outside than during midsummer heat or wet late-spring weather. Evenings are cooler, but most daytime sightseeing remains comfortable.
- Things to do: Visit the Downtown Farmers’ Market, explore Pappajohn Sculpture Park, walk riverfront trails, or spend time at the Greater Des Moines Botanical Garden.
- Seasonal event: The Renaissance Faire at Sleepy Hollow is another September attraction.
- Best for: First-time visitors, outdoor sightseeing, couples’ trips, and travelers who want a balance of weather and activity.
October: Fall Color and Cooler Days
October cools to a normal monthly mean of 53.2°F and averages 2.78 inches of precipitation. It is a strong choice if fall scenery matters more than warm evenings. Layers become more important as the month advances, especially after sunset.
The Iowa Department of Natural Resources says the central third of Iowa typically reaches peak fall color during the first through third weeks of October, depending on weather.
- Things to do: Explore parks and trails, take a scenic drive outside the city, visit nearby orchards or pumpkin patches, and enjoy cooler-weather brewery or restaurant stops.
- Market season: The 2026 Downtown Farmers’ Market continues through October 31, with October hours starting one hour later than the May–September schedule.
- Best for: Fall foliage, seasonal activities, photography, and visitors who prefer crisp weather.
Winter: November Through February
Winter is the quietest choice for travelers who are comfortable with cold weather and want to focus on museums, performances, restaurants, and holiday events. Snow and ice are normal parts of the season, especially from December through February, so winter trips need more schedule flexibility than trips in fall.
November: The Shift Into Winter
November averages 39.3°F, making it much cooler than October but not yet as cold as midwinter. Snow becomes possible, with a normal monthly snowfall of 2.7 inches. Outdoor sightseeing can still work on mild days, while museums and cultural venues become increasingly useful.
- Things to do: Visit the Des Moines Art Center, Science Center of Iowa, State Historical Museum, local restaurants, coffee shops, and performances at the Des Moines Civic Center.
- Best for: Lower-key city breaks and travelers who prefer indoor attractions.
- Trade-off: Daylight is shorter, and weather can change quickly.
December: Holiday Events and Early-Winter Weather
December averages 27.7°F, with normal monthly snowfall of 7.9 inches. Holiday programming adds activity despite the cold, making December more festive than January or February. Warm clothing and waterproof footwear become much more important for anyone walking downtown.
Christkindlmarket Des Moines is scheduled at Principal Park for December 3–6 and December 10–13, 2026, giving holiday-focused visitors two long weekends to plan around.
- Things to do: Combine holiday markets and seasonal performances with museums, restaurants, shopping, and indoor attractions.
- Best for: Holiday atmosphere and short cultural trips.
January and February: Deep Winter and the Fewest Crowds
January and February are the coldest part of the Des Moines travel calendar. Normal monthly means are 22.3°F in January and 26.9°F in February, while normal snowfall reaches 9.4 and 10.2 inches respectively. These months favor indoor-heavy itineraries rather than long days outside.
- Things to do: Spend more time at museums, restaurants, breweries, theaters, basketball or hockey events, and other indoor attractions.
- Best for: Travelers prioritizing quieter conditions over outdoor sightseeing.
- Trade-off: Snowstorms and ice can affect road and air travel.

Budget and Accommodation
Des Moines prices are affected more by specific event dates than by a simple high-season/low-season pattern. The strongest pressure occurs around the Iowa State Fair and major downtown festivals, while January, February, and much of November generally bring less leisure demand. Spring and fall often provide the best compromise between weather and cost.
If you are attending a named event, booking earlier gives you more choice of location and room type. Outside major event weekends, you can usually be more flexible about which part of the city you stay in.
Weather and Packing
Des Moines has four distinct seasons, so packing changes substantially through the year. Layers are useful in spring and fall, while summer requires heat and sun protection and winter calls for genuine cold-weather gear.
- Spring, March–May: Pack layers, a light or medium jacket, comfortable walking shoes, and a rain-resistant outer layer.
- Summer, June–August: Choose light, breathable clothing, sunscreen, sunglasses, and a hat. A light layer is useful for air-conditioned venues and cooler evenings.
- Fall, September–October: Bring layers, long sleeves, and a medium-weight jacket. Late October may require warmer accessories.
- Winter, November–February: Pack a heavy coat, warm hat, gloves, scarf, insulated layers, and waterproof footwear.
Check the local forecast shortly before departure because day-to-day temperatures can differ sharply from the monthly averages.
Events and Festivals That Affect Your Dates

Which Time Is Best for Your Trip?
Your ideal dates depend on whether weather, events, price pressure, or seasonal scenery matters most. September is the strongest general-purpose choice, but June and August offer a busier event calendar, while winter rewards travelers who prefer quieter indoor-focused trips.
- For the best overall weather balance: Choose September or early October. Temperatures are comfortable, normal rainfall is lower than in May and June, and outdoor sightseeing remains practical.
- For spring scenery: Choose May, accepting a higher chance of rain in exchange for green parks, gardens, markets, and mild temperatures.
- For the liveliest event calendar: Choose late June or August. Plan around the Des Moines Arts Festival or Iowa State Fair if those events are part of your trip.
- For fall color: Aim for the first through third weeks of October. Peak timing varies with weather, so exact color conditions can shift from year to year.
- For lower leisure demand: January, February, and much of November are quieter, but outdoor options are more limited and winter weather can disrupt travel.
If your dates are completely flexible, September offers the easiest balance of comfortable weather, outdoor activities, active markets, and fewer extreme conditions.
