Planning to visit Ames or just organizing your day? Here you'll find the latest weather information, including current readings and a detailed forecast.

The climate in Ames can be described as humid continental with four distinct seasons. The weather here is dynamic and varied, so travelers should be prepared for significant contrasts throughout the year. Winters are typically freezing, while summer brings genuine warmth and sunny days, creating excellent conditions for outdoor activities.

The warmest period occurs during the summer months, when average daytime temperatures hover around 23–24°C, reaching up to 29°C at their peak. Conversely, winter requires warm clothing, as temperatures consistently stay below freezing, dropping as low as -10°C in January.

The transitional seasons also have their unique characteristics. Spring arrives with gradual warming, but May stands out as the rainiest month of the year, with up to 14 days of precipitation. September often provides pleasant weather with comfortable temperatures around 20°C before autumn fully takes hold, bringing a crisp coolness to the air.

The climate in Ames features distinct seasonality, offering travelers a full range of weather conditions throughout the year. The annual temperature chart shows a significant contrast: from freezing winter months to truly hot summers. The coldest time of year is traditionally January, when the average temperature drops to -5.9°C, and nighttime lows can reach -10.0°C. In contrast, the heat peaks in July, which features sunny weather and average readings of around 24.1°C.

The summer season in the city, lasting from June to August, is characterized by high daytime temperatures, consistently reaching 28°C — 29°C. This time is ideal for those who love the heat; however, daily fluctuations should be considered: after sunset, the air becomes noticeably fresher, cooling down to a comfortable 18°C — 19°C. Fortunately, the summer warmth lingers into early autumn—September maintains high figures with daytime highs around 25.9°C, offering a mild transition to the cooler season.

Winter in Ames requires warm clothing, as sub-zero temperatures prevail from December to February. Even during the day, the thermometer rarely rises above freezing during these months, and January and February remain the harshest periods. Spring warming occurs gradually: March is still chilly, but by April the air warms up to 15.8°C during the day, and May greets visitors with a comfortable 22.5°C, marking the definitive arrival of the warm season.

Precipitation in Ames is unevenly distributed throughout the year, which is directly linked to the distinct change of seasons. The winter months, especially December, January, and February, are characterized by the lowest amount of precipitation. However, due to the freezing temperatures during this time (averaging from -0.9°C to -5.9°C), moisture falls primarily as snow. Despite the low volume of precipitation, there are about 6–7 days with precipitation per month in winter.

With the arrival of spring, the situation changes, and the city enters its wettest period. The peak of rainy weather occurs in May, which holds the record for precipitation frequency—averaging about 14 rainy days. During this time, as well as in June (11 days with precipitation), rain occurs quite often, providing the greenery with necessary moisture before the summer heat arrives.

In summer and early autumn, precipitation becomes more moderate but remains regular. In July and August, it rains about 9–10 days a month, often in the form of brief showers that bring freshness to warm days. By November, the number of wet days decreases again to the winter minimum (about 6 days), marking the transition to a drier and colder season.

When packing for Ames, it's essential to consider the distinct seasonality of the local climate. Winters can be quite freezing, so for a trip from December to February, be sure to pack a warm windproof jacket or down coat, a hat, scarf, and gloves. Given that temperatures can drop to -10°C, thermal underwear and insulated footwear will be very helpful for comfortable walks around the city.

In summer, the situation changes drastically: in July and August, the temperature often reaches +29°C. During this period, you will need light clothing made of natural, breathable fabrics, sunglasses, sunscreen, and a hat to protect yourself from the intense sun. Since Ames is a very walkable city, bring comfortable flat shoes regardless of the season.

Spring and autumn can be unpredictable, so the best wardrobe strategy is layering: a T-shirt can be paired with a sweater and a light jacket that’s easy to take off when it gets warmer. Pay special attention to rain protection, especially if your trip falls in May or June—the rainiest months of the year. A compact umbrella or a high-quality raincoat should definitely be on your list.
