The climate in Greeley can be described as continental semi-arid (steppe). This means the city experiences significant temperature fluctuations between seasons as well as throughout the day, while total precipitation remains low year-round. Visitors should expect clearly defined seasons with varying weather conditions.

Summers in Greeley (June-August) are hot and mostly dry, with average temperatures comfortably exceeding 20°C, and daytime highs often reaching or surpassing 30°C. Winters (December-February) are cold, with average temperatures around zero degrees Celsius, while nighttime temperatures regularly drop below freezing. Spring and fall are transitional periods with more moderate temperatures, warming up gradually in the spring and cooling down in the autumn.

A notable feature of the weather in Greeley is the low precipitation throughout the year. Even in months with the most "wet days," such as May, the actual amount of rainfall is minimal. This makes the weather generally sunny and dry, which is ideal for outdoor activities but requires proper preparation for sun protection and potential air dryness.

The city of Greeley experiences noticeable seasonal temperature fluctuations. The hottest months are traditionally July, with an average temperature of about 24.8°C and highs reaching 32.5°C, and August, where the average temperature is 23.8°C and the maximum is 31.5°C. The summer months, including June, are characterized by warmth that turns into heat, especially during the day. Nights bring significant relief as the temperature drops considerably, creating a noticeable diurnal range.

Winter in Greeley is cold. The frostiest months are January (average temperature -0.2°C, minimum -6.6°C) and February (average temperature -0.4°C, minimum -7.7°C). During these months, nighttime temperatures regularly drop well below freezing. December is also cold, with an average temperature of 1.6°C and lows down to -4.8°C. Daytime temperatures in winter can be slightly above zero, but overall the weather remains cool.

The transition seasons—spring and fall—show a gradual change in temperatures. March and April bring warming after winter, with average temperatures of 4.8°C and 10.0°C, respectively. In the fall, during September and October, the temperature begins to drop, averaging 20.4°C and 11.7°C. A characteristic feature of Greeley's climate is the significant difference between daytime and nighttime temperatures throughout the year, which is especially noticeable in the spring and autumn months when the daytime high can be 15-17°C warmer than the nighttime low.

The city of Greeley experiences a climate with relatively low precipitation throughout the year. There is no pronounced rainy season, but one can identify periods with slightly more precipitation and wet days. Overall, precipitation is fairly evenly distributed, except for the driest winter months.

The highest amount of precipitation falls in May, averaging 3 mm, and this same month is characterized by the highest number of wet days—about 11. March and June also see relatively more precipitation (2 mm). The driest months are January and December, when the average precipitation is 0 mm and the number of days with precipitation is minimal (3-4 days). A small amount of precipitation (1 mm) is also typical for February, April, and the period from July to November.

Given the temperature patterns, it can be expected that in the winter months (December, January, February), when average temperatures hover around zero or drop below, any precipitation that occurs is primarily in the form of snow. In March and November, with average temperatures around 5°C and minimums below zero, both rain and snow are possible. For the rest of the year, from April to October, when temperatures are much higher, precipitation falls as rain. The frequency of precipitation is low: for example, in May, the "wettest" month, precipitation is observed on about a third of the days, while in September and December, it's only 3-4 days.

When planning a trip to Greeley, it's important to consider seasonal weather changes so your wardrobe matches the conditions. In summer (June-August), it's warm and sometimes hot, with average temperatures reaching 21-25°C and maximum values above 30°C. It's recommended to bring light, breathable clothing made from natural fabrics, such as T-shirts, shorts, and sandals. Don't forget sunscreen, a hat, and sunglasses. Although rainfall is low, there are days with light rain, so a compact umbrella or a light waterproof jacket may come in handy. Comfortable walking shoes are a must any time of year.

Winter months (December-February) in Greeley are cold, with average temperatures around 0°C and nighttime frosts where the thermometer can drop to -6°C or lower. For this period, you'll need warm clothes: a winter jacket, sweaters, fleece tops, a hat, gloves, and a scarf. Thermal underwear will also be useful, especially if you plan to spend a lot of time outdoors. While heavy snowfall isn't common, light snow or sleet is possible, so waterproof shoes will be a good addition.

Spring (March-May) and fall (September-November) are transition seasons with changeable weather. Temperatures can fluctuate significantly throughout the day. It is still quite chilly in March and November, while May and September can offer pleasantly warm weather. The best strategy for these seasons is layering. Bring T-shirts, long-sleeved shirts, jumpers, and a mid-season jacket or windbreaker. This will allow you to easily adapt to temperature changes. A light scarf and hat may also be useful on cooler days.
