Pueblo sits on western edge of the Great Plains in a high desert area of terrain in southern Colorado and is near the western edge of the Southwestern Tablelands ecology region. Pueblo has a steppe climate , with four distinct seasons. Winter days are usually mild, but the high does not surpass freezing on an average 15.3 days per year, and lows fall to 0 °F (−18 °C) or below on 7.8 nights. Snowfall usually falls in light amounts, and due to the high altitude, and the accompanying stronger sun, rarely remains on the ground for long (typically, for one or two days). January is the snowiest month, followed by March, and the seasonal average is 31.8 inches (81 cm); however, snow is uncommon in October, and in May or September, snow is exceedingly rare, with an average first and last date of measurable (≥0.1 in or 0.25 cm) snowfall being November 6 and April 13, respectively. Summers are hot and dry, with 90 °F (32 °C) or greater highs are on average seen 66.7 days per year, with 100 °F (38 °C) or greater on 10.2 days. Diurnal temperature ranges are large throughout the year, averaging 33.4 °F (18.6 °C).
Precipitation is generally low, with the winter months receiving very little. Sunshine is abundant throughout the year, with an annual total of nearly 3470, or 78% of the possible total. Pueblo is considered a high desert climate, and sits on the desert lands in southern Colorado between Pueblo and the Royal Gorge.
