The climate in Gallup, located in the United States, is characterised as arid or semi-arid, with clearly defined seasons. The city experiences significant temperature fluctuations throughout the year, while total precipitation remains extremely low across all months. This means the air here is predominantly dry, and there are usually plenty of sunny days.

Four seasons can be distinguished in Gallup. Summer, especially in June, July, and August, is hot and dry, with average temperatures exceeding 20°C and daytime highs often reaching 29-30°C. Winter, in contrast, is cold, particularly in December and January, when average temperatures drop to -1°C and night frosts are a common occurrence. Spring and autumn are transitional periods with more moderate, yet still significantly fluctuating temperatures.

The most notable feature of the weather in Gallup is the extremely low level of precipitation year-round. In most months, only 1 mm of precipitation falls, and in some, such as April, May, and June, there may be none at all. Even in months with the highest number of "wet days," such as March and July (9 days each), the total amount of precipitation remains minimal, indicating very light or brief rains. Travellers should take these conditions into account and be prepared for sunny, dry weather and significant daily temperature changes.

The city of Gallup, USA, experiences a climate with pronounced seasonal temperature fluctuations. The warmest month is July, when the average temperature is 23.7°C, and daytime highs average 30.2°C. On the other hand, January is the coldest month with an average temperature of -1.0°C and nightly lows dropping to an average of -6.6°C. Such a significant annual temperature range means that travellers should carefully select their wardrobe depending on the season of their trip.

The summer period in Gallup, covering the months from June to August, is characterised by warm and sometimes hot days. Average maximum temperatures hover around 29-30°C. However, a distinctive feature of Gallup's climate is the substantial diurnal temperature amplitude. For instance, in July, despite the daytime heat, nights can be quite cool, with average minimums around 17.2°C. A similar pattern of warm days and significantly cooler nights is observed throughout the year, and the difference between day and night temperatures often exceeds 10-15°C.

Winter in Gallup, from December to February, is generally cold. Average temperatures stay around zero or slightly below, with January being the frostiest. Nighttime temperatures regularly drop below freezing, averaging -6.6°C in January and -4.7°C in February. Daytime highs in winter usually vary from 4.5°C to 7.3°C, so warm clothing will be absolutely necessary. Just like in summer, significant temperature drops between day and night persist during the cold season as well.

The city of Gallup, USA, has a fairly arid climate with low precipitation levels throughout the year. The total amount of precipitation is extremely small, making the city one of the drier regions.

The driest period in Gallup falls during the spring and early summer months. In April, May, and June, the average monthly precipitation is 0 mm, while the number of days with precipitation is minimal – just 2-3 days. This means that precipitation is practically non-existent during these months. Precipitation occurs somewhat more frequently in March and July, when up to 9 days with precipitation are registered; however, even during these periods, the total amount remains very low, only about 1 mm. This suggests that when precipitation does occur, it is usually very light.

The nature of precipitation changes depending on the season. During the winter months – December, January, and February – average temperatures drop below zero, especially the minimums, so precipitation falling on an average of 5-6 days per month is most likely to be in the form of snow. In transitional months, such as November and March, when minimum temperatures can be freezing, both light rain and snow are possible. During the rest of the year, especially in the warm summer months (July, August), any precipitation falls as rain, likely as brief and non-intense showers or drizzle, given the small total amount.

Thus, the driest months in Gallup are April, May, and June. Although no month can be called truly wet in terms of precipitation volume, March and July stand out with the highest number of days with precipitation, but even then, they are characterised by a very insignificant amount of moisture. In winter, the most probable form of precipitation is snow.

When planning a trip to Gallup, it is important to consider the significant temperature fluctuations throughout the year and even within a single day. The principle of layering clothing will be your best friend. In summer, especially from June to August, daytime temperatures can reach +30°C, so light breathable clothing such as t-shirts, shorts, and sandals will be appropriate. However, evenings can be cooler, so a light jacket or sweater will come in handy. Regardless of the season, do not forget sunscreen, sunglasses, and a hat, as the sun can be intense. Comfortable walking shoes are a must if you plan to explore the surroundings.

The winter months, from December to February, are quite cold in Gallup, with average temperatures around 0°C and night frosts down to -6°C. You will need a warm jacket, sweaters, a hat, gloves, and a scarf. Although precipitation is low (about 1 mm per month), it can fall as snow, so waterproof shoes will be useful. In the off-season, spring (March-May) and autumn (September-November), the weather is changeable. Days can be warm, especially in May and September, but mornings and evenings are noticeably cooler. It is recommended to bring both light items and warmer layers, such as a fleece top or a mid-season jacket.

Although heavy rains are rare in Gallup, a small amount of precipitation is distributed over several days each month, especially in July and the winter months. Therefore, a compact umbrella or a light waterproof windbreaker may prove useful without taking up much space in your luggage. Given the low humidity and possible wind, especially in the transitional seasons, lip balm and moisturiser may also be useful for a comfortable stay.
