In Vernal, USA, precipitation levels remain very low throughout the year. Monthly averages are only 1-2 mm, indicating a predominantly dry climate. There is no distinct rainy season here, although some months are characterised by a higher frequency of precipitation.

The highest amount of precipitation (2 mm) and the greatest number of days with it (about 12 days) usually occur in March. Given March's average temperatures, which are close to freezing (from -4.9°C to 6.6°C), precipitation during this period can fall as rain, snow, or sleet. The winter months — December, January, and February — are characterised by sub-zero average temperatures, so the little precipitation (about 1 mm per month, spread over 5-7 days) falls mainly as snow. November can also bring mixed precipitation as temperatures hover around the freezing point.

During the warm period, from April to October, precipitation falls as rain, but the amount remains minimal — about 1 mm per month. The frequency of rainy days varies during these months: for example, about 9 days in May, and 6-7 days in the summer months (June, July, August). The driest month in terms of precipitation frequency is September, with an average of only about 4 days with precipitation recorded, while the total amount is also around 1 mm. Overall, Vernal is characterised by rare and insignificant precipitation throughout the year.

When planning a trip to Vernal, it is important to consider its sharp continental climate with distinct seasons and significant temperature fluctuations throughout the year, while precipitation is minimal. In winter (December to February), you will be met with frost: average temperatures drop well below freezing (for example, in January the minimum temperature can reach -10.5°C). Be sure to pack very warm clothing: an insulated jacket, hat, gloves, scarf, and possibly thermal underwear. Despite the low precipitation (about 1 mm per month), it can be snow, so waterproof footwear will be very useful. Comfortable walking shoes are your faithful companion at any time of year.

Summer (June to August) in Vernal is hot, with daytime temperatures often exceeding +30°C, especially in July. Your suitcase should include light, breathable clothing, shorts, and T-shirts. Don't forget high SPF sunscreen, headwear (a hat or cap), and sunglasses. Evenings can be noticeably cooler, so a light cardigan or jacket will not go amiss. Spring (March-May) and autumn (September-November) are characterised by a wide range of temperatures: from cool mornings and evenings to warm days, especially in May and September. The layering principle is more relevant here than ever: T-shirts, long-sleeved shirts, a fleece or sweater, as well as a mid-season jacket. March and November are still quite cold, while late spring and early autumn will delight you with comfortable weather. Given the extremely low rainfall, an umbrella is unlikely to be needed, but a light windbreaker may come in handy for protection against the wind or rare, very light rain.
