Weather in Roswell

Stay informed about the current weather conditions in Roswell to ensure your journey is as comfortable as possible. Below you will find the latest data, detailed forecasts, and useful charts for planning your trip.

The climate in Roswell can be characterised as semi-arid, with distinct seasonal divisions. This region is typically characterised by an abundance of sunlight and low humidity, creating favourable conditions for travel at almost any time of year. The weather here is generally stable, without sharp and unpredictable fluctuations, allowing tourists to confidently plan outdoor activities.

Summer in the city is hot: in the warmest months, July and August, daytime temperatures often reach 35°C, while average figures hover around 27–28°C. Winter, on the other hand, is mild and quite comfortable, with average temperatures around 7–9°C. Although nights in the winter period can be cool (down to 0–2°C), during the day the air usually warms up to a pleasant 14–15°C, which rules out severe frosts.

A characteristic feature of the weather in Roswell is the extremely low amount of precipitation. Throughout the year, precipitation levels remain minimal (about 1–2 mm per month), although days with slight humidity occur periodically. This makes the climate dry and clear, so you are unlikely to need an umbrella, whereas sunscreen and headwear will be essential attributes of your trip.

The temperature regime in Roswell demonstrates pronounced seasonality with a noticeable difference between winter and summer. The annual cycle begins with the coldest month — January, when the average temperature is just 7.2°C. Gradually warming up, the air reaches its peak in July, which is the hottest month of the year with an average figure of 28.6°C and daytime highs regularly reaching the 35.0°C mark.

Summer in Roswell can be described as truly sweltering. In the period from June to August, the daytime temperature consistently stays in the range of 33-35°C, which requires tourists to protect themselves from the sun and plan activities for cooler hours. Winter, conversely, is quite mild: daytime temperatures in December and January often rise to a comfortable 14-15°C, however, nights can be chilly, with temperatures dropping almost to 0°C (the January average minimum is 0.5°C).

An important feature of the local climate is significant daily temperature fluctuations. The difference between the daytime heat and the night-time cool can be quite substantial. For instance, in June, after a hot day (around 35°C), the temperature at night drops to 20°C, and in the transitional seasons, such as in April or October, this drop is felt even more strongly, creating fresh and pleasant evenings after warm days.

The climate in Roswell is distinguished by pronounced aridity, so precipitation here is a rather rare and scarce phenomenon. Throughout the year, the volume of falling moisture remains consistently low, usually not exceeding 1–2 mm per month. This makes the city an excellent destination for travellers who prefer clear skies and want to avoid prolonged rains during their trip.

Despite the general dryness, a certain dynamic can be traced in the distribution of "wet" days. The peak frequency of precipitation falls at the end of summer: the rainiest month by number of days is August (about 8 days with precipitation). In the summer period, rains generally take the form of short-term thunderstorms, which bring only an insignificant amount of moisture and are quickly replaced by sunshine.

Winter months and late autumn, conversely, are the driest periods of the year. In January, November, and December, the minimum number of days with precipitation is recorded — on average just about 3 days per month. Considering that night-time temperatures in winter can drop to low values, light snow is theoretically possible, but due to the general moisture deficit, a stable snow cover practically never forms here.

When packing for Roswell, it is worth considering the peculiarities of the local climate: it has hot summers and rather cool winters with noticeable temperature fluctuations. For a summer trip (from June to August), when the air warms up to +35°C, be sure to take light clothing made from natural breathable fabrics, such as cotton or linen. The sun in New Mexico is very active, so a wide-brimmed hat, high-quality sunglasses, and high SPF sunscreen will become your indispensable companions.

If your trip is planned for winter or the shoulder seasons, the best solution will be the principle of layering in clothing. During the day it may be quite comfortable in a light jumper, but by night the temperature often drops to +2°C...+5°C, so a warm jacket, sweater, and scarf will be very useful. In spring and autumn, the weather is pleasant but unpredictable, so keep items at hand that can be easily put on or taken off depending on the time of day.

Regardless of the season, put comfortable, broken-in shoes in your suitcase for long walks, as you will surely want to explore the city and its surroundings on foot. Although very little precipitation falls in Roswell, a light windbreaker will come in handy for protection against the wind, which is characteristic of open spaces. Also, considering the rather dry desert air, do not forget to take moisturising cream and lip balm with you.
