Weather in Pocatello

Planning a trip to Pocatello? To ensure the weather doesn't take you by surprise, check the current forecast and detailed meteorological charts presented below.

The climate in Pocatello can be described as semi-arid continental, with distinct seasonal changes. For tourists, this means a significant contrast in temperatures throughout the year: here you will encounter both a truly frosty winter and a hot, sunny summer. Thanks to its location in an intermountain basin and low humidity, the local weather is usually perceived as comfortable.

Summer in the city, especially July and August, is a time of warmth and sunshine, when the air warms up during the day to an average of +30...+32°C. During this period, there is minimal rainfall, and there are very many sunny days, making summer the ideal time for active outdoor leisure. Winter, by contrast, brings stable cold weather: from December to February, average temperatures stay below zero, often dropping to -7°C, so warm clothing will be necessary.

Transitional seasons also have their own characteristics. Spring begins coolly, but by May it becomes significantly warmer, although this month accounts for the highest number of rainy days (about 12 days with precipitation). Autumn delights with mild and comfortable weather in September, but by November the temperature drops rapidly, reminding one of the approaching winter.

The climate in Pocatello is distinguished by pronounced seasonality, offering travellers diverse weather conditions throughout the year. The coldest month is traditionally January with an average temperature of about -3.4°C, while the peak heat falls in the middle of summer. The annual temperature range is quite wide, allowing tourists to catch both winter freshness and true summer heat.

The summer season here can be quite hot. In July, the warmest month of the year, the thermometer rises during the day to an average of 32.0°C. A characteristic feature of the local climate is noticeable temperature fluctuations throughout the day: even after a sweltering day, nights bring substantial relief when the air cools down to 16.1°C. Such a difference makes the evenings pleasant for walks.

The winter period is characterised by stable frosty weather. From December to February, average figures stay below zero, and at night temperatures often drop to -7.0°C. Transitional seasons also have their own features: May already pleases with comfortable warmth up to 19.2°C, and September often retains a summer mood with an average daily maximum of 25.0°C, before the autumn chill sets in.

Precipitation in Pocatello is distributed unevenly throughout the year, demonstrating clear seasonality. The winter period and the beginning of spring are characterised by the highest frequency of precipitation. Since the average temperature from December to February stays below zero (in January about -3.4°C), at this time the city is often covered in snowfall. January and May are the leaders in the number of inclement days — on average, precipitation is observed for about 12 days per month.

With the arrival of summer, the situation changes: a pronounced dry season sets in. July and September are considered the driest months of the year, when the number of days with precipitation decreases to a minimum — just about 4 days. At this time, rains, if they occur, are usually short-lived, which is excellent for walking and active recreation in nature.

Autumn serves as a transitional period: after a dry September, the number of wet days begins to gradually increase, reaching 8 days in November. Travellers planning a trip during the off-season or winter should be prepared for frequent changes in weather and precipitation, while summer tourists can count on predominantly clear skies.

The climate in Pocatello is characterised by distinct seasonality, so the contents of your suitcase will depend directly on your travel dates. A universal rule for travelling around this region of the USA is the principle of layering in clothing. This will allow you to easily adapt to temperature changes, which can be noticeable even within a single day. In addition, be sure to take comfortable flat shoes with you, as you will certainly want to walk a lot and explore local attractions.

If you are planning a visit in winter, from December to February, be prepared for sub-zero temperatures: you will need a warm winter jacket or down coat, waterproof shoes, a hat, a scarf, and gloves. Spring and late autumn here can be cool and damp, with a fairly large number of rainy days (up to 12 days a month), so a windproof jacket, a raincoat, or a sturdy umbrella will become important elements of your luggage.

Summer in Pocatello, especially July and August, is usually hot and dry, with daytime temperatures reaching +30°C and above. For this season, light clothing made from natural breathable fabrics, shorts, and T-shirts are best suited. Do not forget about sun protection: high-quality sunglasses, a hat, and SPF cream are mandatory, as precipitation at this time is minimal. However, even in summer, evenings can bring freshness, so taking a light jumper or hoodie with you would be a sensible decision.
