The climate in Spokane is characterised as continental, with four distinct seasons. This means that significant temperature fluctuations are observed throughout the year, and each season brings its own unique weather.

Summer in Spokane is generally warm and very dry. July and August are the hottest months with an average temperature above +23°C and minimal precipitation. Winters, on the contrary, are cold; the average air temperature hovers around 0°C and sometimes drops lower. It is during the winter months, such as January and December, that the highest number of days with precipitation occurs, often falling as snow. Spring and autumn are transitional periods with more moderate temperatures and a gradual change in weather conditions.

The temperature pattern in Spokane demonstrates significant fluctuations throughout the year, which is characteristic of a continental climate. The hottest months are July and August. In July, the average temperature is +23.7°C, with daytime highs often reaching +31.3°C and nighttime lows dropping to +16.1°C. August is slightly cooler, with an average temperature of +23.1°C, a maximum of +30.5°C, and a minimum of +15.7°C. The coldest months are January and February, when the average temperature holds around -0.3°C. In January, the average minimum is -3.2°C, and the maximum is +2.5°C. February shows similar average values but with a lower average minimum of -4.2°C and an average maximum of +3.6°C. December is also cold, with an average temperature of -0.6°C (from -3.3°C to +2.0°C).

Summer in Spokane is thus characterised as hot and dry, especially during the daylight hours. The significant difference between day and night temperatures (about 14-15°C in July and August) means that a pleasant coolness follows a sweltering day. June is the prelude to the summer heat with an average temperature of +18.5°C, but already with noticeable daily peaks up to +25.1°C and nighttime temperatures around +11.9°C.

Winter months in Spokane, on the contrary, are frosty and snowy. The temperature stably holds around or below zero degrees. Night frosts are a common occurrence, and the thermometer regularly drops to -3°C...-4°C. Daytime temperatures in winter rarely rise significantly above zero. Daily temperature fluctuations in winter are less pronounced than in summer but are still present, averaging from 5°C to 8°C. Spring and autumn are transitional seasons with more moderate temperatures: for example, in April the average temperature is +8.3°C (from +2.6°C to +14.0°C), and in October +9.9°C (from +4.5°C to +15.4°C).

In Spokane, fairly clear seasonal fluctuations in precipitation distribution are observed throughout the year. One can distinguish a relatively wet period occurring in late autumn and winter, and a pronounced dry season in summer.

The greatest amount of precipitation, predominantly in the form of snow, falls during the winter months. January is the wettest month, when an average of 16 days with precipitation is recorded, although the total amount is about 3 mm. A similar picture is observed in December (3 mm of precipitation and 14 wet days) and November (3 mm of precipitation and 13 wet days). Given the average temperatures in these months (from -0.6°C to 2.8°C), precipitation here most often takes the form of snow or wet snow. February also brings snowy weather, with 12 days of precipitation and a total amount of about 2 mm.

Summer months, on the contrary, are characterised as very dry. July and August are the driest, with zero precipitation and only 1-2 days when minor rains are possible. This makes summer the ideal time for those who prefer sunny weather. The spring months (March, April, May) and early autumn (September, October) are transitional: the amount of rainfall here is moderate (1-2 mm), and the number of rainy days ranges from 5 to 10 per month, gradually decreasing towards summer and increasing towards winter.

When planning a trip to Spokane, it is important to consider its continental climate with distinct seasons. The key principle when packing your suitcase should be layering in clothing, as even in the warm season, evenings can be cool. Regardless of the season, comfortable walking shoes are your best companion for exploring the city. In summer, especially in July and August, when temperatures can rise above +30°C and there is practically no precipitation, be sure to take light, breathable clothing, sunscreen, a hat, and sunglasses. However, do not forget a light jacket or sweater for evening walks, as daily temperature changes can be significant.

Winter in Spokane (December-February) is quite cold, with average temperatures around zero and frequent snowfalls. You will need a warm winter jacket, a hat, a scarf, gloves, and waterproof shoes. Thermal underwear or extra layers of clothing will help keep you warm during walks. In the off-season (spring and autumn), the weather can be changeable. In March and November, it is still quite cool and precipitation is possible, so it is worth taking a mid-season jacket, a sweater, and perhaps a small umbrella. In April, May, September, and October, the weather is milder, but layering remains relevant – a T-shirt, a light sweater, and a jacket will allow you to feel comfortable throughout the day.
