Summer, especially July and August, is the warmest and driest time of the year, when daytime temperatures reach an average of 29–30°C, and rain becomes a rare occurrence. However, it is worth noting a characteristic feature of the local climate: significant temperature fluctuations throughout the day. Even on hot summer days, nights can be quite fresh, so tourists are advised to carry warm clothing for evening outings.

The winter period, conversely, brings cooling with average temperatures around 0°C and frequent frosts at night. This time of year is also distinguished by the highest amount of precipitation: January and December are the "wettest" months, seeing up to 13–15 days with precipitation. Spring and autumn serve as mild transitional periods when nature awakens or prepares for winter sleep, offering tourists moderate weather for sightseeing.

Summer in the region is usually dry and sunny. During the day in July and August, the air often warms up to 29–30°C, creating a sensation of real heat. However, travellers should take into account an important feature of the local weather — significant diurnal temperature fluctuations. Even on the hottest summer days, the air cools quickly after sunset, and the night temperature can drop to a bracing 14°C, bringing welcome freshness.

The winter period here is cool, with daytime highs around 4–6°C, which requires warm clothing for walks. The transitional seasons, spring and autumn, pass quite smoothly. While March still reminds one of winter, by May pleasant weather sets in with daytime readings up to 19°C. September also remains a very comfortable month to visit, retaining summer warmth with daytime highs around 24°C before the onset of autumn cool in October.

Precipitation in Klamath Falls is distributed unevenly throughout the year, forming clearly defined wet and dry seasons. Travellers should note that the greatest number of days with precipitation falls during the winter period and early spring. Since night temperatures often drop below freezing (down to -3.3°C) in December, January, and February, there is a high probability of snowfall or sleet during this time of year.

The "wettest" month in terms of precipitation frequency is January, when inclement weather is observed for an average of 15 days. December and March are also distinguished by high humidity (13 days with precipitation). Despite the frequency, the total volume of precipitation remains moderate, which is typical for the climate of this region.

Summer, by contrast, delights tourists with stable and dry weather. July and August are the driest months of the year: rainfall levels tend towards zero during this time, and the number of rainy days is minimal — just 2–3 per month. This makes the summer season the most favourable time for visiting the region's natural attractions without the risk of getting soaked in the rain.

The transitional seasons demonstrate a gradual change in weather. In spring, the frequency of rains gradually decreases (from 10 days in April to 9 in May), and in autumn, starting from October, the number of cloudy days begins to grow again, reaching 11 days with precipitation by November.

When packing for Klamath Falls, it is important to consider the region's pronounced seasonality. Winters here are cool, with temperatures often dropping below freezing and a high probability of precipitation, so a warm windproof jacket, hat, and gloves will be simply essential. Since the number of wet days is quite high from November to March, be sure to ensure you have high-quality waterproof footwear to keep your feet warm and dry during walks.

In summer, the picture changes: the weather becomes dry and warm, with the air warming up to 30°C during the day, which calls for light clothing made from natural fabrics. However, remember the significant temperature drops: even in July and August, nights can be fresh, so a light fleece jacket or windbreaker will be useful for evening outings. Also, do not forget sunscreen and sunglasses in the summer season, as there are many sunny days and rain falls extremely rarely.

The best strategy for a tourist in the USA is to stick to the principle of layering in clothing to easily adapt to weather changes throughout the day. Comfortable walking shoes are mandatory in any season, as the region invites walking tours. If you are travelling in spring or autumn, take a compact umbrella or raincoat with you: the weather in the off-season can be changeable, and protection from rain will make your trip much more comfortable.
