Tucson, located in the state of Arizona, USA, is characterized by a typically desert climate. This means you can expect long periods of sunny weather, low humidity for most of the year, and significant temperature fluctuations not only between seasons but also between day and night. Prepare for bright sunshine and the dry air characteristic of this region.

Seasons in Tucson are clearly defined. Summer, especially from June to September, is very hot and sunny, with average temperatures often exceeding 30°C and maximums reaching 37°C. Winters here are mild and pleasant, with average daytime temperatures around 11-12°C, although nights can be cool with minimum temperatures around 4-5°C. Spring and autumn are transitional periods with comfortable temperatures, ideal for outdoor activities.

One of the features of Tucson's climate is the so-called "monsoon season," which usually falls in July and August. During these months, there is a slight increase in rainfall (up to 2 mm) and the number of rainy days compared to the rest of the year, although total precipitation remains low. Overall, Tucson is a place where dry and clear weather prevails for most of the year, making it attractive for sun lovers.

Tucson's climate demonstrates significant temperature fluctuations throughout the year. The hottest months are June and July, when the average daily temperature reaches its peak. In July, the average temperature is 31.0°C, while maximum readings often rise to 36.8°C. June is also very hot, with an average temperature of 29.7°C and maximum values around 37.0°C. The coolest period falls on December and January. In January, the average temperature drops to 11.0°C, and the average minimum night temperature is only 4.4°C, making it the coldest month of the year.

Summer months in Tucson, especially from June to August, are characterized by intense heat. Daytime highs consistently exceed 35°C (for example, in August the average maximum is 35.6°C), and average night temperatures remain quite high; for instance, in July it is 25.1°C. Winters, on the contrary, offer mild and pleasant daytime weather: in January and December, average maximum temperatures hold at a comfortable level of 17.6°C - 18.6°C. However, nights in winter become noticeably cool, with average minimum temperatures dropping to 4-5°C. This significant difference between day and night temperatures is particularly noticeable during the winter period.

A characteristic feature of Tucson's temperature regime is the substantial diurnal temperature range practically all year round. For example, in April, the difference between the average maximum (28.3°C) and average minimum (12.7°C) temperature is more than 15 degrees. Similar significant fluctuations are observed in other months, which is a typical feature of a desert climate. Spring months, such as March (average temperature 15.1°C) and April (20.5°C), as well as autumn months like October (22.4°C), offer more moderate temperatures, creating comfortable conditions between the summer heat and winter cool.

Tucson experiences pronounced seasonality in precipitation distribution, typical of a desert climate. For most of the year, dry weather prevails here, however, there is a noticeable, albeit brief, period of increased humidity known as the summer monsoon. Overall, the amount of precipitation in Tucson is low, making it attractive for lovers of sunny days.

The greatest amount of precipitation and rainy days falls on July and August. During these months, 2 mm of precipitation falls, which is the annual maximum for the city. More importantly, it is in summer that the frequency of rains increases sharply: usually, there are 11 rainy days in July and 12 in August. Precipitation at this time most often takes the form of short but sometimes intense downpours brought by monsoon flows. February also stands out with 2 mm of precipitation and 6 rainy days.

On the other hand, many months in Tucson pass almost without rain. April, May, June, October, and November are absolutely dry, with an average rainfall of 0 mm. During these periods, rain is a great rarity: April, May, and June count only one rainy day each, October has three, and November has two. Winter months (January, December) and early spring (March) bring a minimal amount of moisture – about 1 mm of precipitation and approximately 4 rainy days, which only slightly interrupts the generally arid picture.

When planning a trip to Tucson, it is important to consider its desert climate with hot sun and significant temperature changes during the day, especially between day and night. Regardless of the time of year, be sure to bring sunscreen with a high SPF, sunglasses, and headwear (such as a hat or cap) to protect against the intense Arizona sun. Comfortable walking shoes are your best friend for exploring the city and its surroundings. The principle of layering clothes will always be relevant: light items that can be put on or taken off depending on the weather will help you feel comfortable both during the day and on cool evenings.

If your trip falls during the summer months (June-September), prepare for intense heat, especially during the day when the temperature can reach 37°C. Pack light, loose clothing made from natural breathable fabrics such as cotton or linen. Shorts, t-shirts, and sundresses will be very appropriate. The monsoon season arrives in July and August, characterized by an increase in the number of rainy days. Although the total rainfall is low (about 2 mm per month), a light waterproof jacket or a small umbrella may prove useful for protection against short-term downpours.

Winters in Tucson (December-February) are quite mild during the day, with an average temperature of around 11-12°C, but nights can be quite cool, with temperatures dropping to 4-5°C. You will need jeans or trousers, long-sleeved shirts, sweaters, and a light jacket or fleece, especially for evening walks. Spring (March-May) and autumn (October-November) are pleasant transitional seasons with comfortable temperatures, but do not forget about layering here either, as evenings can be cool, while daytime temperatures, for example in April, can reach 28°C. Precipitation is minimal during these periods, but a light windbreaker or cardigan will always come in handy for comfort.
