The precipitation pattern in Dallas shows some seasonal fluctuations, although without extreme peaks of humidity or drought. Throughout the year, the amount of falling moisture remains generally moderate. The greatest precipitation activity, both in volume and frequency, occurs in the spring months, while the summer period, especially its middle, is characterized by the least amount of rain.

The wettest month in Dallas is traditionally May. During this period, about 6 mm of precipitation falls on average, and the number of rainy days reaches approximately 13. Spring as a whole (from March to May) is distinguished by a higher probability of rain: in March and April, 4 mm of precipitation falls, with the number of rainy days ranging from 10 to 11. Conversely, the driest month is considered to be July, when only 1 mm of precipitation is recorded, although there are still about 7 rainy days. August and November also stand out as months with the fewest rainy days — only 6 days each, with 3 mm of precipitation falling in August and 2 mm in November.

Given the moderate amounts of precipitation even in the wettest periods, it can be assumed that rains in Dallas most often take the form of periodic or short-term showers rather than prolonged heavy rains. In the winter months (December, January, February), the total amount of precipitation is small and amounts to 2-3 mm, however, rainy days happen quite regularly — from 7 to 10 times a month. This may indicate a prevalence of light rains or drizzle in the winter season. Snowfalls are atypical for Dallas, as average winter temperatures usually remain above the freezing point.

When planning a trip to Dallas, it is important to consider its subtropical climate with hot summers and mild winters. In summer, especially from June to August, when the average temperature exceeds 30°C and the maximum can reach 35°C, you will need light, breathable clothing made from natural fabrics such as cotton or linen. Do not forget headwear, sunglasses, and high SPF cream, as the sun can be very active. Although summer is relatively dry in terms of rainfall, especially in July, short-term rains are still possible, so a light raincoat or a compact umbrella may come in handy.

Winter months in Dallas (December-February) are characterized by cool weather with an average temperature of about 8-11°C and night-time drops to 3-7°C. At this time of year, it is worth bringing sweaters, fleece tops, a mid-season jacket, and perhaps a light scarf and gloves, especially if you are sensitive to the cold. The principle of layering in clothing will be very useful here, allowing you to adapt to temperature changes throughout the day. Although heavy rains in winter are rare (2-3 mm of precipitation), there are 7-10 rainy days per month, so waterproof shoes and an umbrella will not be superfluous.

Spring (March-May) and autumn (September-November) are transitional seasons with comfortable temperatures. It is warmer in spring, but there is also more precipitation, especially in May (up to 6 mm and 13 rainy days), so a waterproof jacket or umbrella is mandatory. In autumn, the weather is drier and warmer at the beginning, gradually becoming cooler by November. Layered clothing is also recommended during these seasons: T-shirts, long-sleeved shirts, light jackets, or cardigans. Regardless of the time of year, comfortable walking shoes are an absolute necessity, as you will likely be walking a lot while exploring the sights of Dallas.
