Planning a trip or simply interested in the weather in Houston? In this section, you will find the most up-to-date information on weather conditions, detailed forecasts, and visual charts to help you stay informed of all changes.

The climate of Houston, located in the United States, can be described as humid subtropical. This means the city is characterized by hot and humid summers, as well as mild and short winters. Warm weather prevails throughout the year, making it attractive to visit in different seasons, though high humidity should be taken into account, especially during the summer months.

Seasons are clearly defined in Houston. Summer, lasting roughly from June to August, is the hottest period: the average air temperature holds around 28-29°C, while maximum values can reach 33-34°C. Winters, from December to February, are quite mild here, with an average temperature of about 12-15°C, and night frosts happen infrequently. Spring and autumn represent comfortable transitional periods with pleasant warm weather.

Regarding precipitation, it is distributed relatively evenly throughout the year, although the total monthly amount is small (from 2 to 6 mm). The number of days with precipitation ranges from 10 to 16 per month, with a slight increase in May and August. This means that while prolonged rains are unlikely, a light jacket or umbrella might be useful in any season.

The annual temperature regime in Houston is characterized by significant warmth throughout most of the year. The hottest month is usually August, when the average temperature reaches 29.4°C, and daytime highs often rise to 33.8°C. The coolest month is considered January with an average temperature of 12.7°C and nightly lows around 7.8°C. Thus, the annual range of average temperatures is about 17°C, indicating a distinct change of seasons despite the general warm trend of the climate.

Summer months in Houston, from June to August, are distinguished by consistently high temperatures. Average daytime values during this period range from 28.2°C in June to 29.4°C in August. Maximum temperatures regularly exceed the 30°C mark, peaking in August (33.8°C). Nights also remain very warm, with minimum temperatures rarely dropping below 24-25°C. Such weather, combined with the high humidity characteristic of the region, creates a sensation of a sweltering and quite stuffy summer.

Winter in Houston, covering the period from December to February, passes quite mildly. Monthly average temperatures at this time vary from 12.7°C in January to 14.9°C in December. Nighttime temperatures may drop to 7.8°C in January, but frosts are a rare phenomenon. During the day, the air warms up to a comfortable 17.5°C - 19.5°C. Noticeable temperature fluctuations between day and night are observed throughout the year: on average, the difference between maximum and minimum temperatures is about 9-10°C, providing some refreshment after warm days, especially in the transitional seasons and winter.

The nature of precipitation in Houston is distinguished by its presence throughout the year, without a clearly defined rainy season or prolonged drought. Nevertheless, data analysis shows certain patterns. On average, the amount of precipitation varies from 2 mm to 6 mm per month, and the number of rainy days ranges between 10 and 16. Given the predominantly warm climate of Houston, precipitation here falls in the form of rain.

Periods with the highest probability of precipitation fall in late spring and summer. Thus, May stands out as the wettest month by volume of precipitation, reaching 6 mm, and one of the leaders in the number of rainy days – on average 16. A similar picture is observed in August, where about 16 rainy days with 5 mm of precipitation are also recorded. July and September are also characterized by frequent rains, with 15 and 14 rainy days respectively, although the total millimeter count of precipitation in these months is slightly lower (4-5 mm).

Drier periods in Houston are observed in early spring and autumn. March is the month with the least amount of precipitation – only about 2 mm. The minimum number of rainy days, 10 in each, is recorded in October and November. In these months, as well as in February and April, the total volume of precipitation is also small, amounting to about 3 mm. This means that although rains become less frequent and their intensity is lower on average, there are practically no completely dry months in Houston, and brief rainfall is possible at any time of year.

When planning a trip to Houston, it is important to choose your wardrobe correctly, considering its warm and humid subtropical climate. In the summer months (June-August), when the average temperature stays around 28-29°C, and the maximum can reach 33-34°C, preference should be given to light, breathable clothing made of natural fabrics such as cotton or linen. Shorts, T-shirts, sundresses, and comfortable sandals will be most appropriate. Do not forget sunscreen with high SPF, a hat, and sunglasses for protection against the active southern sun. Since rainy days in Houston happen regularly (on average 10-16 days per month) throughout the year, even with a small total amount of precipitation, a compact umbrella or a light waterproof jacket will be a useful addition to your luggage. And, of course, comfortable shoes for long walks are an absolute necessity at any time of year.

In the transitional seasons – spring (March-May) and autumn (September-November) – the weather in Houston can be changeable, so the principle of layering in clothing will be the most practical. During the day, the temperature is comfortable, but it can be cooler in the morning and evening. Take T-shirts, long-sleeved shirts, light sweaters or fleece jackets, jeans or comfortable trousers, as well as a mid-season jacket. Winter (December-February) in Houston is mild, with an average temperature of about 12-15°C, however, night temperatures can drop to 7-10°C. For this period, warm sweaters, trousers, and an insulated jacket or coat, as well as closed shoes, are suitable. Regardless of the season, remember that air conditioners in buildings often work at full power, so a light cardigan or shawl may come in handy even on a hot day.
