Richardson Weather: What to Expect Year-Round

Thinking of relocating to Richardson or planning to buy a home here? One of the smartest things buyers can do before making a move is understand what kind of weather to expect year-round. From sunny springs to hot Texas summers, the weather in Richardson, TX, plays a key role in lifestyle, home maintenance, and even energy planning.

Richardson is located in North Texas, just north of Dallas, and falls within a humid subtropical climate zone. This means the city experiences hot summers, mild winters, and variable rainfall throughout the year. With an average of around 230 sunny days annually, Richardson offers plenty of opportunities to enjoy outdoor activities—whether it’s walking the trails at Breckinridge Park or enjoying a patio dinner in CityLine.

Understanding the typical weather in Richardson, Texas, can help prospective homeowners plan for everything from landscaping and HVAC needs to seasonal wardrobe choices. Here’s a closer look at what to expect throughout the year.

Spring in Richardson is often described as one of the most pleasant times of year. Temperatures gradually rise from the mid-60s in March to the low-80s by May. This season also marks the beginning of the region’s thunderstorm season, so expect some windy days and occasional heavy rainfall, especially in April and May.

For locals, spring is when outdoor living hits its stride. Parks and green spaces fill up, festivals pop up across the city, and backyard gardens come alive. While humidity begins to increase, it’s still manageable compared to what’s ahead in summer.

Homeowner tip: Make sure your drainage systems and gutters are clear before spring showers arrive, as heavy rain can lead to minor flooding in lower-lying areas.

Summer in Richardson is hot, sunny, and often humid. Daily highs frequently reach the mid to upper 90s, with occasional heatwaves pushing temperatures past 100°F. July is typically the warmest month, and you can expect warm evenings that linger in the 70s.

While this is pool and lake season, it’s also when residents tend to adjust their routines—opting for early morning walks or late evening outings to avoid peak heat. Thunderstorms remain a possibility, although they’re more scattered and often short-lived.

Homeowner tip: For new homeowners, investing in a high-efficiency HVAC system and solid attic insulation can make a noticeable difference in comfort and energy costs during the summer months.

Fall in Richardson brings relief from summer heat and is widely considered a favorite season among residents. September starts off warm, but by late October and into November, daytime highs drop to the 60s and 70s, with cooler mornings in the 50s.

Rainfall is moderate during the fall, and sunny days remain common, making this season perfect for outdoor events, local festivals, and evening dining on patios. Fall foliage in nearby neighborhoods and parks adds a touch of color, although it’s typically brief.

Homeowner tip: Fall is a great time to check your home’s heating system before winter arrives and to prepare landscaping for cooler, drier months.

Richardson, TX's winter weather is relatively mild compared to other parts of the country. Average highs stay in the 50s and 60s, while nighttime lows occasionally dip into the 30s. Snowfall is rare but not impossible—typically, the city sees one or two light snow events each year, often melting within a day or two.

Icy conditions can occasionally affect driving or power lines, but they’re usually short-lived and manageable. Most residents don’t need heavy-duty winter gear, though a solid jacket and some layered clothing go a long way.

Homeowner tip: Make sure to insulate exposed pipes and know how to shut off your water line in case of freezing temperatures. Richardson’s brief cold snaps can still cause damage if homes aren’t winterized properly.

Understanding the typical weather in Richardson, Texas, helps future residents plan for both comfort and functionality. For example:

• Landscaping: Choose drought-resistant plants or native species to withstand summer heat and occasional dry spells.
• Home Design: Covered patios, energy-efficient windows, and shade trees are desirable features that add comfort and value.
• Commuting: With generally clear skies and minimal snowfall, weather rarely impacts driving conditions outside of isolated winter events.
• Activities: Golfing, hiking, and outdoor dining are common year-round, thanks to the city’s relatively moderate climate.

Seasonal awareness also affects utility planning. Air conditioning is essential during the summer months, so homes with newer HVAC systems, ceiling fans, and programmable thermostats are highly attractive to buyers and renters alike.

Over the past decade, Richardson has seen a slight increase in average annual temperatures, which is in line with broader climate trends across North Texas. While this hasn’t drastically altered the typical weather, it does mean summers may feel longer, and drought conditions could become more frequent.

Homebuyers are increasingly looking for energy-efficient features—like solar panels, radiant barriers, and smart thermostats—as a way to offset rising cooling costs. At the same time, homes with solid stormwater management systems and well-maintained roofs continue to be valued as weather-resilient properties.
