Precipitation Patterns
Rain happens more often in early summer than later on. Independence sees about 92 mm (3.6 inches) of rain in July, spread across 10–11 days.
Most of that comes from quick thunderstorms, not all-day rain. These storms pop up fast in the afternoon heat, dumping heavy rain and some lightning.
You won’t see snow or other wintry stuff in July—just rain. If you’re spending the day outside, a light rain jacket or umbrella isn’t a bad idea.

Mornings can feel sticky, and afternoons sometimes get oppressive during heat waves. Evenings offer a little relief, but the air stays damp.
High humidity means sweating doesn’t cool you off as much. So, if you’re outside, drink water and look for shade now and then.

The sun rises around 5:55 a.m. and sets close to 8:45 p.m.

The long evening twilight makes it easier to hang out outside without turning on the lights until late.

Humidity, Pressure, and Wind Conditions
In early July, Missouri serves up muggy air, steady pressure, and light to moderate winds. These factors really shape how comfortable you’ll feel during holiday gatherings and events.

You’ll probably notice it most in the afternoon when heat and humidity peak together.
Mornings feel a little better, with dew points in the upper 60s. By midday, dew points can jump into the low 70s, making things feel quite humid.
If you’re planning to be outside, shoot for shaded spots or head out in the early evening. Late afternoon is often the stickiest and least comfortable.
Atmospheric Pressure Patterns
Atmospheric pressure in Missouri in July usually holds steady, averaging around 30.0 inHg (1016 mb). Summer brings big high-pressure systems that keep things stable across the central U.S.
You’ll notice pressure changes mostly when a front or storm system moves in. A drop in pressure often signals incoming thunderstorms, which are pretty common on summer afternoons.
Most of the time, pressure shifts are minor, so the weather feels consistent for several days unless a storm rolls through.
Typical Wind Speed and Direction
Winds in Independence in early July are usually light to moderate, with average speeds from 6 to 10 mph. That’s enough for a little relief from the heat, but nothing too wild.
The wind usually comes from the south to southwest in summer. This brings in warm, moist air from the Gulf of Mexico, which adds to the muggy feeling.
During storms, wind gusts can briefly top 20 mph. Otherwise, breezes stay gentle—nice for outdoor gatherings or fireworks.
UV Index and Sun Exposure
Early July in Independence, Missouri, means sunlight is about as strong as it gets. You’ll see long daylight hours, high UV readings, and a need to plan if you’re outside much.
Average UV Index Readings
Around Independence Day, the UV Index in Independence usually lands between 9 and 10, which is considered very high. These numbers are typical for midsummer, with the sun high and days long.
At this level, unprotected skin can burn in just 15–25 minutes. Even if it’s partly cloudy, UV rays stay strong since they get through thin clouds.
Surfaces like water, concrete, and light pavement bounce sunlight back at you, so exposure goes up.
The UV Index runs from 0 (low risk) to 11+ (extreme risk). A 9 or 10 means you should limit direct sun, especially from 10 a.m. to 4 p.m. when UV is at its worst.
Recommended Sun Protection
You really need to protect yourself when UV is this high. Broad-spectrum sunscreen (SPF 30 or higher) is a must—reapply every two hours, or after swimming or sweating.
Wear UV-blocking sunglasses, a wide-brimmed hat, and lightweight long sleeves for extra protection. Don’t forget about shade, especially during midday.
If you’re planning outdoor activities like barbecues or fireworks, try to schedule them early or late in the day. That way, you dodge the worst of the UV.
Kids and people with fair or sensitive skin should be extra careful—they burn faster.
Rainfall and Storm Probability
Summer in Missouri brings plenty of rain showers and a good chance for thunderstorms. Early July often mixes warm temps with moderate to high rainfall.
Average Rainfall Amounts
In Independence, July is one of the wetter months. Weather records show about 110–120 mm (4–5 inches) of rain for the month, usually spread over 9 to 11 days.
Most of this comes in short, heavy bursts. Afternoon and evening showers happen more often than morning rain.
Humidity means storms can dump a lot of rain fast.
Compared to spring, July’s rainfall is a bit less than the May peak, but it’s still significant. If you’re planning something outside, expect some chance of wet weather. A light raincoat or a covered option nearby is smart.
Chance of Thunderstorms
Thunderstorms are just part of Missouri summers, and July is no different. On average, about a third of rainy July days bring thunderstorms.
These storms usually pop up late in the afternoon when it’s hottest.
Most storms don’t last long—less than an hour—but they can bring heavy rain, gusty winds, and lightning. Severe storms with hail or damaging winds are less common, but they do show up sometimes.
Independence sits in a spot where Gulf moisture and warm air meet, making storms more likely. Checking local forecasts helps you plan safer outdoor fun.

If you want to catch parades, fireworks, or outdoor concerts, plan ahead. Spots in Independence and around Kansas City fill up fast, so try to get there early and give yourself some time to park and get settled.
Wear lightweight clothes, but honestly, toss a light jacket or poncho in your bag too. July gets hot, usually in the upper 80s or low 90s °F, and the humidity can make it feel even warmer.
Don’t forget to stay hydrated, especially if you’ll be outside for hours. Pack a small cooler with water and some snacks.
Most venues let you bring folding chairs or blankets, which really help when you’re waiting around. If fireworks are in your plans, check the local rules about sparklers or grills, since every city seems to do things a little differently.

Weather Considerations for Travelers
If you travel around Missouri in early July, you’ll probably run into traffic delays. Highways leading into Independence get especially busy. Afternoon thunderstorms pop up a lot, so you might want to give yourself extra time in case driving gets slow.
Always check the forecast for both your route and where you’re headed. Sometimes a storm hits one county and causes delays, even if your skies look clear when you leave. I’d keep an eye on radar updates, especially if you’re driving a long way.
Flying? You might see flight delays at Kansas City International Airport when severe weather moves in. If you’re renting a car, double-check that the air conditioning works. The heat during the day can be pretty rough.
