Väder i Kansas City i september

Kansas City's forum treats September as the start of the good stretch between summer's humidity and winter's cold — mild enough for the Plaza Art Fair and Westport's outdoor events, with regulars steering visitors toward barbecue at Joe's or Jack Stack while the patio weather still holds.

Regulars planning an October trip lean hard on the region's harvest calendar rather than a downtown-only itinerary - a day trip to nearby Weston, roughly 45 minutes north, is a recurring recommendation, with an apple festival and an Irish festival both landing in the same window most years. Our row backs crisp, genuinely cool fall weather that suits the outdoor orchard-and-festival plan, 20.6C over 9.2C nights feeling 6C, with 71.2mm of rain across 5.7 days and an early trace of snow, 1.1cm, by month's end. A light jacket for the cooler mornings and evenings is standard advice even on an otherwise mild-feeling day. The record: humidity 64 percent, 8.1 hours of sun, an 18.8 kph wind and one of the cleanest air readings in this project, AQI 31.

Locals describe mid-April here as pleasant and the month as a whole as unpredictable day to day, with the advice to bring layers you can take off and put back on. Our row shows why both are true: 19.5C afternoons that read as 17C, 7.4C nights that read as 4C, and a 21.9 kph wind doing all of that subtraction. Spring is also the season they name for thunderstorms and tornado watches, so a forecast check is part of the day rather than a precaution. Rain is 73.2mm across 6.7 days and there is still 1.3cm of snow in the monthly average, which is the tail of winter rather than a likelihood. The record: humidity 63 percent, 9.3 hours of sun and AQI 41.

May is the month Kansas City regulars call lovely, and their one qualification is to bring something warm in case it turns cooler than you planned for - the city has had snow in May before, which they are quick to add is atypical. Our row gives the month a 24.6C average high and no snowfall at all, so treat that memory as the outlier it is. What they recommend doing with May is the gardens, because this is when they look their best: the grounds of the Nelson, the Kauffman Memorial Gardens and Loose Park, with the Plaza for everything else. The figure worth planning around is the rain, because 145.6mm across 10.8 days makes May one of the wettest months of the Kansas City year. The record: 13.9C nights, humidity 70 percent and 9.7 hours of sun.

Kansas City forum discussions describe January as the coldest month of the year, with an average temperature cited around 31F and roughly 4 days of measurable rain typical for the month. Posters were clear that winter here brings frequent, rapid swings between mild and genuinely cold days, and between wet and dry stretches, rather than settling into one steady pattern. Most of the city's snow falls in January and February, but it was described as usually wet, heavy snow that melts off fairly quickly rather than sticking around, and posters traveling through the region in January consistently recommended checking forecasts daily given how fast conditions can change.
