Weather in Wichita in September

A good month. September works. It is not the peak, but nothing about it fights you. Highs average 29 °C, lows 16.2 °C, and rain falls on 7 days — nothing in the month is working against you.

September ranks 3 of 12 in Wichita. Only October scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 7 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 29 °C days and 16.2 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 12 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest September day reached 42 °C and the coldest night fell to 5.5 °C, and the wettest single day dropped 81 mm — roughly 117% of the month's rain in one day.

September is moderately variable: 22 mm in the driest year against 175 mm in the wettest, around an average of 69 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 11.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 63%.

How September sits in the year

The month is on the way down: 4 °C cooler than August, with October dropping another 7.5 °C. The first week and the last are not the same trip. Rain has already shifted: 5 days fewer than August had.

Daylight in September

12.5 hours of daylight, losing 1.2 hours across the month. That is between Wichita's extremes of 14.8 and 9.6 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 38.7 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

September in Wichita versus nearby

If Wichita is one option among several, the nearby comparison is worth making. Tulsa is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Oklahoma City is close enough to be a coin toss — within a degree on temperature, 2 days more rain.

So: September works, with October the better month by 9 points if the dates can move. If they cannot, nothing here should stop you booking.
