Weather in Little Rock in September

A good month. September is a solid month to be in Little Rock. Highs average 31.2 °C, lows 18 °C, and rain falls on 8 days — nothing in the month is working against you.

September ranks 6 of 12 in Little Rock: past the worst of the year but short of October, which is the month to book if the dates are open.

Rain on 8 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 31.2 °C days and 18 °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: 6 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest September day reached 40.3 °C and the coldest night fell to 6.3 °C, and the wettest single day dropped 94 mm — roughly 107% of the month's rain in one day.

September is moderately variable: 8 mm in the driest year against 220 mm in the wettest, around an average of 88 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 1.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 68%.

How September sits in the year

The month is on the way down: 3.9 °C cooler than August, with October dropping another 6.6 °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

12.4 hours of daylight, losing 1.1 hours across the month. That is between Little Rock's extremes of 14.5 and 9.8 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 35.6 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself. September is the value pick for Little Rock: it scores within 14 points of October without carrying October's prices.

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

September in Little Rock versus nearby

If Little Rock is one option among several, the nearby comparison is worth making. New South Memphis is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Shreveport is the weaker option in September — within a degree on temperature, 1 day more rain.

So: September works, with October the better month by 14 points if the dates can move. If they cannot, nothing here should stop you booking.
