Weather in Des Moines in June

A good month. June is a solid month to be in Des Moines. Highs average 27.8 °C, lows 16.6 °C, and rain falls on 14 days — nothing in the month is working against you.

June ranks 5 of 12 in Des Moines: past the worst of the year but short of September, which is the month to book if the dates are open.

This is wet-season rain: 14 wet days and 5 genuinely heavy ones, which in this climate means concentrated downpours rather than all-day grey. The pattern is usually a clear morning and a loud afternoon, so front-load the day and stop fighting the 3pm hour. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: 9 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest June day reached 39.6 °C and the coldest night fell to 5 °C, and the wettest single day dropped 54 mm — roughly 42% of the month's rain in one day.

June is moderately variable: 34 mm in the driest year against 308 mm in the wettest, around an average of 130 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind is light at 10.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 74%.

How June sits in the year

The month is on the way up: 5.4 °C warmer than May, and July adds another 2.7 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in June

June is at or near the longest days of Des Moines's year: 15.2 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

Des Moines has no sea to moderate it, and it shows: 40.3 °C separates the hottest afternoon of the year from the coldest night. That is a genuinely continental range, and it means summer and winter here are barely the same place.

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.

June in Des Moines versus nearby

If Des Moines is one option among several, the nearby comparison is worth making. Omaha is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Kansas City is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: June works, with September the better month by 13 points if the dates can move. If they cannot, nothing here should stop you booking.
