Weather in Tulsa in June

Shoulder season. June sits in between. You will get good days and you will lose some. Highs average 31.3 °C, lows 20.5 °C, and rain falls on 11 days — nothing in the month is working against you.

June ranks 7 of 12 in Tulsa: past the worst of the year but short of October, which is the month to book if the dates are open.

Rain on 11 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 31.3 °C days and 20.5 °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: 19 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest June day reached 42.2 °C and the coldest night fell to 10.9 °C, and the wettest single day dropped 54 mm — roughly 48% of the month's rain in one day.

June is moderately variable: 40 mm in the driest year against 280 mm in the wettest, around an average of 113 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind is light at 11 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 72%.

How June sits in the year

The month is on the way up: 5.1 °C warmer than May, and July adds another 3.5 °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 Tulsa's year: 14.6 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

With no coast nearby, the year swings a fair way — 37.2 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

June in Tulsa versus nearby

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

So: June is a compromise. October is 24 points better and is what Tulsa is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
