Weather in Oklahoma City in April

United States · 20-year averages, April

Prime time. April is about as good as Oklahoma City gets. Highs average 22.7 °C, lows 9.4 °C, and rain falls on 8 days — nothing in the month is working against you.

April is the highest-scoring month of the twelve. The nearest rival is October, and the month at the other end of the year is July.

Rain on 8 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest April day reached 37.6 °C and the coldest night fell to -4.3 °C, and the wettest single day dropped 58 mm — roughly 66% of the month's rain in one day.

April is moderately variable: 10 mm in the driest year against 183 mm in the wettest, around an average of 88 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 14.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 66%.

How April sits in the year

The month is on the way up: 5 °C warmer than March, and May adds another 4.3 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short. Rain is the thing that moves: May brings 5 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in April

13.1 hours of daylight, gaining 1.1 hours across the month. That is between Oklahoma City'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 — 37 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, September is the trade worth considering — 14 points weaker on weather, and materially quieter.

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

April in Oklahoma City versus nearby

If Oklahoma City 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, 2 days more rain. Wichita is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: April is the answer for Oklahoma City. If it is booked out or priced out, October is the next best thing at 0 points behind, and July is the month to keep off the shortlist.
