Weather in Tulsa in April

Prime time. April is about as good as Tulsa gets. Highs average 22 °C, lows 9.5 °C, and rain falls on 10 days — nothing in the month is working against you.

April ranks 2 of 12 in Tulsa. Only October scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 10 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 36.7 °C and the coldest night fell to -3.9 °C, and the wettest single day dropped 77 mm — roughly 73% of the month's rain in one day.

April is moderately variable: 35 mm in the driest year against 269 mm in the wettest, around an average of 105 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 14.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 72%.

How April sits in the year

The month is on the way up: 5 °C warmer than March, and May adds another 4.2 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in April

13.1 hours of daylight, gaining 1.1 hours across the month. That is between Tulsa's extremes of 14.6 and 9.7 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 37.2 °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 — 12 points weaker on weather, and materially quieter.

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

April 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, 2 days less rain. Wichita is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: April is effectively as good as it gets here — 1 points behind October, which is inside the margin where the weather stops being the deciding factor and price starts being it.
