Climate Chart of Oklahoma City, USA

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

Monthly mean temperatures range from January at 4.2 °C to July at 28.5 °C. These are averages for each month, not daytime maximum temperatures, so they describe the broad temperature pattern rather than the full range visitors may encounter in a day. The unweighted mean of the monthly temperature means is 16.5 °C; it summarizes the calendar-month averages without weighting them by the number of days in each month.

Rain

Mean daily rainfall reaches its monthly high in May at 4.65 mm/day, while the lowest monthly mean is in January at 0.94 mm/day. These are daily mean amounts, not monthly totals, and they do not show how rainfall is distributed among individual days. Across the calendar months, the unweighted mean of those monthly daily-rainfall means is 2.36 mm/day; it should not be read as a day-weighted annual average or as a measure of how often rain falls.

Sunshine

Mean daily sunshine duration is highest in July at 12.02 hours/day and lowest in December at 6.78 hours/day. These averages describe sunshine duration, not day length, and do not establish how much sunshine any particular day will receive.

Snow

Mean daily snowfall peaks in February at 2.80 mm/day; the unweighted mean across the monthly snowfall means is 0.47 mm/day. Both are daily averages rather than monthly snowfall totals.

For visitors prioritising cooler monthly averages, January is the relevant option, with a monthly mean temperature of 4.2 °C. This average is not a daytime high or a forecast, so it cannot specify conditions for a particular visit. If lower average rainfall is the priority, January has the lowest monthly mean daily rainfall at 0.94 mm/day. That figure does not guarantee dry days or quantify rain frequency; for preparation, note that the highest monthly mean daily rainfall occurs in May at 4.65 mm/day.

For planning outdoor sightseeing around average sunshine duration, July records the monthly high at 12.02 hours/day, while December records the low at 6.78 hours/day. These are daily sunshine averages, not measures of daylight length or guarantees about conditions on individual days. Snowfall averages are greatest in February at 2.80 mm/day per day, but this monthly mean alone cannot indicate whether snowfall will occur during a specific trip.
