Climate overview
Temperature
The coolest monthly mean is 16.8 °C in January, while the warmest is 21.6 °C in April. These are averages for each month, not daytime maximum temperatures, so they describe the broad monthly temperature pattern rather than the hottest conditions a visitor might experience on a particular day. Across the calendar-month means, the unweighted mean is 19.0 °C. It is a summary of monthly averages, not a day-weighted annual average, and cannot describe the variation from one day to another.
Rain
Mean daily rainfall is lowest in February, at 0.03 mm/day, making it a conditional option for visitors who prioritise lower average rainfall. The highest monthly mean is 6.30 mm/day in September; allow for rain in plans then, while remembering that a daily mean does not show how often rain falls or guarantee conditions on a particular day. The unweighted mean across the monthly daily-rainfall means is 2.14 mm/day. This is a daily average, not a monthly rainfall total, and it does not reveal the timing or frequency of wet days.
Sunshine
Mean daily sunshine reaches its highest value, 11.22 hours/day, in April, and its lowest, 9.07 hours/day, in September. These figures can help with outdoor daylight planning, but sunshine duration is not day length and does not promise uninterrupted sun. The unweighted mean of the monthly sunshine-duration means is 10.27 hours/day per day. Treat it as a broad monthly-average summary rather than a prediction for any particular date.
Best Travel Time Guide for Oaxaca, Mexico: Ideal Seasons and Weather Insights
If lower average rainfall is your priority, February is the conditional option in these figures, with mean daily rainfall of 0.03 mm/day. That average does not guarantee dry days or indicate how frequently rain occurs, so keep plans flexible and check current forecasts. For the coolest monthly mean, consider January, when the mean is 16.8 °C; this is useful for comparing average conditions, but it is not a forecast of daytime highs or day-to-day weather. If planning outdoor sightseeing around sunshine duration, April has the highest mean at 11.22 hours/day, while September has the lowest at 9.07 hours/day—neither figure represents day length or guarantees clear skies. Rain preparation is especially relevant in September, the month with the highest mean daily rainfall at 6.30 mm/day. This does not mean it rains every day, but a light rain layer and adaptable outdoor plans are sensible; the figure is a daily mean, not a monthly total.
