Climate Chart of Xi'an, China

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

Climate overview

Temperature

Monthly mean temperatures are lowest in January, at 0.9 °C, and highest in July, at 27.7 °C. These values describe averages for each month, not daytime maximum temperatures, so they are useful for understanding the broad temperature pattern but cannot specify how warm or cool an individual day will feel. The unweighted mean of the monthly temperature means is 14.9 °C. It is a summary across the calendar months, not a day-weighted annual average.

Rain

Mean daily rainfall is lowest in January, at 0.07 mm/day, and reaches its highest monthly mean in September, at 4.06 mm/day. These are daily averages for the named months, not monthly rainfall totals; the lower average does not guarantee rain-free days, and the figures do not reveal how often rain occurs. The unweighted mean of the monthly daily-rainfall means is 1.88 mm/day. Use it as a broad summary, rather than a forecast for a particular day or a measure of monthly accumulation.

Sunshine

Mean daily sunshine duration is highest in July, at 9.93 hours/day, and lowest in October, at 6.06 hours/day. These averages can help describe the contrast in sunshine available for outdoor plans, but sunshine duration is not the same as day length and does not guarantee clear conditions on a given day. The unweighted mean across the monthly daily-sunshine means is 7.95 hours/day, a calendar-month summary rather than a daily forecast.

Snow

The highest monthly mean daily snowfall is recorded in February, at 2.33 mm/day. This is an average daily amount, not a monthly total; it does not establish how many days have snowfall, how deep snow becomes, whether snow cover persists, or whether conditions suit skiing. The unweighted mean of the monthly daily-snowfall means is 0.47 mm/day. This broad average likewise cannot describe snow conditions on a particular day.

Best Travel Time Guide for Xi'an, China: Ideal Seasons and Weather Insights

If lower average rainfall is your priority, January is the conditional option indicated by the lowest mean daily rainfall, 0.07 mm/day. That average does not guarantee dry days or show how frequently rain occurs, so keep plans flexible rather than treating the month as reliably rain-free. For rain preparation, note that mean daily rainfall is highest in September, at 4.06 mm/day; consider having rain-ready clothing or a backup for outdoor plans. This is a daily mean, not a monthly total or a forecast of rain on your travel dates. Visitors prioritising cooler monthly averages can look to January, when the monthly mean temperature is 0.9 °C. Pack with the possibility of day-to-day variation in mind: a monthly mean does not tell you the daytime high or the conditions on a particular outing.

For planning around average sunshine, July has the highest mean daily sunshine duration, 9.93 hours/day, while October has the lowest, 6.06 hours/day. These figures can inform outdoor sightseeing plans, but they describe sunshine duration rather than day length and cannot promise clear skies on a specific day. The highest monthly mean daily snowfall occurs in February, at 2.33 mm/day. Treat this as a limited average, not evidence of snow depth, lasting cover, or skiing conditions; it cannot tell you whether snow will affect your visit.
