Climate Chart of Jackson, USA

Climate overview

Temperature

The coolest monthly mean is 8.2 °C in January, while the warmest is 27.4 °C in July. These are averages for each month, not daytime maximum temperatures, so they do not describe the full range visitors might experience within a day. Across the calendar months, the unweighted mean of the monthly temperature means is 18.6 °C. This summary gives broad annual context, but it is not a day-weighted average or a substitute for conditions in a particular month.

Rain

Mean daily rainfall is highest in April, at 5.68 mm/day, and lowest in September, at 2.32 mm/day. The lower monthly mean can help identify an option for visitors prioritising less average rainfall, but it does not guarantee dry days or indicate how often rain occurs. The unweighted mean of the calendar-month daily rainfall means is 3.88 mm/day. These are daily averages, not monthly rainfall totals, so they should be read as a broad comparison rather than a measure of rain on any particular date.

Sunshine

Mean daily sunshine reaches its highest value in June, at 11.45 hours/day, and its lowest in December, at 6.08 hours/day. These averages can inform planning for daylight outdoor activities, but sunshine duration is not the same as day length and does not guarantee clear conditions. The unweighted mean across the calendar-month sunshine means is 8.94 hours/day per day. It provides a general reference for the year, while the monthly extrema better show how sunshine duration varies by month.

Snow

Mean daily snowfall is highest in January, at 0.78 mm/day. This is a small recorded daily mean, but it does not establish the number of snowy days, snow depth, or whether snow cover or suitable skiing conditions occur. The unweighted mean of the calendar-month daily snowfall means is 0.08 mm/day. As with the monthly peak, this daily average cannot indicate how snowfall is distributed among individual days.
