Climate Chart of Atlanta, USA

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

Climate overview

Temperature

Monthly mean temperatures range from a low of 6.0 °C in January to a high of 25.5 °C in July. These are averages for each month, not daytime highs, so they describe the broad temperature profile rather than the warmth visitors can expect at a particular hour. Across the calendar months, the unweighted mean of monthly means is 16.4 °C; it is not a day-weighted annual average.

Rain

Mean daily rainfall is highest in February at 5.28 mm/day and lowest in October at 3.00 mm/day. The unweighted mean across the monthly means is 4.08 mm/day. These figures describe average daily amounts, not monthly totals, and the lower mean does not guarantee rain-free days or indicate how often rain occurs. For planning, they are useful as relative monthly context rather than a day-by-day forecast.

Sunshine

Average daily sunshine reaches its highest monthly mean in June, at 11.03 hours/day, and its lowest in December, at 5.60 hours/day. The unweighted mean of the monthly figures is 8.63 hours/day. These are sunshine-duration averages, not measures of daylight length, and actual conditions can differ from the monthly pattern; use them as a broad guide when planning outdoor time.

Snow

Mean daily snowfall is highest in February, at 0.77 mm/day; the unweighted mean across the monthly means is 0.12 mm/day. These are recorded average amounts, not evidence of how many days have snow, its depth or persistence, or whether conditions suit snow sports. The figures therefore provide a limited view of snowfall rather than a measure of likely snow cover during a visit.

Best Travel Time Guide for Atlanta, USA: Ideal Seasons and Weather Insights

If cooler monthly-average conditions are your priority, January is the relevant reference point, with a mean temperature of 6.0 °C. Treat this as a monthly average rather than a promise about daytime temperatures or any specific visit; check a current forecast closer to departure. For visitors prioritising lower average rainfall, October is the conditional option: its mean daily rainfall is 3.00 mm/day. Rain preparation is also worth considering for February, when the mean daily amount is 5.28 mm/day. Neither figure establishes the chance of rain on a given day, so bring adaptable plans rather than relying on a dry spell.

For outdoor sightseeing guided by average sunshine duration, June records 11.03 hours/day per day, while December records 5.60 hours/day per day. Sunshine duration is not daylight length and cannot guarantee clear conditions, so use these contrasts as a broad planning aid, not a forecast. Temperature, rainfall and sunshine point to different criteria; the averages do not establish one universally best time to visit. Snowfall averages also have limits for trip planning: the highest monthly mean daily amount is 0.77 mm/day in February. This does not tell you whether snow will fall during a visit, how deep it may be, or whether it will remain on the ground; check current local conditions if snowfall matters to your plans.
