Annual Temperature Patterns
A climate baseline for a city that experiences every season.

Research Question
What are Atlanta’s average temperatures throughout the year?
Technical Summary
The annual climatological temperature regime establishes a seasonally varying thermal boundary condition for Atmos Oasis. Analysis of the 1991–2020 NOAA normals for Atlanta Hartsfield International Airport reveals pronounced summer heating demand, measurable winter exposure, and a substantial shoulder-season transition.
Atlanta is not simply “hot.” Temperatures change dramatically across the year, so the station must be designed for summer heat, winter cold, and everything in between.
Research Findings
Seasonal climatology
The NOAA 1991–2020 station record gives an annual mean daily maximum of 73.2°F and mean daily minimum of 54.1°F. July has the highest normal daily maximum at 90.1°F; January has the lowest normal daily minimum at 35.6°F.
In plain English: These values describe what is typical, not the worst weather the station could encounter.
Thermal design envelope
Monthly averages describe a climatological baseline, not an equipment rating. Extremes, radiant exposure, humidity, and equipment enclosure temperature must be evaluated separately.
In plain English: A station designed only for the monthly average may fail on the hottest or coldest days.
Shoulder-season flexibility
Spring and autumn conditions cross heating and cooling comfort thresholds, motivating variable operating modes instead of a single fixed temperature response.
In plain English: The station should adapt automatically as the season changes.

Engineering Significance
These observations establish environmental constraints for the solar-powered Atmos Oasis adaptive public climate station. Design choices remain hypotheses until subsystem capacity, safety and field performance are validated.
- Use the full seasonal profile when comparing cooling/heating loads.
- Design adjustable rather than always-on climate control.
- Add sensor-based operating thresholds and validate against extreme conditions.
Design Implications & Next Step
Quantify design-day extremes, solar exposure, humidity and thermal comfort criteria before specifying system capacity.
Verified temperature normals; operating thresholds still require engineering validation.
Test Your Understanding
Why can’t a system be sized using July’s average temperature alone?
Reveal the explanation
An average is not a heat-wave extreme. The design must also allow for humidity, sun exposure, hot equipment surfaces and unusual weather.
Sources & Research Notes
Weather figures refer to the Atlanta Hartsfield International Airport station, not every neighborhood in metro Atlanta. Sources and data limitations are recorded to support reproducibility.
