## Key facts

| Fact | Value |
| --- | --- |
| NASA POWER climatology | 20-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2020) (API v2.9.7; LST) |
| Annual mean temperature | 25.5 °C (2 m gridded climatology; not a design percentile) |
| Highest monthly maximum | 31.9 °C (July) (monthly climatological statistic) |
| Lowest monthly minimum | 5.9 °C (January) (monthly climatological statistic) |
| Annual relative humidity | 75.7% (2 m gridded climatology) |
| Annual corrected precipitation | 3.63 mm/day (climatological daily rate) |
| Annual wind speed | 4.93 m/s (10 m gridded climatology; not a structural design wind speed) |

## Direct answer

NASA POWER's 2001–2020 climatology at the Miami, FL reference point reports an annual mean 2 m temperature of 25.5 °C and relative humidity of 75.7%. The highest monthly maximum is 31.9 °C in July, while the lowest monthly minimum is 5.9 °C in January; these are screening statistics, not code design temperatures. The point response uses LST and the 20-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2020); its annual corrected precipitation is 3.63 mm/day and annual 10 m wind speed is 4.93 m/s. Use the monthly series to screen source selection before applying project design conditions. NASA POWER is gridded climatology: verify elevation, microclimate, urban exposure, station or weather-file suitability, current code edition and the authority's required source before design use.

## Which climate inputs control the design?

1. Confirm the project jurisdiction and adopted energy-code edition.
2. Select the authoritative station and record why it applies.
3. Record heating dry-bulb percentiles and cooling dry-bulb with coincident moisture conditions.
4. Keep IP/SI units, edition, observation period and retrieval date with every value.
5. Separate climate-zone envelope requirements from HVAC sizing conditions.
