We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The chance that a given day will be muggy in General San Martín is essentially constant during July, remaining around 0% throughout.

The lowest chance of a muggy day during July is 0% on July 17.

For reference, on February 8, the muggiest day of the year, there are muggy conditions 50% of the time, while on July 17, the least muggy day of the year, there are muggy conditions 0% of the time.

Temperature and Dew Point

There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in General San Martín.

For each station, the records are corrected for the elevation difference between that station and General San Martín according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

The estimated value at General San Martín is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between General San Martín and a given station.

The stations contributing to this reconstruction are:

  • Buenos Aires (SABA, 76%, 3.0 mi, east, -3 ft elevation change)
  • Don Torcuato Aerodrome (SADD, 24%, 6 mi, northwest, -69 ft elevation change)

To get a sense of how much these sources agree with each other, you can view a comparison of General San Martín and the stations that contribute to our estimates of its temperature history and climate. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands.

We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
