Moon Rise, Set & Phases
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.
Naranjal experiences extreme seasonal variation in the perceived humidity.
The muggier period of the year lasts for 7.5 months, from September 28 to May 13, during which time the comfort level is muggy, oppressive, or miserable at least 27% of the time. The muggiest day of the year is February 9, with muggy conditions 86% of the time.
The least muggy day of the year is July 22, with muggy conditions 7% of the time.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.
The average hourly wind speed in Naranjal does not vary significantly over the course of the year, remaining within 0.3 miles per hour of 2.4 miles per hour throughout.
Average Wind Speed
The predominant average hourly wind direction in Naranjal varies throughout the year.
The wind is most often from the east for 2.0 weeks, from January 1 to January 15; for 3.3 months, from February 19 to May 29; and for 1.1 months, from July 27 to September 1, with a peak percentage of 36% on March 17. The wind is most often from the north for 1.1 months, from January 15 to February 19; for 1.9 months, from May 29 to July 27; and for 1.4 weeks, from December 22 to January 1, with a peak percentage of 37% on February 12. The wind is most often from the south for 3.7 months, from September 1 to December 22, with a peak percentage of 38% on October 4.
Best Time of Year to Visit
To characterize how pleasant the weather is in Naranjal throughout the year, we compute two travel scores.
The tourism score favors clear, rainless days with perceived temperatures between 65°F and 80°F. Based on this score, the best times of year to visit Naranjal for general outdoor tourist activities are from mid March to early June and from early August to late November, with a peak score in the last week of April.
The beach/pool score favors clear, rainless days with perceived temperatures between 75°F and 90°F. Based on this score, the best time of year to visit Naranjal for hot-weather activities is from early November to early April, with a peak score in the second week of March.
For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation. Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed.
Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies.
Our precipitation score, which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0.04 inches of precipitation or more.
Our tourism temperature score is 0 for perceived temperatures below 50°F, rising linearly to 9 for 65°F, to 10 for 75°F, falling linearly to 9 for 80°F, and to 1 for 90°F or hotter.
Our beach/pool temperature score is 0 for perceived temperatures below 65°F, rising linearly to 9 for 75°F, to 10 for 82°F, falling linearly to 9 for 90°F, and to 1 for 100°F or hotter.
Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).
While it does not do so every year, freezing temperatures are seen in Naranjal over some winters. The day least likely to be in the growing season is July 11, with a 65% chance.
Time Spent in Various Temperature Bands and the Growing Season
frigid 15°F freezing 32°F very cold 45°F cold 55°F cool 65°F comfortable 75°F warm 85°F hot 95°F sweltering
Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.
Based on growing degree days alone, the first spring blooms in Naranjal should appear around July 9, only rarely appearing before July 7 or after July 13.

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.
The average daily incident shortwave solar energy experiences significant seasonal variation over the course of the year.
The brighter period of the year lasts for 3.5 months, from October 30 to February 12, with an average daily incident shortwave energy per square meter above 6.4 kWh. The brightest day of the year is December 12, with an average of 7.2 kWh.
The darker period of the year lasts for 2.9 months, from May 10 to August 6, with an average daily incident shortwave energy per square meter below 4.1 kWh. The darkest day of the year is June 25, with an average of 3.3 kWh.

This report illustrates the typical weather in Naranjal, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Naranjal.
For each station, the records are corrected for the elevation difference between that station and Naranjal 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 Naranjal is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Naranjal and a given station.
The stations contributing to this reconstruction are: Guaraní International Airport (43%, 67 kilometers, northeast); Cataratas del Iguazú International Airport (39%, 76 kilometers, east); and Villarrica (18%, 127 kilometers, west).
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.
