The figure below presents a compact representation of key lunar data for 2024. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon 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.

The perceived humidity level in Mā‘īn, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, staying within 4% of 4% throughout.

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 Mā‘īn experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 9.5 months, from November 11 to August 28, with average wind speeds of more than 6.8 miles per hour. The windiest month of the year in Mā‘īn is February, with an average hourly wind speed of 7.5 miles per hour.

The calmer time of year lasts for 2.5 months, from August 28 to November 11. The calmest month of the year in Mā‘īn is October, with an average hourly wind speed of 6.2 miles per hour.

The predominant average hourly wind direction in Mā‘īn varies throughout the year.

The wind is most often from the west for 8.4 months, from January 7 to September 18 and for 2.4 weeks, from October 21 to November 7, with a peak percentage of 73% on July 25. The wind is most often from the north for 1.1 months, from September 18 to October 21, with a peak percentage of 47% on September 24. The wind is most often from the east for 2.0 months, from November 7 to January 7, with a peak percentage of 33% on January 1.

To characterize how pleasant the weather is in Mā‘īn 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 Mā‘īn for general outdoor tourist activities are from early May to early July and from late August to late October, with a peak score in the last week of September.

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 Mā‘īn for hot-weather activities is from mid June to mid September, with a peak score in the last week of July.

Methodology

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).

The growing season in Mā‘īn typically lasts for 11 months (330 days), from around January 31 to around December 26, rarely starting after March 9, or ending before November 28.

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 Mā‘īn should appear around February 20, only rarely appearing before February 6 or after March 14.

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 extreme seasonal variation over the course of the year.

The brighter period of the year lasts for 3.6 months, from May 4 to August 24, with an average daily incident shortwave energy per square meter above 7.5 kWh. The brightest month of the year in Mā‘īn is June, with an average of 8.6 kWh.

The darker period of the year lasts for 3.2 months, from November 4 to February 10, with an average daily incident shortwave energy per square meter below 4.3 kWh. The darkest month of the year in Mā‘īn is December, with an average of 3.2 kWh.

For the purposes of this report, the geographical coordinates of Mā‘īn are 31.680 deg latitude, 35.732 deg longitude, and 2,772 ft elevation.

The topography within 2 miles of Mā‘īn contains very significant variations in elevation, with a maximum elevation change of 889 feet and an average elevation above sea level of 2,586 feet. Within 10 miles contains very significant variations in elevation (4,291 feet). Within 50 miles also contains extreme variations in elevation (5,663 feet).

The area within 2 miles of Mā‘īn is covered by cropland (46%), sparse vegetation (25%), and grassland (11%), within 10 miles by sparse vegetation (45%) and bare soil (34%), and within 50 miles by bare soil (60%) and sparse vegetation (15%).
