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 at Bechar, 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, remaining a virtually constant 0% 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 at Bechar experiences significant seasonal variation over the course of the year.

The windier part of the year lasts for 4.4 months, from March 8 to July 19, with average wind speeds of more than 8.9 miles per hour. The windiest month of the year at Bechar is May, with an average hourly wind speed of 10.3 miles per hour.

The calmer time of year lasts for 7.6 months, from July 19 to March 8. The calmest month of the year at Bechar is December, with an average hourly wind speed of 7.4 miles per hour.

The predominant average hourly wind direction at Bechar varies throughout the year.

The wind is most often from the south for 5.7 months, from May 11 to November 3, with a peak percentage of 40% on July 30. The wind is most often from the north for 6.3 months, from November 3 to May 11, with a peak percentage of 42% on January 1.

To characterize how pleasant the weather is at Bechar 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 Bechar for general outdoor tourist activities are from mid March to mid May and from early October to early November, with a peak score in the second 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 times of year to visit Bechar for hot-weather activities are from early May to late June and from late August to early October, with a peak score in the first week of June.

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).

While it does not do so every year, freezing temperatures are seen at Bechar over some winters. The day least likely to be in the growing season is January 8, with a 52% chance.

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 at Bechar should appear around January 28, only rarely appearing before January 19 or after February 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 4.2 months, from April 12 to August 18, with an average daily incident shortwave energy per square meter above 7.2 kWh. The brightest month of the year at Bechar is June, with an average of 8.0 kWh.

The darker period of the year lasts for 3.1 months, from October 31 to February 3, with an average daily incident shortwave energy per square meter below 4.4 kWh. The darkest month of the year at Bechar is December, with an average of 3.5 kWh.
