The figure below presents a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. The horizontal axis is the day of the year and the vertical axis is the hour of the day. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. The black isolines are contours of constant solar elevation.

The figure below presents a compact representation of key lunar data for the spring of 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. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon.

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 Anajatuba is essentially constant during the spring, remaining within 2% of 92% throughout.

The lowest chance of a muggy day during the spring is 90% on October 3.

For reference, on February 25, the muggiest day of the year, there are muggy conditions 100% of the time, while on October 2, the least muggy day of the year, there are muggy conditions 90% 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 Anajatuba is gradually increasing during the spring, increasing from 4.7 miles per hour to 5.7 miles per hour over the course of the season.

For reference, on October 24, the windiest day of the year, the daily average wind speed is 6.0 miles per hour, while on April 23, the calmest day of the year, the daily average wind speed is 2.8 miles per hour.

The highest daily average wind speed during the spring is 6.0 miles per hour on October 24.

The wind direction in Anajatuba during the spring is predominantly out of the east from September 1 to October 16 and the north from October 16 to November 30.

Anajatuba is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.

The average surface water temperature in Anajatuba is essentially constant during the spring, remaining within 1°F of 81°F throughout.

The lowest average surface water temperature during the spring is 80°F on September 20.

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).

Temperatures in Anajatuba are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year.

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.

The average accumulated growing degree days in Anajatuba are very rapidly increasing during the spring, increasing by 2,954°F, from 1,903°F to 4,856°F, over the course of the season.

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 in Anajatuba is gradually decreasing during the spring, falling by 0.5 kWh, from 6.7 kWh to 6.2 kWh, over the course of the season.
