For reference, the year's highest daily chance of a wet day is 30% on June 26, and its lowest chance is 2% on January 16.

Rainfall

To show variation within the season and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day.

Over the course of the spring in Santa Cruz, the length of the day is very rapidly increasing. From the start to the end of the season, the length of the day increases by 2 hours, 54 minutes, implying an average daily increase of 1 minute, 56 seconds, and weekly increase of 13 minutes, 31 seconds.

The shortest day of the spring is September 1, with 11 hours, 24 minutes of daylight and the longest day is November 30, with 14 hours, 18 minutes of daylight.

The latest sunrise of the spring in Santa Cruz is 7:53 AM on September 8 and the earliest sunrise is 1 hour, 28 minutes earlier at 6:25 AM on November 30.

The earliest sunset is 6:27 PM on September 1 and the latest sunset is 2 hours, 16 minutes later at 8:43 PM on November 30.

Daylight saving time (DST) ends at 1:00 AM on September 8, 2024, shifting sunrise and sunset to be an hour earlier.

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 Santa Cruz is essentially constant during the spring, remaining around 0% throughout.

For reference, on January 28, the muggiest day of the year, there are muggy conditions 1% of the time, while on May 17, the least muggy day of the year, there are muggy conditions 0% 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 Santa Cruz is increasing during the spring, increasing from 5.0 miles per hour to 6.4 miles per hour over the course of the season.

For reference, on December 14, the windiest day of the year, the daily average wind speed is 6.6 miles per hour, while on May 3, the calmest day of the year, the daily average wind speed is 4.9 miles per hour.

The wind direction in Santa Cruz during the spring is predominantly out of the south from September 1 to October 15 and the west from October 15 to November 30.

The spring in Santa Cruz is more likely than not fully outside of the growing season, with the chance that a given day is in the growing season increasing from 84% to 100% over the course of the season.

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 Santa Cruz are rapidly increasing during the spring, increasing by 682°F, from 125°F to 807°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 Santa Cruz is very rapidly increasing during the spring, rising by 4.6 kWh, from 4.2 kWh to 8.8 kWh, over the course of the season.
