Solar elevation and azimuth over the course of February 2022. The black lines are lines of constant solar elevation (the angle of the sun above the horizon, in degrees). The background color fills indicate the azimuth (the compass bearing) of the sun. The lightly tinted areas at the boundaries of the cardinal compass points indicate the implied intermediate directions (northeast, southeast, southwest, and northwest).

Moon

The figure below presents a compact representation of key lunar data for February 2022. 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.

Humidity

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 Los Angeles is essentially constant during February, remaining around 0% throughout.

For reference, on 4 August, the muggiest day of the year, there are muggy conditions 7% of the time, while on 10 November, the least muggy day of the year, there are muggy conditions 0% of the time.

Wind

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 metres 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 Los Angeles is essentially constant during February, remaining within 0.4 kilometres per hour of 12.5 kilometres per hour throughout.

For reference, on 31 December, the windiest day of the year, the daily average wind speed is 14.0 kilometres per hour, while on 13 August, the calmest day of the year, the daily average wind speed is 8.4 kilometres per hour.

The wind direction in Los Angeles during February is predominantly out of the north from 1 February to 23 February and the west from 23 February to 28 February.

The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions, excluding hours in which the mean wind speed is less than 1.6 km/h. The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).

Water Temperature

Los Angeles 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 Los Angeles is essentially constant during February, remaining around 15°C throughout.

The lowest average surface water temperature during February is 15°C on 16 February.

Growing Season

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 (≥ 0°C) in the year (the calendar year in the Northern Hemisphere, or from 1 July until 30 June in the Southern Hemisphere).

Temperatures in Los Angeles 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 10°C and a cap of 30°C.

The average accumulated growing degree days in Los Angeles are increasing during February, increasing by 122°C, from 134°C to 256°C, over the course of the month.

Solar Energy

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 Los Angeles is increasing during February, rising by 1.0 kWh, from 3.7 kWh to 4.7 kWh, over the course of the month.

Topography

For the purposes of this report, the geographical coordinates of Los Angeles are 34.052 deg. latitude, -118.244 deg. longitude, and 88 m elevation.

The topography within 3 kilometres of Los Angeles contains only modest variations in elevation, with a maximum elevation change of 122 metres and an average elevation above sea level of 95 metres. Within 16 kilometres contains only modest variations in elevation (793 metres). Within 80 kilometres contains large variations in elevation (3,067 metres).

The area within 3 kilometres of Los Angeles is covered by artificial surfaces (100%), within 16 kilometres by artificial surfaces (94%), and within 80 kilometres by shrubs (37%) and water (28%).

Data Sources

This report illustrates the typical weather in Los Angeles, based on a statistical analysis of historical hourly weather reports and model reconstructions from 1 January 1980 to 31 December 2016.

Temperature and Dew Point

There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Los Angeles.

For each station, the records are corrected for the elevation difference between that station and Los Angeles 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 Los Angeles is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Los Angeles and a given station.

The stations contributing to this reconstruction are:

• Los Angeles / USC Campus Downtown (KCQT, 81%, 5.4 km, southwest, -34 m elevation change)
• Burbank Bob Hope Airport (KBUR, 11%, 20 km, northwest, 148 m elevation change)
• Mount Wilson (KMWS, 0.6%, 26 km, northeast, 1,651 m elevation change)
• Fullerton Municipal Airport (KFUL, 7%, 32 km, southeast, -59 m elevation change)

To get a sense of how much these sources agree with each other, you can view a comparison of Los Angeles and the stations that contribute to our estimates of its temperature history and climate. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.

Other Data

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.

Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database .

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.
