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 Yosemite Lakes, 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 in Yosemite Lakes experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 3.5 months, from April 4 to July 21, with average wind speeds of more than 5.1 miles per hour. The windiest month of the year in Yosemite Lakes is June, with an average hourly wind speed of 5.6 miles per hour.

The calmer time of year lasts for 8.4 months, from July 21 to April 4. The calmest month of the year in Yosemite Lakes is November, with an average hourly wind speed of 4.5 miles per hour.

The predominant average hourly wind direction in Yosemite Lakes varies throughout the year.

The wind is most often from the west for 7.2 months, from March 11 to October 16, with a peak percentage of 58% on June 20. The wind is most often from the east for 4.8 months, from October 16 to March 11, with a peak percentage of 50% on January 1.

To characterize how pleasant the weather is in Yosemite Lakes 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 time of year to visit Yosemite Lakes for general outdoor tourist activities is from early June to late September, with a peak score in the third week of August.

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 Yosemite Lakes for hot-weather activities is from late June to mid August, with a peak score in the third 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 Yosemite Lakes typically lasts for 9.2 months (280 days), from around February 25 to around December 1, rarely starting before January 13 or after April 1, and rarely ending before November 11 or after December 23.

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 Yosemite Lakes should appear around February 23, only rarely appearing before February 10 or after March 10.

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.

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

Temperature and Dew Point

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

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

The stations contributing to this reconstruction are:

• Madera Municipal Airport (KMAE, 48%, 23 mi, southwest, -1,014 ft elevation change)
• Fresno Air Terminal Airport (KFAT, 41%, 29 mi, south, -935 ft elevation change)
• Mammoth Lakes Airport (KMMH, 6%, 59 mi, northeast, 5,860 ft elevation change)
• Bridgeport Sonora Junction (KBAN, 5%, 82 mi, north, 5,482 ft elevation change)

To get a sense of how much these sources agree with each other, you can view a comparison of Yosemite Lakes 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.

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.
