A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in New California varies throughout the year.

The wetter season lasts 4.7 months, from March 26 to August 17, with a greater than 30% chance of a given day being a wet day. The chance of a wet day peaks at 41% on May 25.

The drier season lasts 7.3 months, from August 17 to March 26. The smallest chance of a wet day is 19% on January 27.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 41% on May 25.

Snowfall

We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.

As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. New California experiences some seasonal variation in monthly liquid-equivalent snowfall.

The snowy period of the year lasts for 4.3 months, from November 23 to April 1, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around February 12, with an average total liquid-equivalent accumulation of 0.4 inches.

The snowless period of the year lasts for 7.7 months, from April 1 to November 23. The least snow falls around July 21, with an average total liquid-equivalent accumulation of 0.0 inches.

The transitions to and from daylight saving time are indicated by the 'DST' labels.

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.

New California experiences significant seasonal variation in the perceived humidity.

The muggier period of the year lasts for 3.6 months, from May 29 to September 17, during which time the comfort level is muggy, oppressive, or miserable at least 11% of the time. The muggiest day of the year is July 26, with muggy conditions 45% of the time.

The least muggy day of the year is January 28, when muggy conditions are essentially unheard of.

Wind

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 New California experiences significant seasonal variation over the course of the year.

The windier part of the year lasts for 7.1 months, from October 13 to May 16, with average wind speeds of more than 9.4 miles per hour. The windiest day of the year is January 15, with an average hourly wind speed of 12.0 miles per hour.

Best Time of Year to Visit

To characterize how pleasant the weather is in New California 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 New California for general outdoor tourist activities is from mid June to mid September, with a peak score in the second week of August.

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.

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 (≥ 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 New California typically lasts for 5.8 months (176 days), from around April 22 to around October 15, rarely starting before April 4 or after May 10, and rarely ending before September 25 or after November 5.

Data Sources

This report illustrates the typical weather in New California, 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 3 weather stations near enough to contribute to our estimation of the temperature and dew point in New California.

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

The stations contributing to this reconstruction are: Union County Airport (43%, 12 kilometers, northwest); Ohio State University Airport (30%, 16 kilometers, southeast); and Delaware Municipal Airport - Jim Moore Field (27%, 17 kilometers, northeast).

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.

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.
