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 Oakland experiences mild seasonal variation over the course of the year. The windier part of the year lasts for 5. The windiest month of the year in Oakland is June , with an average hourly wind speed of 9.
The calmer time of year lasts for 6. The calmest month of the year in Oakland is October , with an average hourly wind speed of 7. The wind is most often from the west for 9. The wind is most often from the north for 2. Oakland is located near a large body of water e.
This section reports on the wide-area average surface temperature of that water. The average water temperature experiences some seasonal variation over the course of the year.
The time of year with warmer water lasts for 2. The time of year with cooler water lasts for 5. To characterize how pleasant the weather is in Oakland throughout the year, we compute two travel scores. Based on this score, the best time of year to visit Oakland for general outdoor tourist activities is from late June to early October , with a peak score in the third week of August. Based on this score, the best time of year to visit Oakland for hot-weather activities is from mid August to late September , with a peak score in the first week of September.
For each hour between AM and PM of each day in the analysis period to , 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. Temperatures in Oakland 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.
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 experiences extreme seasonal variation over the course of the year.
The brighter period of the year lasts for 3. The brightest month of the year in Oakland is June , with an average of 8. The darker period of the year lasts for 3. The darkest month of the year in Oakland is December , with an average of 2. For the purposes of this report, the geographical coordinates of Oakland are The topography within 2 miles of Oakland contains only modest variations in elevation, with a maximum elevation change of feet and an average elevation above sea level of 30 feet.
Within 10 miles contains only modest variations in elevation 1, feet. Within 50 miles contains very significant variations in elevation 4, feet. This report illustrates the typical weather in Oakland, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, to December 31, There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Oakland.
For each station, the records are corrected for the elevation difference between that station and Oakland 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 Oakland is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Oakland and a given station. To get a sense of how much these sources agree with each other, you can view a comparison of Oakland 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.
All data relating to the Sun's position e. 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 kilometer grid.
