What is the average temp in san diego

There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in San Diego. For each station, the records are corrected for the elevation difference between that station and San Diego 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 San Diego is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between San Diego and a given station.

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

Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database. Time zones for airports and weather stations are provided by AskGeo.

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.

The percentage of days in which various types of precipitation are observed, excluding trace quantities: rain alone, snow alone, and mixed both rain and snow fell in the same day. The average rainfall solid line accumulated over the course of a sliding day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands.

Late summer and early autumn are typically the hottest times of the year with an average high of 78 degrees in August and 77 degrees in September. Snow and ice are rare in the wintertime, and typically occur only in the mountainous areas with higher elevations and much more inland from the coast. San Diego receives its fair share of marine layer clouds, most often between May and August, which cause cool temperatures, cloudy weather, and dense fog in the morning.

Marine layer conditions linger until the heat of the sun becomes strong enough to evaporate the cloud cover. The cool, cloudy conditions often last into the afternoon or sometimes even all day. Although confusing to tourists, newcomers, and out-of-the-region visitors, this makes October the fire season for the San Diego area and the rest of Southern California due to low precipitation and sporadic heat waves that the average monthly temperatures do not immediately show. For example, the months with the highest record temperatures are September at degrees, and October at degrees.
