Frequently Asked Questions

Learn more about Weatheradar’s weather parameters, their units of measurement, and what values to pay attention to.

Atmospheric Parameters

Pressure refers to the atmospheric pressure at sea level, measured in hectopascals (hPa). Values higher than 1020 hPa often indicate clear skies, while values below 1000 hPa may signal storms or unsettled weather.

Humidity represents the percentage of water vapor in the air. Higher values (above 70%) indicate sticky or humid conditions, often preceding rain or fog.

Temperature Parameters

"Feels Like" accounts for wind chill or humidity, making it feel colder or warmer than the actual temperature. For example, wind can make a day feel colder, while high humidity makes it feel hotter.

The dew point is the temperature at which the air becomes saturated and water vapor condenses. Higher dew points (>20°) indicate humid conditions, while lower dew points (<10°) mean drier weather.

UV and Precipitation

The UV Index measures ultraviolet radiation from the sun. Values 0–2 are safe, while values 6+ require sun protection (sunscreen, shade).

Precipitation Probability is the chance of rain or snow. Values above 50% indicate a moderate likelihood, while values above 80% suggest you should carry an umbrella.

Today’s Weather in San Diego

Do you usually start your morning slow and easy, like the lazy drift of the San Antonio River? Maybe, grab your breakfast tacos — because no morning is complete without eggs, cheese, and salsa wrapped in a tortilla.

Wouldn’t you want to know if you’ll need a sun hat or an umbrella to do that? Check your weather forecast for the day as a morning routine to find out what level of SPF you need for today, or if there’s an off-chance you can go without before you start you daily routine.

What is weather like today in San Diego?

Whether you’re going for your barbacoa and enchiladas dinner with your family, or want to unwind with margaritas after a long day of work, an evening chill from the scorching sun can be a blessing.

So, before you go through planning any sort of outing, it’s a must to check your temperature, wind and any chance of rain to make sure your perfect evening out is not ruined by any whims of local weather. It does contribute to the rhythm of San Antonio—where the days flow as gently as the river, and there’s always time to share a little of the city’s magic.
