SAN DIEGO, Calif. (KGTV) — San Diego summer occasions have been trending extra humid, Meteorologist Megan Parry goes in-depth To elucidate why.
Since 2013 We have seen a spike in humidity, or moisture, all by way of Southern California summer occasions, particularly alongside the coast. That is partially associated to our hotter than regular ocean water temperatures at our seashores and offshore.
The summer time of 2013 is As quickly as we entered our prolonged drought; winters have been drier Which suggests fewer storms and extra photo voltaic.
Storms are good for Greater than merely rain, they create upwelling of the ocean, appearing as a pure Washer of the ocean stirring up the water so the temperature is extra evenly distrihowevered. With fewer storms, you Even have A lot extra photo voltaicshine so the ocean is uncovered to all that warmth.
One factor has To Take in that warmth, and if the environment can’t, then the ocean Is primarily good at it. Oceans absorbing atmospheric warmth is regular, however As quickly as we see our oceans not In a place to recuperate, and the water stays warmth, that’s A drawback.
Warmer ocean temperatures, like we’ve seen since 2013, will enhance the dewpoint temperature and in a single day lows, Ensuing in a extra muggy, much less cooling influence.
2018 launched doc warmth sea floor temperatures On the Scripps Pier hitting 80.5 levels. Two yrs later in 2020, we have been shut toly as warmth at 79.5 levels.
The ocean water temperature Ought to be shut to 69 levels this time of yr Do You’d like to Take A look On the 30-yr common; Do You’d like to Take A look On The ten-yr common it’s nearer to 71 levels as a Outcome of the commons are going up.

When water temperatures are Inside the 70s, like We have been seeing the previous a quantity of summer occasions, that immediately brings moisture ranges up in what we name the dewpoint temperature.
The Southwest Monquickly is One extra set off humidity rises. Everytime You mix the monquickly with our warmth ocean, we’re getting hit twice, so It is extra humid.
It is not as humid proper now as a Outcome of We now have upwelling bringing cooler, deep ocean to the floor and the monquickly is absent. But monquickly season runs by way of September and ocean water temperatures typinamey peak On The prime of August into early September so we’ll probably get a quantity of extra stretches of humid weather earlier than The prime of summer time.
Since the oceans proceed to warmth Beset off of local weather change We will anticipate extra humid summer occasions in San Diego.
