San Diego's climate turning tropical?

NOAA, Accuweather.com, Old Farmers Almanac, Weather Underground and, The Weather Channel are all reporting that in the next 30-50 years, there is a chance that San Diego will become warmer, and wetter in the summer months. This is five of the most reliable sources when it comes to weather. But there are some outside sources that also agree. This would also mean a warmer and wetter winter.

With the exception of a record breaking dry heat wave of 103 earlier this month recorded at the Lindbergh Field, for the most part, the entire summer season has been warmer than normal but also alot more humid than we've ever seen before. The ocean water temperature at Mission Beach this year reached an unprecedented 77F! Something that hasn't happened in over 32 years. 77 degrees to our visitors might not seem that warm since Florida's water temperature and the Gulf coast can and will reach the 90's, but you have to remember that the average ocean water temperature in San Diego's beaches is anywhere from 68-70.

The average high temperature for the months of July and August has steadily gone up, along with that, the rainfall totals have also increased.
40 years ago, you would be lucky if .001 of an inch of rain fell for the whole month of summer. Now if you add June+July+Aug totals, the average summer rainfall is about .025. As 50-60 years ago that average would have been less than 0.10. Some say that number will double, even triple, and that once famous chamber of commerce weather. (The typical summer night and morning low clouds and fog) San Diego was famous for will be no more. As long as the water temperature continues to climb each year, you can expect less of a sea breeze and more monsoon moisture from the four corners of the US. How long until San Diego see's it's first official tropical storm?

It would only have to warm up 7 or 8 degrees from 110 to 120 west to make San diego a offical hurricane landfall spot.

"The ocean water temperature at Mission Beach this year reached an unprecedented 77F! Something that hasn't happened in over 32 years."

How can something that hasn't happened in 32 years (meaning it happened 32 years ago) be unprecendented?

Because it's abnormal, bizarre, freakish, unheard-of. etc.. And then happening TWICE again? and only 2 degrees away for an all time record?

WELL..this is just MY 2 cents worth here but I'm tellin' ya what, there IS something strange going on this year. The flora growth is amazing.....I, nor anyone else for that matter, has seen stuff growing like it is this year, especially at my altitude, 7102'.......my trees are growing like crazy, my vegetable garden :eek: I'm growing stuff I've NEVER grown before.....it's been a LOT warmer and a HECK of a lot more HUMID this year than in years past!! Global Warming? :lol:

Since returning Saturday night, I certainly do 110% agree with that article. The humidity has been absolutely off the charts.

yea TWC said dry humidity is no more. i didnt even know they kept humidity records.

:roflmao:

BTW, I do not agree with that article. A good AFD did highlight the reason for the humidity, which is nothing more than a strong monsoonal influx combined with strong and frequent easterly waves.

I read somewhere that a hurricane HAS hit San Diego before.. a loong time ago though.

"Hit", yes. Actually landfall, no, as it remained offshore.

Recently (Chenoweth and Landsea 2005), it was re-discovered that a hurricane struck San Diego, California on October 2, 1858. Unprecedented damage was done in the city and was described as the severest gale ever felt to that date nor has it been matched or exceeded in severity since. The hurricane force winds at San Diego are the first and only documented instance of winds of this strength from a tropical cyclone in the recorded history of the state.

This summer has been predominatingly controlled by some very hot ridges of high pressure, in which, aided by the easterly flow is throwing a lot of humidity into the mix, much higher than normal in many locales in the west. In thus, with this kind of pattern setup with unusually high heat and above normal humidity values. Many, many unusual things will occur in response.

Part of the reason why water temperatures off San Diego have reached into the mid/upper 70's. You place a continual hot airmass over the region, water is gonna heat up and with the median flow in the Eastern Pacific coming from the Southeast, warmer waters are slowly traversing further north than usual.

About a week ago I visited relatives who recently moved to the san diego area and I was amazed at how warm the water was. Everyone was complaining about the air temperatures and humidity but to me it felt like a cold front had come through being from Louisiana. :lol:

And now the problem we're having right now is the marine layer has finally showed up for the fist time in weeks at the coast in San Diego BUT it's like a steam bath outside. Cloudy but high's in the mid 80's in Mission Beach. Something that just doesn't happen when the night and morning low clouds show up. This could be because the water temperature is near 80 and it's feeding off from water to the land, and that creates not much of a sea breeze. More like Hawaii trade winds. Incredible.

Incredible indeed. Nevertheless, the occasional breeze does feel refreshing - much better than the steambath yesterday.
