Yes, it is quite variable. The difference between Escondido and Oceanside is sometimes 20*F. It depends on the wind direction and speed. I've heard

it goes up an average of 1 degree for every mile you go inland (up to a certain limit, of course). But even that probably varies.

I've seen a very large temp difference here in Central Ca as well.

Drove to the coast one summer day, Gilroy, which is in a inland coastal valley north of San Jose was 105f, But the drive just 5 miles west over the coastal range found fog and temps of 57f in Wastonville right on the coast.

We experienced a 20F difference yesterday when we started work in Coronado right on the bay/coast, and finished in Alpine 20 miles inland.

A couple of weeks back I crossed the Golden Gate Bridge in fog and 59F, and 24 miles north, in Novato, Marin County, the temperature reached 96F -- that's 1.5 degrees per mile!

The difference in temperature is a topic of discussion for Angelenos. People compare weather conditions in the same way one discusses travel conditions. But the radical difference is not just measured in miles but also topography. For example Leo Carrillo beach in Malibu can easily be 20 degrees cooler than nearby Arroyo Sequit which is only 5 miles away but over 1000' difference in elevation. And the Woodland Hills section of Los Angeles averages 96F\ 35.5C in July compared to Santa Monica's 76F\ 24.4C; only 10 miles separates the two regions. The Getty Museum in West Los Angeles looks out over the Pacific Ocean 5 miles away yet is often 15 degrees F warmer than the pier. During "Santa Ana" events in Autumn the reverse can

be truth. I live in the foothills of Los Angeles where the ocean is a distance view yet the difference between the beaches of El Segundo and my area [approximately 12 miles away] is generally 20 degrees during summer.

This is remarkable climate diversity rarely seen anywhere else in the world.

Here, in Portugal, we experience similar temperature differences between coastal and inland locations.

Today, for instance, in southern Portugal, at the coast we had 28C - 30C and some places 5 Km inland it was nearing 40C.

I LIVE the Difference!! :D

Zone 10a at best after 2007 AND 2013, on SW facing hill, 1 1/2 miles from coast in Oceanside, CA. 30-98 degrees, and 45-80deg. about 95% of the time.

I do some experiments and learning in my garden with palms so you don't have to experience the pain! Look at my old threads to find various observations and tips!

Hmm.

Land at LAX, which is on the beach.

Drive in your top-down rental car, bound for Palm Springs! Put on your souvenir sunglasses, remove the Fanny Pack of Doom, and relax. A lovely ride lies ahead!

On July 4, it's about 65 F at the airport; by the time you're going past the shimmering towers of downtown LA, soaring like the Emerald City, it's in the mid-80s.

Further and further you go, down the 10 freeway, and, by the time you get to Covina, or maybe Pomona, you put the top up, and put on the air as the temps hit the 90s F. Ah! Cold air from the vents. Bliss.

Onward! To San Bernardino! It's about a hundred degrees. Put your hand on the car window, and feel the heat through it. Open the window, for a quick blast of hot air.

Past Redlands, Yucaipa, Beaumont. Here it's a bit cooler as the altitude increases, as I-10 snakes through the foothills of the mighty mountains. If it's June, you might see snow on the highest mountaintops . . . .

Finally, in Banning, the mountains watch your back and front, as you go down the hill into one of the biggest tawny-colored sand piles on Earth. Thousands of windmills on the nearby mountainsides. Indian bingo. Shows! Win! Lose! Ostentation! Too much! Except that the desert still dwarfs it all.

Get to Palm Springs, and it's almost too hot to touch the car's window. The thermometer on the bank says it's 125 F.

120 miles, more or less. I think. I'm sure someone will correct me if I'm wrong.
