Want Bay Area sun under $1 million? Look east of the hills

Clayton Valley, on Concord's east side under Mount Diablo, gets about 81 percent of its possible sunshine in a typical year. Its typical home costs about $590,000, according to Houseberry's Clayton Valley page. On the other side of the hills, the Outer Sunset gets about 71 percent and its typical home costs about $1.69 million.

Clayton Valley is one of 118 Bay Area neighborhoods that are both sunny and priced under $1 million, by Houseberry's count. Concord, Antioch and Pittsburg hold 47 of them. San Francisco and San Mateo County hold none.

How we counted

Every Houseberry neighborhood page carries a weather block built from PRISM's 30-year climate normals (1991 to 2020), sampled across the neighborhood's own boundary. Those averages roll up into a sun score from 1 to 5. A score of 3.8 or better puts a neighborhood in our Sunny or Very sunny band, which works out to roughly 79 percent of possible sunshine or more. These are long-run averages, not a forecast.

Prices are Houseberry's typical home price from MLS sales, as of October 2026. We counted only neighborhoods in the five counties our price data covers (San Francisco, San Mateo, Santa Clara, Alameda and Contra Costa), with at least 8 sales in the past 12 months and high confidence in the climate data. That leaves 695 neighborhoods, and 207 of them have a typical price under $1 million.

Sun is not what you are paying for

This was the finding that surprised us. If buyers paid extra for sunshine, sunny neighborhoods would cluster at the top of the price range. They do not. Of the neighborhoods under $1 million, 57 percent rate sunny. Between $1 million and $1.5 million, 56 percent. Between $1.5 million and $2.5 million, 59 percent. Above $2.5 million it rises to 66 percent.

Bay Area buyers pay for commute, schools and proximity to San Francisco and Silicon Valley. Sunshine comes along for free in the places that are far from the fog, which are mostly the places that are far from the jobs. If sun is near the top of your list, that is good news. It is one of the cheapest things to buy in the region.

The six very sunny neighborhoods under $1 million

Six neighborhoods reach a sun score of 4.2, the highest we see under $1 million. Four are in Concord.

1. Clayton Valley, Concord: about $590,000, July high about 85°F

2. Olive, Concord: about $674,000, July high about 85°F

3. Kirkwood, Concord: about $681,000, July high about 84°F

4. Clayton Valley Highlands, Concord: about $707,000, July high about 85°F

5. Dougherty Rd / Amador Valley Blvd, Dublin: about $926,000, July high about 87°F

6. Crow Canyon, San Ramon: about $959,000, July high about 86°F

They are ordered by price. Every one of them gets about 81 percent of its possible sunshine on its Houseberry page.

Clayton Valley Highlands ranks second of 42 Concord neighborhoods for sunshine. Olive ranks fifth and Kirkwood tenth. In Concord, the sun barely varies. What varies is the house.

Concord is the value play

Concord has 17 neighborhoods on the list, and most sit between about $590,000 and $820,000. Concord's two BART stations run straight to downtown San Francisco. The summers are hot but not Brentwood-hot, with July highs in the mid 80s.

We think Concord is the best answer on this list for a buyer who wants sun and a train. Antioch and Pittsburg are cheaper, but they sit farther out on the line, with Antioch at the end of it, and run a few degrees hotter in August. You can compare all 42 Concord neighborhoods on Houseberry's Concord ranking.

Antioch and Pittsburg: the most sun per dollar

Antioch has 18 neighborhoods on the list and Pittsburg 12. Sunset Dr in Antioch has a typical price of about $551,000. Empire Ave is about $690,000, and Somersville in Pittsburg about $655,000. Every one rates Very sunny.

The trade-off is July. Empire Ave averages about 89°F in July, and summer days on its page run from 58° to 87°F. The Delta breeze helps at night, but these are air-conditioning neighborhoods. We compared that summer heat across the region in our heat-wave post on the 24-degree gap between Bay Area neighborhoods.

San Jose has the most, and they run milder

San Jose has 23 sunny neighborhoods under $1 million, more than any other city. They run cooler than the Contra Costa list, with July highs around 81°F. Alexander has a typical price of about $607,000. Loma Verde is about $901,000 and scores 4.0 on sun.

For a buyer working in the South Bay, this is the shorter commute and the milder summer.

The mild-summer option: Hayward and Fremont

If 86°F sounds like too much, look at the bayside cities. Hayward has six sunny neighborhoods under $1 million and Fremont three, with July highs in the mid to high 70s. Tennyson-Alquire in Hayward gets about 79 percent of its possible sunshine, a July high of about 75°F, and a typical price of about $822,000. Centerville in Fremont is about $884,000 with a July high around 78°F.

You give up about two percentage points of sunshine and get summers that are ten degrees cooler. For a lot of people that is the better deal.

Where the sun runs out

San Francisco has five neighborhoods under $1 million in our data and none rates sunny. Across the 48 San Francisco neighborhoods we measured, the median sun score is 3.3. San Mateo County has seven neighborhoods under $1 million and none of them is sunny either.

Oakland is the other gap. It has 19 neighborhoods under $1 million that miss the sunny band, the most of any city, and Richmond and Hayward have 12 each. Morning fog and afternoon wind off the Bay reach those blocks before they reach Concord.

Questions buyers ask

Is the sun score the same as hot weather? No. It measures how much sunshine a place gets and how often clouds and fog block it. Hayward's sunny neighborhoods are sunny and mild. Antioch's are sunny and hot.

Do these numbers change year to year? The climate normals are 30-year averages, so they move slowly. Prices update monthly on each Houseberry neighborhood page.

Which county has the most? Contra Costa, with 75 of the 118. Santa Clara has 26 and Alameda 17.
