Spring, if the numbers from the past year hold, but only if your home is ready and priced right. We don’t have a month-by-month series for Discovery Bay alone. For Contra Costa County as a whole, single-family homes that closed from February through June 2026 sold in a median of 12 to 13 days, and the county median price peaked at $935,000 in May (C.A.R., monthly home sales and price reports, checked September 25, 2026).
Discovery Bay moves slower than that county number. Redfin shows a median of 34 days on market here in August 2026, with 36.5% of sold homes taking a price cut first (Redfin, Discovery Bay housing market page, August 2026, checked September 24, 2026). So the month helps. The first price helps more.
What does a year of county data show?
A clear rhythm: slow in winter, quick in spring, stretching out again by late summer. These are C.A.R.’s figures for existing single-family homes in all of Contra Costa County, not Discovery Bay. Each month comes from that month’s C.A.R. release, checked September 25, 2026.
| Month closed | County median price | Median days on market | Months of supply |
|---|---|---|---|
| Sept. 2025 | $869,000 | 22 | 2.9 |
| Oct. 2025 | $860,000 | 19 | 2.4 |
| Nov. 2025 | $889,000 | 22 | 2.3 |
| Dec. 2025 | $839,500 | 21 | 1.9 |
| Jan. 2026 | $802,000 | 29 | 3.6 |
| Feb. 2026 | $819,000 | 13 | 3.0 |
| Mar. 2026 | $870,000 | 13 | 2.4 |
| Apr. 2026 | $875,000 | 12 | 2.6 |
| May 2026 | $935,000 | 13 | 2.3 |
| June 2026 | $920,000 | 13 | 2.3 |
| July 2026 | $875,000 | 15 | 2.6 |
| Aug. 2026 | $875,000 | 20 | 2.7 |
“Months of supply” is C.A.R.’s Unsold Inventory Index, the number of months it would take to sell every listing at that month’s pace. A lower number means fewer homes competing with yours.
Two cautions. C.A.R. counts a sale in the month it closes, so a May closing usually means a listing that went live in March or April. And this is one year for a whole county. It’s a pattern worth knowing, not a promise about next spring.
Why is Discovery Bay slower than the county?
We can’t prove why from the data, and the two sources measure different things. C.A.R.’s county figures cover single-family homes only. Redfin’s Discovery Bay figures cover every home type, and only 53 homes sold here in August 2026 (Redfin, August 2026). A handful of slow deep-water listings can move that median a lot.
What the Discovery Bay numbers do say: homes sold for 97.7% of list price on average in August 2026, and only 25.0% sold over list (same Redfin page). Buyers here had time to compare. A listing that starts high in the “right” month can still sit.
Should I sell a waterfront home in summer?
Maybe, but check what’s happening on the water first. The warm months are when docks, boats and lagoon views are in use. They’re also when algae advisories have hit. The state posted a “danger” advisory for harmful algal blooms in Discovery Bay on July 9, 2024 (State Water Resources Control Board press release, July 9, 2024, checked September 25, 2026), and as of September 25, 2026 the Town’s site shows a “caution” advisory for Willow Lake.
Look up the current advisory for your stretch of water on the state’s HAB portal at mywaterquality.ca.gov/habs before you set a date. Ask a real estate attorney what you need to disclose about past advisories. Don’t guess.
What should I get ready before a spring listing?
Start in winter. The county data says the quick months begin in February, and Discovery Bay homes have a few local items to line up:
- The water side. Dock, lift, slope rock and anything sun and water have worn down. Reclamation District 800 gives free rip rap rock, delivered to the driveway, to owners on deep water or Willow Lake for the slope behind the home (RD 800, Rip Rap Rock page, checked September 25, 2026). The owner places it or hires someone to.
- Permits. RD 800 reviews construction on and around levees and slopes (Town of Discovery Bay, Reclamation District 800 page, checked September 25, 2026). Pull your records for any dock or slope work now.
- Your tax bill. RD 800’s new Maintenance and Capital Assessment starts in fiscal year 2026-27 (RD 800, board minutes, November 6, 2025). If your home is inside the district, buyers will see a new line. Have the bill ready to share.
- The HOA packet, if you’re in one of the nine associations the Town lists (Town of Discovery Bay, Home Owners Associations page, checked September 25, 2026). Order it early.
Is fall or winter a bad time to sell here?
Not if you price for it. In the county data, January 2026 was the slowest month at 29 days and the lowest median at $802,000. But December 2025 had the thinnest supply of the year, 1.9 months, so fewer homes were competing for the buyers who were out. If you need to move in winter, you can. Just expect a smaller crowd and price off the most recent sales, not last spring’s.
Questions people also ask
What month do homes sell fastest in Contra Costa County?
In C.A.R.’s figures for Contra Costa County single-family homes, April 2026 was fastest at a median of 12 days, with February, March, May and June at 13. January 2026 was slowest at 29 days. That’s county-wide data by closing month, checked September 25, 2026, not Discovery Bay alone, and one year of it.
How long does it take to sell a house in Discovery Bay?
Redfin shows a median of 34 days on market for Discovery Bay homes sold in August 2026, checked September 24, 2026. That’s slower than the Contra Costa County single-family median of 20 days the same month, per C.A.R. The two sources count different home types, and only 53 Discovery Bay homes sold that month.
Is spring the best time to sell a Discovery Bay home?
Spring was the quickest stretch county-wide in 2026: Contra Costa single-family homes closing from February through June sold in a median of 12 to 13 days, per C.A.R. But in August 2026, 36.5% of Discovery Bay homes sold had a price cut first, per Redfin. A realistic first price matters more than the month.
Should I wait until next spring to sell?
It depends on your plans, not just the calendar. County data shows spring 2026 moved fastest, but waiting has costs: more months of payments, HOA dues and bills, and no one can promise next spring’s prices. Price your home off recent sales of homes like yours, then decide whether waiting is worth it to you.
