Forecasters are calling this one of the strongest El Niño winters on record — and if you own acreage, a well, or a septic system in Placer County, now is the time to get ahead of it.

If you've heard chatter about a "Super El Niño" this year, it's not just weather-nerd hype. NOAA's Climate Prediction Center has put the odds of a very strong El Niño event above 90% for fall and winter 2026–27 — up from 63% in June and 81% in July. There's even a real possibility this becomes the strongest El Niño on record, going back to 1950.
For us here in Placer County, that matters. NOAA's outlook concentrates the heaviest El Niño rain signal right over coastal and Northern California, with the wettest stretch expected to ramp up later in the season — peaking January through March of 2027 rather than this fall. Translation: we likely have a bit of runway before the real soaking begins, which is exactly the window you want for home prep.
What Makes This El Niño Different
A "Super El Niño" refers to unusually warm sea surface temperatures in the equatorial Pacific, which reshape the jet stream and tend to funnel wetter, stormier weather into California. As of mid-August, sea surface temperature anomalies in the key monitoring region were already running well above the threshold for a super event, and forecasters have only grown more confident since.
What that has historically meant for California: a wetter-than-average winter overall, a higher chance of atmospheric river storms stacking up back-to-back, and a heavier Sierra snowpack. It's the mirror image of the dry La Niña pattern we've seen in recent years — and after a relatively quiet 2025–26 season, a lot of properties in our area simply haven't been tested by a truly wet winter in a while.
I show a lot of acreage and rural properties out here, and the ones that struggle in a wet winter are almost always the same culprits: a driveway culvert that was never cleaned out, a septic field that sits low, or gutters that haven't seen a ladder since the last owner. None of that is expensive to fix in October. It's a very different story in January.
From the lending side, this is also a good time to double check your homeowners policy details with your lender if you're escrowing insurance, especially if you're near a floodplain or seasonal creek. If a storm does cause damage, having your policy and documentation in order ahead of time makes any insurance or loan-related follow-up much smoother.
Prepping Your Home for a Wet Winter
Whether you're on a quarter-acre in Rocklin or ten acres out in Loomis, here's where I'd focus your time and budget before the storms ramp up:
Clean and inspect the roof and gutters. A single storm can expose a bad seal or a clogged downspout you didn't know you had. Clear debris, check flashing around chimneys and vents, and make sure water is being directed at least several feet away from the foundation.
Walk your grading and drainage. Look for low spots near the house, driveway, or outbuildings where water pools rather than moves. On acreage, this is also the time to clear culverts, ditches, and any drainage swales — a blocked culvert under a rural driveway is one of the most common (and most avoidable) storm-season failures I see.
Have your well and septic checked. Heavy, saturated ground can affect septic drain field performance and, in low-lying areas, can push surface water toward wellheads. If it's been a few years since your last inspection, a wet winter is not the time to find out something's marginal.
Look up, not just down. Take stock of large trees near the house, barn, or power lines. Saturated soil plus wind is exactly what brings trees down in an El Niño winter. Dead limbs or leaning trees are worth addressing now rather than after the ground softens.
Check your insurance coverage now. Flood damage typically isn't covered under a standard homeowners policy. If you're in a low-lying area or near a seasonal creek, it's worth a conversation with your agent before storm season, not during it.
A strong El Niño winter isn't something to fear — it's something to plan for. The properties that come through it best are almost always the ones where basic maintenance happened in October, not January.
The Bottom Line
We likely have some time before the heaviest rain arrives — but "some time" is exactly the point. A weekend spent clearing gutters and culverts now can save you a much more expensive and stressful repair come January. If you're not sure where to start, or you're weighing whether a property you're considering buying is set up to handle a wet winter, I'm always happy to walk it with you.
