Is Your Conejo Valley or Simi Valley Property Ready for the 2026 Super El Niño?

This winter is shaping up to be one of the strongest El Niño events Southern California has seen since NOAA started tracking these patterns back in 1950. Climate scientists are already calling it a “Super El Niño,” and the Climate Prediction Center currently gives the region a very high chance of a historic wet season, with the heaviest rain expected to hit between January and March. At Gonzalez Landscaping & Tree Service, we work across Conejo Valley every day, and we know exactly what heavy rain does to yards, hillsides, and trees that haven't been prepped for it. Here is what you need to know, and what we're doing to help homeowners in Thousand Oaks, Westlake Village, Agoura Hills, Oak Park, Newbury Park, Moorpark, and Simi Valley get ready before the first storm hits.

What Makes This El Niño Different

Forecasters aren't just predicting a wetter than normal winter this year, they're tracking ocean temperatures that could make this the strongest El Niño on record. Southern California sits right in the path of the heaviest rain totals expected this season. The tricky part isn't just the total rainfall, it's how it tends to arrive: in short, intense bursts rather than steady, gentle rain. That pattern is exactly what turns a dry hillside into a mudslide risk or a clogged drain into a flooded yard almost overnight.

Why Local Hillsides and Yards Are at Risk

Conejo Valley has been here before. Heavy El Niño rain has triggered debris flows and evacuation warnings across the county in past seasons, and some hillside communities are still dealing with the aftermath of storms from years ago. Every time we get called out after a storm, the damage almost always traces back to one of two things: a yard drain that couldn't keep up with the volume of water, or a tree limb that gave out once the soil around its roots turned to mud. Both are preventable events if you get ahead of them.

Three Ways Gonzalez Landscaping & Tree Service Helps You Get Ready

At Gonzalez Landscaping & Tree Service we take pride in offering solutions to our community in Conejo Valley, Simi Valley and Malibu. Get a free property inspection and estimate this season, focused on the two areas that matter most before a Super El Niño winter hits your backyard.

1. Yard Drain Cleaning

We'll check your yard drains, French drains, and downspouts for the leaves, dirt, and debris that build up over a dry summer. If a clogged drain isn't cleared before the rain starts, water backs up fast once storms turn steady, and it doesn't just sit in your yard, it pushes toward your foundation, seeps into crawl spaces, and can flood a garage or a ground floor room in a matter of hours. Waiting until the storm is already here to check your drains is waiting too long.

2. Tree Trimming

We'll remove deadwood, thin out heavy or overgrown canopies, and take a close look at any tree that's leaning, damaged, or growing too close to your roofline or power lines. Once heavy rain saturates the soil, a tree's roots lose their grip fast, and a strong gust on top of that soaked ground is often all it takes for a weak limb or an entire tree to come down on a roof, a car, or a power line, increasing the cost in repairs and insurance; or even risking the life of your family and neighbors. Waiting until after the first storm to deal with a leaning tree usually means dealing with the damage instead.

3. Slope Maintenance & Erosion Control

For properties on a hillside or a sloped lot, which are common throughout Conejo Valley and Simi Valley, we check for loose soil, bare patches, and drainage paths that could give way under sustained rain. Conejo Valley has seen real debris flows and evacuation warnings in past El Niño seasons, and it doesn't take an extreme storm for a saturated, unstable slope to slide, undermine a retaining wall, or send mud and debris toward a home below. Addressing erosion risk now, while the ground is still dry, is far easier than dealing with a slope failure once the rain has already soaked in.

Frequently Asked Questions

When does the 2026 El Niño season peak in Southern California?

The heaviest rain from this year's El Niño is expected to peak between January and March, though Southern California could see an earlier start to the rainy season this fall.

Why does tree trimming matter before a wet winter?

Saturated soil combined with strong wind is one of the most common reasons trees or heavy limbs come down during a storm. Removing deadwood and thinning overgrown canopies now lowers that risk before the ground gets soft.

What happens if my yard drains are clogged when the rain hits?

Clogged or undersized drains are one of the fastest ways a yard floods during a storm, since the water has nowhere to go but back toward your home's foundation.

What can happen if I wait until the rain starts to clear my drains?

Once steady rain sets in, a clogged drain backs up fast, and that water doesn't have anywhere to go but toward your home. Clearing drains before the season starts is far easier than dealing with a flooded yard or garage mid storm.

Why is slope maintenance part of El Niño prep?

Saturated soil loses stability, and a hillside or sloped lot that looked fine all summer can become an erosion or slope failure risk once heavy rain sets in. Conejo Valley has seen debris flows in past El Niño seasons, so checking slopes and drainage paths now matters.

How much notice do I need to book a pre storm inspection?

The sooner the better. Once storms start rolling through, schedules fill up quickly, and inspections that would normally take a day or two to arrange can take much longer once everyone is trying to book at the same time.
