Wettest 14 Months in Los Angeles in 134 Years

With over 45 inches of rain reported, the 14 months (424 days) ending February 22, 2024, have been the wettest in Downtown Los Angeles in 134 years.

To put this in perspective, this is more than three times the amount Los Angeles would see in a “normal” year.

The wettest 14 months on record for Los Angeles occurred during late December 1888 to early February 1890, when about 47 inches of rain was recorded.

Rainy Season Trail Running on the Backbone Trail

The Backbone Trail between Encinal Canyon and Mishe Mokwa is one of the must-do sections of the 68-mile trail. Engineered to be multi-use, this exceptionally scenic stretch of the Backbone Trail is popular with riders, hikers, and runners alike.

It’s also a pretty good place for a trail run after rainy weather like we’ve had this February. Although the parking lot at the Encinal Trailhead was quite wet this morning, the  Backbone Trail was in decent shape most of the way to the Mishe Mokwa trailhead. There were a few muddy and wet spots, but it was generally easy to work around them. And I didn’t have to change my shoes before driving home.

The out & back run worked out to about 21-miles, with a surprisingly moderate gain/loss of about 2500′. The weather and visibility were excellent. Striking rock formations and the Channel Islands could be seen from one side of Etz Meloy Mtwy fire road, and snow on Alamo Mountain and other Ventura County peaks from the other side.

On the way back, as I was working up the long hill on the northwest side of Triunfo Lookout, a descending mountain biker commented that a large group of bikers were at “the corner.” The overlook at this prominent switchback has a wide-ranging view of Mishe Mokwa, Boney Mountain, and Sandstone Peak, and some prefer to turn around here. This variation is about 3.5 miles shorter (round-trip) than dropping down into the canyon and going all the way to Mishe Mokwa.

East Las Virgenes Canyon After a Seventh Day of Rain

East Las Virgenes Canyon After a Seventh Day of Rain

A very wet East Las Virgenes Canyon and Trail on February 8, 2024,  following seven days of rain. This was by far the wettest start to February in Los Angeles since recordkeeping began in July 1877.

Running to the Temescal Canyon Cascade From the Top of Reseda (Two Ways)

Temescal Canyon Cascade

The Temescal Canyon “waterfall” is an immensely popular cascade, most often accessed from Temescal Gateway Park using the Temescal Canyon Trail. Judging from the number of people on the trail, a loop incorporating the Temescal Canyon and Temescal Ridge Trails is also very popular.

Even though many refer to it as a waterfall, it’s not a dramatic river-wide fall, such as Nevada Fall in Yosemite. Picture a Japanese garden with a gurgling little stream, cascading down through rocks into a pool, surrounded by an artistic arrangement of plants and trees. There’s even the requisite bridge to complete the composition. It would be meditative if it were not so popular.

Over the past few weeks, I’ve run from the Top of Reseda (Marvin Braude Mulholland Gateway Park) to the Temescal Canyon Cascade two ways — a 15-mile out-and-back and a 21-mile loop.

The out-and-back route from the Top of Reseda was one of those “I’ll just go a little bit farther” runs. It had rained the day before and the NWS forecast called for a chance of showers in the morning and then showers likely in the afternoon.

With the weather unsettled, I didn’t have a particular plan in mind. When I started the run, it looked like it might rain at any time, so I decided to run to Temescal Peak, and then play it by ear from there. Once on Temescal Peak, the weather seemed to be holding, so I continued to Temescal Lookout. From the Lookout, Green Peak was just a “little bit further,” and in a few minutes, I was standing on top.

I continued to be drawn down Temescal Ridge in this fashion, and before I knew it was at the junction of the Temescal Ridge and Temescal Canyon Trails. From there, it was only a half-mile down to the cascade.

Two weeks later, I was back at the Top of Reseda. It had rained an inch and a half in Downtown Los Angeles a couple of days before, and a well-advertised multi-day rain event was forecast to begin the following day.

The previous weekend, a friend and I had climbed/run to Sandstone Peak from Wendy Drive. Temps in the sun reached into the 80s, and maybe I talked too much and ate and drank too little. On the way back, I hit the wall near the turn onto the Upper Sycamore Trail.

This morning, I had no idea how my legs were going to feel. My loosely defined plan was to run out the Rogers Road segment of the Backbone Trail from the Top of Reseda and see. If the legs held up, I’d continue to Will Rogers State Historic Park. If not, maybe I’d do Goat Peak or something else.

The temperature was in the 40s most of the way down to Will Rogers. With the cool weather, it seemed my running was back to normal. From Will Rogers, I headed over to Rivas Canyon, where I found Sierra Club volunteers hard at work on the Rivas Canyon Trail. This enjoyable trail links Will Rogers to Temescal Canyon and is a key part of the loop.

Once down in Temescal Canyon, there was a constant stream of hikers going up the Temescal Canyon Trail to the cascade. With the recent rain and good weather, the cascade had more water and more people than on the run in January. A large group rested near the bridge, and hikers hustled and bustled up and down the trail. The little cascade gurgled and burbled in the morning sun, glistening bubbles popping up beneath the plunging stream and then disappearing as they wandered downstream.

Soon, I was chugging up the trail toward its junction with the Temescal Ridge Trail, retracing my steps from two weeks before.

Spring Wildflowers in December?

The paintbrush above, and the following Spring-blooming wildflowers were photographed on December 14,2023, on a trail run from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve. With the exception of the black mustard, the wildflowers were found along a half-mile stretch of dirt road connecting upper Las Virgenes and Cheeseboro Canyons.

The false Spring was the result of rain from Tropical Storm Hilary in August, an extended period of wetter than normal weather, and somewhat warmer Fall temperatures. The Water Year that ended September 30, 2023 was the seventh wettest on record for Los Angeles and Calendar Year 2023 was the sixth wettest.
