You can blame California’s wild winter for all sorts of havoc this spring and summer: moldy, leaking roofs, plagues of mosquitoes, cabin fever.
Giant, less-flavorful strawberries also deserve a spot on that list.
California produces 90% of the nation’s strawberries, which typically enjoy a growing season that starts as early as January and lasts until July. Peak season usually begins in March.
Record rain totals were reported in Alpine in San Diego County Monday, according to the National Weather Service.
There was 0.13 inches of rain reported in Alpine on Sunday, breaking the record for the day of 0.03 inches recorded in 1963.
The highest rain total recorded over the past two days in San Diego County was 0.70 inches in Lower Oat Flats. There was 0.47 inches reported in Palomar and 0.40 inches in La Jolla
El Niño is likely next winter and that could play an important role in the weather in parts of storm-weary California and the West.
But there are some important caveats and stubborn myths about this that also need to be addressed.
The atmospheric rivers may have dried up as April began, but coastal San Diego County now has to contend with a heavy marine layer bringing cool weather and drizzle.
“Basically no clearing has occurred in the San Diego coast and valleys, with only partial clearing elsewhere from the lower coastal slopes to the coast,” the National Weather Service said in its Monday afternoon update. “As a result, it was another unseasonably cool day west of the mountains.”
If there ever was a winter to check off squares on your Wild Weather Bingo card, 2023 was it.
More than 30 atmospheric river storms. 97 mph wind gusts. Destructive tidal surges. Bomb cyclones. Flash floods. Levee breaks. The Fujiwhara Effect. Snow piled more than 240 inches deep at Mammoth Pass. One of the rainiest days on record in San Francisco.
The ocean temperature off Del Mar fell to 52.25 degrees this week, the lowest reading in San Diego County waters since UC San Diego began using a buoy system in the 1970s to monitor large areas of the U.S. coastline.
UCSD’s Scripps Institution of Oceanography said near-record low readings also were recorded this week at many other stations, including off Imperial Beach and Leucadia, where the temperature was 53.5 degrees on Wednesday.
Californians gave their irrigation systems the winter off in much of 2023 thanks to above-average precipitation. As the weather warms, the U.S. EPA encourages everyone to perform a maintenance check in April as part of its “Sprinkler Spruce Up” effort.
A sprinkler spruce-up involves four steps: inspect, connect, direct, and select. Cracks in pipes can lead to costly leaks, and broken sprinkler heads can waste water and money. System maintenance can help save money and water, up to 25,000 gallons of water, and $280 over a six-month irrigation season. April is an ideal time to spruce up your irrigation system.
Because most irrigation systems run in the early morning, missing or broken sprinkler heads may go unnoticed. This can cause overflow or flooding on landscapes or waste water on hard surfaces.
Inspect your irrigation system and look for sprinkler heads that do not pop up fully or are tilted. Flag them so they can be located and repaired later. You may be able to do it yourself but call on a WaterSense-certified professional who can replace the broken sprinkler heads.
Leaks can occur at the joints between sprinklers and the piping. Leaking joints can also be caused by too much water pressure or particles in the water. Check to ensure your pressure regulator is installed properly.
Between irrigation cycles, look for water pooling on the surface of your landscaping. This could be caused by an underground leak. Check the connections inside valve boxes to make sure all the valves and other components are securely connected. If the valves cannot close completely, your system could slowly seep water even when turned off.
Irrigation water spraying on hardscapes instead of landscape plants is wasted down the stormwater drain. While your system is running, note any overspray and adjust sprinklers toward your landscaping.
The greatest waste of water in landscape irrigation comes from watering too much, too fast. Observe how water absorbs into the ground during the watering cycle. If water begins running off your landscaping or pooling, run sprinklers in multiple shorter sessions with breaks. This allows water to soak into the soil and minimizes runoff.
Instructions to help homeowners check in-ground irrigation ground systems here: “It’s Time to Start a Sprinkler Spruce-Up!” The EPA’s checklist “Find It, Flag It, Fix It: A Checklist For Your Landscape” shows how to walk through your landscape to identify problems. The checklist also provides additional irrigation and landscape tips and suggestions about when to call in an irrigation professional.
Oceanside declared a local emergency this week in hopes of getting state and possibly federal money to cover the repair costs for sinkholes, landslides, flooding and a sewage spill caused by the recent series of storms.
NOAA’s U.S. Spring Outlook indicates the abnormally wet winter will further improve drought across much of the western U.S. as the snowpack melts in the coming months. Winter precipitation, combined with recent storms, wiped out exceptional and extreme drought in California for the first time since 2020, and is expected to further improve drought conditions this spring.
Significant flooding in the western U.S., especially in California, followed another series of strong Pacific storms that battered the region in March, and piled on to an already historic snowpack.

NOAA’s U.S. Spring Outlook highlights temperature, precipitation, drought and flood predictions for April through June to help the nation prepare for potential weather and climate threats to lives and livelihoods.
“Climate change is driving both wet and dry extremes, as illustrated by NOAA’s observations and data that inform this seasonal outlook,” said NOAA Administrator Rick Spinrad, Ph.D. “Under the Bipartisan Infrastructure Law and Inflation Reduction Act, and in support of the Biden Administration’s priority to tackle the climate crisis, NOAA will invest significant resources to build a Climate-Ready Nation that gives communities tailored information about changing conditions so that residents and economies are protected.”

On March 9, NOAA forecasters declared La Niña over. The El Niño-Southern Oscillation (ENSO) is a climate pattern, based on changes in rainfall and sea surface temperatures across the equatorial Pacific Ocean, that influences temperature and precipitation around the world. La Niña occurs when ocean temperatures are cooler than normal and rainfall is reduced in the eastern to central Pacific Ocean.
“La Niña has finally ended after being in place nearly continuously for more than two years,” said Jon Gottschalck, chief of the operational prediction branch at NOAA’s Climate Prediction Center, a division of the National Weather Service. “ENSO-neutral — the transition period between El Niño and La Niña — is likely to continue into the early summer with elevated chances of El Niño developing thereafter. ENSO-neutral is factored into NOAA’s Spring Outlook.”
Moderate to exceptional drought coverage across the U.S. is at its lowest since August 2020 and is likely to continue improving, or end entirely, across much of California and the Great Basin. The spring wet season is expected to improve drought conditions across parts of the northern and central Plains. Current drought conditions in Florida are expected to improve or go away during the next three months.
Areas of extreme to exceptional drought across parts of the southern High Plains are likely to persist through the spring season, with drought also expected to develop into parts of New Mexico. Across parts of the Northwest U.S. and northern Rockies, drought conditions are also expected to continue. Drought may develop into parts of Washington state.
Above-average temperatures are favored for much of the southern and eastern half of the U.S. For April through June, the greatest chance for above-average temperatures exists from the southern High Plains eastward to Florida, and northward along the East Coast. Above-average temperatures are also likely for Hawaii and northern parts of Alaska. Below-average temperatures are predicted for the central Great Basin and the northern Plains.

Parts of central and southern California that were still reeling from heavy snowfall earlier this month received yet another powerful atmospheric river which exited the region on March 15. Flooding, landslides, power outages, and evacuations are among the many impacts residents faced from the recent storm. The above graphic depicts most of the state receiving between 300-600% of normal precipitation over the last seven days. — USDA Water and Climate Update
NOAA forecasters predict above-average precipitation this spring across the Great Lakes, Ohio Valley, and into parts of the mid-Atlantic and Northeast. Below-average precipitation is most likely for the Southwest and parts of the Pacific Northwest.
