Will California get cooler temperatures this fall? What NOAA, Old Farmer's Almanac predict
The Old Farmer's Almanac predicts seasonal weather conditions every year for the United States, and its new 2025 autumn weather forecast shows vast swaths of the country, including California, could experience a warm and dry fall season. The National Oceanic and Atmospheric Administration is also predicting above-normal temperatures nationwide for the autumn months.
From the Central Valley to the Southern Coast, fall 2025 is shaping up to be dry and steamy for California, especially in September, when scattered thunderstorms may briefly interrupt the heat. While Northern California may see some regional showers by October, Southern California is expected to remain largely parched.
Here's what to know about predicted conditions in California this fall from the Almanac and the National Weather Service's Climate Prediction Center:
What is the Old Farmer's Almanac prediction for fall 2025 in California?
The Old Farmer's Almanac fall 2025 weather forecast for California predicts a warm start to the season in Northern California, with scattered thunderstorms expected in early and mid-September. As the season progresses into October, the weather is expected to cool down, accompanied by regional showers later in the month.
Here are the key highlights:
September: Warm with intermittent thunderstorms.
October: Average temperature around 76°F, which is near normal. Rainfall is forecasted at 2.5 inches, about 2 inches below normal
The Old Farmer's Almanac fall 2025 forecast for Southern California anticipates a warmer-than-normal autumn with below-average rainfall.
September: Temperature: Warmer than normal. Precipitation: Below average.
October: Temperature: Still above average, though slightly cooler than September. Precipitation: Remains below normal.
The Almanac suggests a 'steamy' start to fall, with above-normal hurricane activity nationally, though direct impacts on Southern California are unlikely.
What is the National Weather Service's fall forecast?
These predictions are essentially in line with those of the National Weather Service's Climate Prediction Center. The weather agency's three-month outlook for September, October, and November 2025 indicates that the probability of above-normal temperatures for most of California ranges from 33% to 50%. Chances for above-normal temperatures are greater in eastern California.
The agency's rain forecast for the same three-month period indicates "equal chances" of above-normal, below-normal, and near-normal precipitation totals for California.
Staying cool when it's hot
The National Weather Service recommends that people who are highly sensitive to heat stay hydrated, keep windows open at night, and wear light clothing.
Here are some more heat precautions:
Immediately move to a cooler place and rest at the first signs of heat illness
Go outside during the cooler parts of the day
Take a lot of breaks when working outdoors
What's the difference between heat exhaustion and heat stroke?
People experiencing heat exhaustion may feel dizzy, thirsty, sweat heavily, experience nausea, and feel weak. They may also experience cramps, clammy skin, and a weak pulse.
Someone experiencing heat stroke can have a body temperature above 103 degrees, hot and red skin, a fast pulse, and a headache. They also might be confused or have lost consciousness. It's essential to call 911 right away if someone has heat stroke.

As Texas Floods Swept Campers Away, A Top Official Didn't Show Up. Another Was Asleep.
Texas officials involved in the deadly Kerr County flood response testified to lawmakers Thursday about the many failures made during the tragedy. In the early morning of July 4, the Guadalupe River rose around 26 feet, causing flash floods that killed more than 100 people, including 28 children. More remain missing. As the disaster unfolded, the county's top official was nowhere to be found. Another official said he was sick and asleep. William B. Thomas IV, the county's emergency management coordinator, testified that he was sleeping off an illness as floodwaters rose. 'I stayed in bed throughout July 3 and did not participate in the regularly scheduled 10 a.m. and 3 p.m. Texas Emergency Management Coordination Center coordination calls,' Thomas testified. Thomas said his supervisors knew he was off that day, and said he slept most of July 3. At around 2 p.m., Thomas said he went back to sleep until his wife woke him at 5:30 a.m. on July 4 to alert him about the floods. Part of Thomas' job was to then alert the public. He testified that he reported to the sheriff's office, but decided not to issue an alert to cell phones because the National Weather Service already did. 'To those who ask, what would you have done differently? The honest answer is that, based on the data we had at the time, there was no clear indicator that a catastrophic flood was imminent,' Thomas said. 'The situation evolved faster than anyone could have predicted.' Thomas' response is similar to one given by Kerr County Judge Rob Kelly, the county's most senior elected official. 'We didn't know this flood was coming,' Kelly said at a news conference after the flood. As county judge, Kelly serves as the head of emergency management. On the day of the tragedy, Kelly was at his second home in Lake Travis and didn't wake up until 4:20 a.m. on July 4 after getting calls and texts from law enforcement officials. 'We received no alerts suggesting an extreme weather event was imminent,' Kelly testified Thursday. Kerr County lacks a local flood warning system, despite being prone to flooding. Kelly previously said that residents felt a warning system was too expensive to implement, The New York Times reported. Among those who died were girls at a Christian summer camp. Dick Eastland, the 70-year-old owner and director of Camp Mystic, was among those who died while trying to save the lives of his campers. He had been warning of floods and the need for warning systems for years. Lt. Gov. Dan Patrick (R) tore into Kelly during Thursday's hearing. 'We didn't just lose people, we didn't know where people were,' Patrick told Kelly. 'And you weren't here. I asked where you were for the press conference that night, you weren't here.' Patrick said it was Kelly's responsibility to direct the emergency response. 'I just want to set the record straight: Everyone was here that day working their ass off, and you were nowhere to be found.' The hearing is ongoing and expected to last throughout the day.

Canadian Wildfire Smoke Prompts Air Quality Alerts Across the Great Lakes Region
Smoke from Canadian wildfires set off multiple air quality alerts on Thursday across the Midwest and the Canadian prairies, stretching eastward to Toronto. 'There's a pretty large swath of smoke actually over the central part of the country right now, and you can see that coming down from central Canada,' said Dave Radell, a meteorologist with the National Weather Service in New York. The smoke is expected to remain over the northern and central Plains for the next couple of days, he said, adding that there was a chance it could drift toward the East Coast during the later part of the weekend and into early next week. In Canada, where fires have scorched millions of acres, air quality alerts were issued for multiple provinces, including parts of Manitoba, Ontario and Saskatchewan. Every air quality monitor in Minnesota is reporting red or unhealthy conditions for everyone, said Matt Taraldsen, supervisory meteorologist at Minnesota Pollution Control Agency.

Sunshine and perfect summer weather is settling into Hamilton and most of southern Ontario for the August long weekend. However, a special air quality statement has been issued Thursday on the heels of a just-cancelled heat warning. Forest fires in the Prairies are blowing east and pushing the city's Air Quality Health Index into the high risk danger zone Thursday. The smoke is causing or expected to cause poor air quality and reduced visibility before dropping to a moderate risk on Friday and low risk Friday night, according to Environment Canada . The National Weather Service has forecast a mix of sun and cloud Thursday with a high of 21 C, feeling like 26 with humidex. Thursday is the worst day for smoke pollution, which will vary considerably from hour to hour. The service warns residents to take precautions.
