Hanford, CA – A stretch of warm October weather is expected to bring temperatures near 90 degrees to California's central San Joaquin Valley this weekend before a noticeable cooling trend arrives early next week. Sunshine will dominate the Hanford area through Sunday, with Saturday expected to be the warmest day of the forecast period. By Tuesday, afternoon temperatures could fall into the mid 70s as a slight chance of rain develops, marking a significant shift from the weekend's dry, summerlike conditions.
According to the National Weather Service in Hanford, temperatures are expected to reach approximately 84 degrees Thursday, Oct. 15, before climbing to 88 Friday and 90 Saturday, Oct. 17. Sunday remains warm with a projected high near 88 degrees, but a gradual cooling trend begins Monday as temperatures fall to around 82. By Tuesday, Oct. 20, highs could reach only 74 degrees, representing a 16 degree decline from Saturday's projected peak.
Saturday Heat Peaks Near 90 Degrees The warmest conditions are expected Saturday afternoon, when sunny skies and light winds will allow temperatures to reach approximately 90 degrees in Hanford. Calm morning winds are forecast to become westerly around 5 mph during the afternoon, offering limited relief from the warmth.

Despite the warm afternoons, overnight temperatures will remain considerably cooler. Saturday night temperatures are expected to fall to around 57 degrees, providing relief before another sunny afternoon Sunday.
Warm Weekend Conditions Affect Valley Activities The stretch of sunny, warm weather will be noticeable across Hanford and nearby Kings County communities, including Lemoore and surrounding agricultural areas. Residents attending outdoor events, working in fields or spending extended periods outside should prepare for afternoon temperatures approaching 90 degrees.
Motorists traveling along State Route 198, State Route 43 and nearby U.S. Highway 99 corridors should anticipate warm daytime conditions, particularly during longer trips. The supplied forecast does not identify any weather related highway closures or significant travel disruptions during the weekend.

Cooler Air and Rain Chances Arrive Next Week Sunday will remain sunny and warm, with temperatures reaching approximately 88 degrees before falling to around 55 Sunday night. Monday brings additional cooling, with highs near 82 degrees and northwest winds around 5 mph.

Wednesday, Oct. 21, continues the cooler pattern, with temperatures reaching approximately 73 degrees and a 20% chance of rain. The forecast does not specify rainfall totals, and the limited precipitation probabilities suggest uncertainty about whether measurable rain will develop in Hanford.
