KTLA 5 Weather Forecast: Southern California Warm-Up and Potential Rain Outlook - Jan 13, 2026

Current Weather Conditions

• ☀️ The current weather in Southern California is beautiful with clear skies and no marine layer, attributed to an offshore flow making it nice and warm.
• 🏖️ Temperatures are pleasant, with beach areas reaching 75 degrees Fahrenheit this afternoon, Woodland Hills and Yuba Linda at 85 degrees, and Chino at 78 degrees.
• 📉 Expect temperatures to drop quickly after sunset, leading to cooler mornings, with Van Nuys at 61 degrees, Los Alamitos at 52, Camarillo at 53, and Temecula/Anza at 48 degrees.

Extended Forecast and Temperature Trends

• 📈 Temperatures are expected to peak on Wednesday and Thursday before gradually cooling down.
• 🥶 By next week, specifically Thursday and Friday, temperatures are predicted to be below average.
• 💧 There is a hope for more rain, as the water year doesn't end until around March or April, despite recent rainfall in December and some in January.

Atmospheric Patterns and Wind

• 🌬️ An offshore flow is currently in place, contributing to the warm and dry conditions.
• ⬆️ A dome of high pressure is expected to amplify and push north, which will continue to bring offshore flow through Thursday.
• 🚧 By Sunday, January 18th, this pattern will evolve into a blocking ridge, potentially diverting weather systems away from Southern California to the east.
• 💨 While not as strong as yesterday, northeasterly winds are still present, extending from Pacific Palisades across the Malibu coastline up to Oxnard, and are expected to diminish by tomorrow late afternoon.
• 🌡️ Relative humidity will remain low due to the dry offshore flow, despite winds not being exceptionally strong in most areas.

Regional Forecast Highlights

• ☀️ San Gabriel Valley: Sunny and 83 degrees on Wednesday, with temperatures in the upper 70s by Sunday and Monday.
• 💨 San Fernando Valley: Low 80s through Sunday, with windy conditions on Wednesday and Thursday, becoming calmer by the weekend.
