• Inland Empire: Expect high temperatures reaching 100-105°F (38-40°C), with lows around 70-75°F (21-24°C). This area will experience the most significant temperature increase.
• Los Angeles County: Highs are predicted to be in the 85-95°F (29-35°C) range, with lows in the mid-60s to low 70s (°F) (18-21°C). Coastal areas will experience milder temperatures.

The peak of the heat wave is anticipated to be Saturday, with temperatures gradually decreasing on Sunday. This differs significantly from the average temperatures for this time of year, which typically range from the low 70s to mid-80s (°F) (21-29°C) depending on the location. Staying informed about the hourly temperature forecast is crucial for planning outdoor activities.

Health and Safety Precautions

Protecting yourself from heat-related illnesses during this Southern California heat wave is paramount. Heat stroke and heat exhaustion are serious risks, particularly for vulnerable populations.

• Hydration is key: Drink plenty of water throughout the day, even before you feel thirsty. Avoid sugary drinks and excessive alcohol.
• Limit strenuous activity: Avoid intense physical activity during the hottest parts of the day (typically between 10 a.m. and 4 p.m.). If you must be outside, take frequent breaks in the shade.
• Dress appropriately: Wear light-colored, loose-fitting clothing to reflect the sun's rays.
• Sun protection: Use sunscreen with an SPF of 30 or higher, wear a hat, and seek shade whenever possible.
• Check on vulnerable populations: Check on elderly neighbors, friends, and family members, especially those living alone. Young children are also at increased risk.
• Stay cool indoors: Use fans and air conditioning to keep your home cool. Take cool showers or baths.
• Emergency resources: In case of a heat-related emergency, call 911 immediately. Locate your nearest cooling center by contacting your local city services.

Potential Impact on Outdoor Activities

This weekend's Southern California heat wave will undoubtedly impact outdoor plans. Consider these modifications:

• Outdoor activities: Adjust hiking plans to start earlier in the morning or choose less strenuous trails. Opt for shaded areas whenever possible. Consider postponing outdoor activities entirely to a cooler day.
• Alternative indoor activities: Explore indoor options like visiting museums, movie theaters, or shopping malls. Plan for some indoor fun this weekend.
• Outdoor events: If attending outdoor events, take extra precautions to stay hydrated, wear appropriate clothing, and seek shade frequently. Be aware that some events might be cancelled or postponed due to the heat.

Staying Safe at the Beach

Even though the coastal areas will experience milder temperatures than inland regions, beachgoers need to remain vigilant.

• Sun protection: Apply sunscreen liberally and frequently, wear a hat, and seek shade under umbrellas or beach canopies.
• Hydration: Bring plenty of water and drink frequently, even while swimming. Dehydration can occur quickly in the sun.
• Rip currents: Be aware of rip currents and heed warnings from lifeguards.

Hiking in the Heat

Hiking during a heat wave requires extra caution.

• Early starts: Begin your hike early in the morning before temperatures climb.
• Hydration: Carry ample water and electrolytes. Don't underestimate how much you'll need.
• Trail conditions: Check trail conditions beforehand and choose a shorter, less strenuous hike if necessary.
• Heatstroke symptoms: Be aware of the symptoms of heatstroke (high body temperature, confusion, rapid pulse, etc.) and seek help immediately if you experience them.
