Seasonal Safety Guide for Seniors on California’s Central Coast

Living on California’s Central Coast comes with many blessings — mild temperatures, stunning scenery, and a close-knit community. But for older adults in San Luis Obispo County, each season also brings its own set of health and safety considerations. From summer heat waves and wildfire smoke to rainy-season fall risks and the mood shifts of shorter winter days, staying ahead of seasonal changes is one of the most important things seniors and their families can do to protect health and independence.

This guide is designed to help seniors in Paso Robles, Atascadero, Arroyo Grande, Santa Maria, and throughout SLO County navigate the year with confidence — and to make sure families know about the local resources available to keep their loved ones safe.

Why Seasonal Changes Hit Seniors Harder

As we age, our bodies become less efficient at adapting to environmental changes. Older adults do not adjust as well as younger people when confronted with abrupt temperature changes, and they are more likely to have chronic medical conditions that alter their physiological response to heat or cold. [1] Additionally, many seniors take prescription medications that affect the body’s ability to regulate temperature or sweat — making both summer heat and winter cold more dangerous than they might appear. [2]

Understanding these vulnerabilities is the first step toward building a safer, healthier routine for every season.

Summer: Heat Safety on the Central Coast

While San Luis Obispo County enjoys a famously mild climate, summer temperatures — especially inland in areas like Paso Robles and Atascadero — can climb well above 90°F. Older adults (65+) are disproportionately at risk of extreme heat emergencies. [1] People over 65 don’t sweat as much as younger adults, which is one of the body’s most important heat-regulation mechanisms, and seniors also store fat differently, which further complicates heat regulation in the body. [3]

Key Summer Safety Tips for Seniors

• Stay hydrated — don’t wait until you’re thirsty. Drink plenty of cool water, juice, or sports drinks throughout the day. [3] As we grow older, our bodies have less ability to hold on to water and to feel thirsty, so dehydration can set in before you realize it. [4]
• Limit outdoor activity during peak heat hours. Avoid outdoor activities and exercise during the hottest times of the day, typically between 10 a.m. and 4 p.m. [5]
• Dress appropriately. Wear lightweight, light-colored, loose-fitting clothing. Natural fabrics such as cotton may feel cooler than synthetic fibers. [2]
• Use air conditioning. Stay in air-conditioned buildings as much as possible. If your home doesn’t have air conditioning, contact your local health department or locate an air-conditioned shelter in your area. [3] The federal Low-Income Home Energy Assistance Program (LIHEAP) helps adults 65 and older with limited incomes cover the cost of air conditioners and utility bills — call 1-866-674-6327 for more information. [6]
• Know the warning signs. Early warning signs of heat exhaustion include excessive sweating, tiredness and weakness, and dizziness, headache, and muscle cramps. [1] Seek medical care immediately if you or someone you know experiences these symptoms. [3]
• Review your medications. Many common medications for blood pressure, heart conditions, or bladder control can increase the risk of dehydration or interfere with your body’s ability to handle heat. Before summer or if you anticipate a heat wave, schedule a medication review with your physician or pharmacist. [7]

Wildfire Smoke and Air Quality Alerts in SLO County

Wildfire season is a reality of life on the Central Coast. Smoke and ash from wildfires contain very small particles known as particulate matter that can travel hundreds of miles, harming the lungs and heart and causing coughing, wheezing, breathing difficulty, chest pain, and nausea. People with heart or lung disease, older adults, kids, and pregnant women are especially sensitive. [8]

The San Luis Obispo County Air Pollution Control District (SLO County APCD) closely monitors local air quality during wildfire events and provides daily forecasts and alerts. [9] During wildfire events, it is important to limit your exposure to smoke — especially if you may be more vulnerable to its health impacts. [9]

What Seniors and Families Should Do During Smoke Events

• Stay indoors. The best protection against wildfire smoke is to stay indoors as much as possible when smoke is present. [8] Keep windows and exterior doors closed.
• Create a clean air room. Put a HEPA (High-Efficiency Particulate Air) purifier in a room where you spend a lot of time, like a bedroom. [8]
• Sign up for air quality alerts. San Luis Obispo County residents can sign up for air quality alerts and notifications through the SLO County APCD at SLOCleanAir.org/air-quality-alerts. [8]
• Monitor the Air Quality Index (AQI). The current and forecasted AQI is available via the APCD website at slocleanair.org. [10] When the AQI reaches the orange “unhealthy for sensitive groups” range (100–150), elderly residents, children, and those with existing heart and lung conditions may begin to experience health effects. [11]
• Older adults and children should avoid prolonged exposure, strenuous activity, or heavy exertion during smoke events, as conditions dictate. [10]

Sign Up for AlertSLO

San Luis Obispo County has launched AlertSLO, a free mass notification system that allows residents to register to receive important information directly impacting their daily lives. [12] Notifications include severe weather, road closures, large power outages, 911 outages, public health emergencies, and important community information. [13] Families are strongly encouraged to help their senior loved ones register for AlertSLO so they receive timely warnings about wildfires, weather events, and other local emergencies.

The County of San Luis Obispo also utilizes other alert and notification systems including the Emergency Alert System, Early Warning System sirens, and Wireless Emergency Alerts (WEA). [14] For more information, visit prepareslo.org.

Fall and Winter: Rain, Slips, and Staying Warm

While SLO County winters are mild compared to much of the country, the rainy season brings its own hazards for older adults. Slick surfaces created by rain can be especially hazardous to older adults. [15] Falls are the leading cause of injury for older adults, and slippery surfaces from wet weather pose a predictable risk. [15]

Cold weather can also strain circulation and joints, even in mild climates. [16] Older adults are more likely to have chronic medical conditions — such as diabetes, thyroid problems, Parkinson’s disease, and arthritis — that make it harder to stay warm and maintain balance. [17]

Fall and Winter Safety Tips

• Wear appropriate footwear. Choose shoes with non-slip, rubber soles and good traction. Avoid smooth soles or shoes that get heavy when wet.
• Clear walkways. Keep outdoor walkways clear of wet leaves and debris. Use coarse outdoor mats near entry doors to trap water before it hits indoor floors. Add hand railings or grab bars by steps and other outdoor spaces where slips and falls are more likely to occur. [18]
• Improve lighting. Install motion-sensor lights to improve visibility in key areas like driveways and entryways. [18]
• Stay active indoors. It’s important to keep your body in motion during fall and winter months. Low-impact indoor workouts — like chair yoga, tai chi, or light resistance bands — are great options to keep your body moving when the weather is wet. Chair yoga is a gentle way to improve flexibility, balance, and mobility, making it perfect for seniors who want to stay active without strain. [19]
• Stay connected. Winter weather can make it tough to get outside or do your usual activities. Be sure to stay connected with phone check-ins, video calls, game nights, and group meals. [20]
• Watch for wood smoke. During winter months, the SLO County APCD issues “Don’t Light Tonight” advisories asking residents to voluntarily refrain from burning wood or using fireplaces on days with higher forecasted air pollution levels. Historically, these high particle pollution levels from wood smoke occur in the northern portion of SLO County, including Paso Robles, Atascadero, and Templeton. [21]

Spring: Refreshing Routines and Renewed Wellness

Spring on the Central Coast is a beautiful time of year — and a wonderful opportunity for seniors to refresh their daily routines. After a long winter indoors, even small changes like more natural light, fresh air, or gentle movement can have a real impact on mood and overall well-being. [22]

Increased exposure to sunlight boosts vitamin D levels, which plays a key role in mood regulation and reducing symptoms of depression in older adults. [22] Gentle outdoor activity also becomes more accessible in spring — even low-impact movement like walking or gardening is associated with lower rates of disability and improved mobility in older adults. [22]

Spring Wellness Tips

• Get outside gently. Take short walks in the morning when temperatures are comfortable. Even 15–20 minutes of outdoor activity can boost mood and energy.
• Refresh your diet. Spring is a great time to freshen up eating habits with lighter, nutrient-rich foods that support energy, digestion, and hydration. [22]
• Check your medications. Some medications raise heat or cold sensitivity or dehydration risk, so be sure to review yours with your provider as the seasons change. [20]
• Update your emergency plan. Spring is also a good time to review your household emergency plan, update your emergency contacts, and make sure you’re registered for AlertSLO and SLO County APCD air quality alerts before wildfire season begins.
