September has a way of making change feel especially noticeable. Summer begins to wind down, evenings arrive a little earlier, temperatures start to cool, and familiar routines return. Here in the Pacific Northwest, we also know what is coming. The long, bright days of summer gradually give way to shorter days, more clouds, and eventually plenty of rain.
For some people, this transition feels comforting. Fall can mean cozy evenings, changing leaves, favorite traditions, and a return to routine. For others, the shift can bring an unexpected change in mood, energy, motivation, or sleep. Sometimes it is subtle enough that we do not immediately connect how we are feeling with the changing season.
Our environment affects us, and paying attention to those changes can be an important part of caring for our mental health.
Why Seasonal Changes Can Affect How We Feel
Our bodies respond to light, temperature, routines, activity levels, and many other signals from the world around us. When those things change, we may notice changes in ourselves as well.
Think about how different life can look between July and November. During summer, there may be more opportunities to spend time outside, socialize, exercise, travel, garden, attend community events, or simply sit outdoors after dinner. Longer daylight hours can make the day feel more spacious.
As fall approaches, those patterns often change. We may leave home when it is darker and return when daylight is already disappearing. Rain or colder weather can make outdoor activities less appealing. Schedules become busier as schools, workplaces, organizations, and families settle into fall routines.
None of those changes are necessarily negative. Still, when several happen at once, they can affect our mental and emotional well-being.
Some people notice that they are sleeping more or having a harder time getting out of bed. Others may feel less motivated, more irritable, more withdrawn, or simply not quite like themselves. Activities that normally sound enjoyable might suddenly require more effort.
Recognizing these changes does not mean something is automatically wrong. It simply gives us an opportunity to pay attention.
When It’s More Than the “Winter Blues”

Many people casually use phrases such as the “winter blues” to describe feeling less energetic or cheerful during darker months. For some people, however, seasonal changes are associated with a form of depression known as Seasonal Affective Disorder, or SAD.
Seasonal Affective Disorder is a type of depression that follows a recurring seasonal pattern. It most commonly begins during fall or winter, although seasonal depression can occur at other times of year as well.
Symptoms can include persistent sadness, loss of interest in activities, changes in sleep or appetite, low energy, difficulty concentrating, feelings of hopelessness, and withdrawing from other people. Because some of these experiences can easily be blamed on being tired, busy, or dealing with gloomy weather, seasonal depression can sometimes go unrecognized.
Keep Some Daylight in Your Day
When the days get shorter, spending time outside can become something we have to do more intentionally.
A short walk during lunch, sitting outside for a few minutes in the morning, taking the dog around the neighborhood, or spending time near a window may help keep daylight and outdoor time part of your routine.
It does not need to be a major excursion.
One of the wonderful things about living in Southwest Washington is that nature is rarely very far away. Even when the weather changes, there are still opportunities to notice trees changing color, listen to rain, walk through a neighborhood, or visit a local park.
Sometimes caring for our mental health is less about adding another complicated task to our schedule and more about protecting small things that already make us feel better.
Don’t Let Connection Disappear With Summer
Summer tends to create natural opportunities for connection. People gather outside, attend events, take vacations, visit friends, and spend more time in public spaces.
When colder weather arrives, it can become easier to retreat indoors.
For someone who is already experiencing depression, anxiety, loneliness, or another mental health condition, that isolation can become particularly difficult.
Connection does not have to mean having a packed social calendar. It might mean calling someone you trust, meeting a friend for a walk, attending a support group, participating in a class, volunteering, or simply making a point of regularly spending time with people who help you feel comfortable being yourself.
Mental wellness does not require us to be social all the time. We all need different amounts of interaction and solitude. The important thing is noticing when solitude has shifted into isolation.
A New Season Can Be an Opportunity
Seasonal transitions can also offer something valuable: a natural moment to check in with ourselves.
September can be an opportunity to ask what has been working, what has not, and what we would like to carry with us into the months ahead.
Maybe summer reminded you how much better you feel when you spend time outside. Perhaps you discovered that you need more connection than you realized. Maybe you have been moving at a pace that is no longer sustainable.
You do not have to completely reinvent your life because the calendar changed.
Choose one or two things that support your well-being and make room for them as fall arrives.
Most importantly, remember that changes in mental health deserve the same attention and compassion we give changes in physical health. If you begin noticing that you are struggling, reach out. Talk with someone you trust, connect with your support system, or seek professional help.
The seasons change, and sometimes we change with them. Paying attention gives us a chance to care for ourselves along the way.
