When we think of the “winter blues,” most of us picture grey skies, shorter days, and colder weather. But did you know some people experience low mood in the summer, too?

While less common than seasonal affective disorder (SAD) in the winter months, summer-onset depression is a real phenomenon — and older adults can be especially vulnerable.

 

What causes the “summer blues”?

For some, summer brings disruptions to routines that support well-being: community programs pause, family routines shift, and caregivers or loved ones may travel more. These changes can lead to feelings of disconnection or loneliness.

Summer can also stir up grief for those who’ve lost a partner or close friend. Memories tied to vacations or traditions may feel especially poignant this time of year.

In addition, extreme heat can limit outdoor activity, disrupt sleep, and contribute to fatigue — all of which can affect mood and motivation.

 

What can you do?

1. Stick to a routine. Regular wake-up times, meals, and movement can help anchor your day and support mental health.

2. Find connection. Schedule a weekly call with a friend, join a community centre activity, or explore online discussion groups that match your interests.

3. Plan something meaningful. Whether it’s tending a garden, visiting a museum, or volunteering, having something to look forward to can be a powerful mood booster.

4. Know when to seek help. If feelings of sadness persist or interfere with daily life, talk to your doctor. There is support available — and you don’t have to face it alone.

 

Summer doesn’t feel sunny for everyone — and that’s okay. Recognizing the signs and taking small steps to care for your emotional well-being can make a big difference.
