Adverse Weather Conditions Occur
Impact of Unpredictable Weather on Mood: A Psychological Perspective
Montreal has experienced a rollercoaster of weather this May, with a drastic drop in temperatures on May 23. The unusually cold weather has left many locals feeling down and unenthused, leading to questions about the connection between weather and mood. To unravel this phenomenon, we consulted with experts.
According to Peter Kimbell, a meteorologist at Environment Canada, the city experienced four consecutive days with maximum temperatures near 26–27°C between May 13 and 16. However, a significant change occurred on May 23, with temperatures only reaching 12°C, nearly breaking a cold record dating back to 1892.
This weather volatility poses consequences for Montrealers' moods, but what does science imply? Perry Samuel Adler, a clinical psychologist and professor at McGill University, illuminates three major mechanisms through which weather may influence mood:
- Biological Mechanism: Since natural light regulates our biological clock, a scarcity of light leads to a decrease in serotonin – often referred to as the "happiness hormone" – and an increase in melatonin – the sleep hormone. This hormonal imbalance promotes fatigue, lethargy, and a somewhat depressive mood.
- Behavioral Factors: Bad weather often restricts outdoor activities, lessening physical exercise and social interactions – factors that are known to support mood.
- Cognitive Aspect: Our perception of the weather can influence our emotions. For instance, associating sunshine with happiness and rain with sadness may increase our vulnerability to weather-induced mood fluctuations.
Not everyone, however, is affected equally by these factors. While most people experience a minor dip in mood during long stretches of gray weather, only a minority demonstrates true meteorological sensitivity in a medical context. Individuals with an anxious or depressive background are more susceptible to having their mood swayed by the weather, explains Adler.
On the flip side, some individuals find comfort in rainy weather, often deriving sensory pleasure from the scent, sound, and feel of raindrops. This reaction can be attributed to a combination of psychological and physiological factors. Some find the sound of rain to be calming and conducive to relaxation, while others associate rain with nostalgia or peaceful memories.
In an effort to boost spirits during rainy periods, Adler recommends avoiding social isolation and maintaining contact with friends, as well as incorporating light therapy, vitamin D supplementation, and physical exercise into daily routines.
Despite the impression of gloomy weather, meteorological data suggests that May is nearly within the norms for temperature and precipitation. The variability in weather patterns observed is not unique to this year.
As of writing, data on sunlight levels for May 2025 is not yet available, which may help explain the perception of the current month. Yet, according to Peter Kimbell, the sunshine will make its return starting from Monday, with sustained periods of heat expected from early June.
Finding comfort in the rain? For some, the sound and rhythm of rain can serve as a relaxing and grounding influence, aiding in concentration, stress reduction, and improved mood. Cultural upbringing and personal experiences can also play a role in our reactions to rainfall.

- The drastic drop in temperatures experienced in Montreal this May has sparked discussions about the potential connection between the environment, climate change, and mental health.
- To further explore this relationship, experts in environmental science, health-and-wellness, nutrition, and fitness-and-exercise suggested various factors that could contribute to weather-induced mood changes.
- One of the proposed mechanisms is the biological mechanism, which indicates that a scarcity of natural light, due to unpredictable weather, can lead to hormonal imbalances like decreased serotonin levels, potentially contributing to depressive moods.
- In addition, unpredictable weather can reduce opportunities for outdoor activities, thus affecting our physical health through reduced exercise, which in turn, can impact our mental health and overall well-being.
