Prior studies on the association between weather and psychological changes have produced mixed results. In part, this inconsistency may be because weather's psychological effects are moderated by two important factors: the season and time spent outside. In two correlational studies and an experiment manipulating participants' time outdoors (total N = 605), pleasant weather (higher temperature or barometric pressure) was related to higher mood, better memory, and “broadened” cognitive style… 

Figures and Tables from this paper

How seasons, weather, and part of day influence baseline affective valence in laboratory research participants?

TLDR
The findings have methodological implications for studying emotions by suggesting that seasons and part of the day do not matter for baseline affective valence reported by participants, and the effects of ambient temperature are unlikely to influence most research.

Come rain or come shine: individual differences in how weather affects mood.

TLDR
Overall, the large individual differences in how people's moods were affected by weather reconciles the discrepancy between the generally held beliefs that weather has a substantive effect on mood and findings from previous research indicating that effects of weather on mood are limited or absent.

Weather conditions: a neglected factor in human salivary cortisol research?

TLDR
It is found that weather conditions are related to salivary cortisol concentration and that this relationship may be moderated by both the specific climate and the anticipation of immediate exposure to outdoors conditions.

The role of incidental variables of time in mood assessment

Determining what influences mood is important for theories of emotion and research on subjective well-being. We consider three sets of factors: activities in which people are engaged; individual

Does life seem better on a sunny day? Examining the association between daily weather conditions and life satisfaction judgments.

TLDR
Results show that weather does not reliably affect judgments of life satisfaction, and most daily weather conditions were unrelated to life satisfaction judgments.

Weather daily variation in winter and its effect on behavior and affective states in day-care children

TLDR
The data showed that relative humidity and solar radiation were the main predictors of the children’s emotional and behavioral states, suggesting that a sunny winter day makes children more cheerful.

Seasonal variation, weather and behavior in day-care children: a multilevel approach

TLDR
Results showed a different impact of some weather variables on children’s behavior across seasons, indicating that the weather variable that affects children's behavior is usually the one that shows extreme values during the studied seasons, such as air temperature and relative humidity in winter and summer.

The Role of Rumination in Predicting Seasonality

The impact of the changing seasons on mood and behavior (i.e., seasonality) has long been of interest to researchers. Recently, researchers have begun to look beyond biological explanations to

The effect of weather and its changes on emotional state – individual characteristics that make us vulnerable

TLDR
The results obtained by t-test showed that the different categories of weather led to changes in the emotional status, which indicates a character either positive or negative for the organism.

A multidimensional approach to the relationship between mood and weather.

TLDR
Ten mood variables were related to eight weather variables in a multidimensional study and humidity was the most significant predictor in regression and canonical correlation analysis, highlighting the importance of humidity as a weather variable.

Seasonal Variation of Depression and Other Moods: A Longitudinal Approach

TLDR
The results, based on those participants for whom mood measures were collected in each season, demonstrated strong seasonal effects and Beck Depression Inventory (BDI) scores were highest in winter and lowest in summer.

Mood and the mundane: relations between daily life events and self-reported mood.

TLDR
Daily mood ratings and corresponding diary entries were studied to determine relations between common events and two independent mood factors--Positive Affect (PA) and Negative Affect (NA)--in a sample of 18 young adults over a 3-month period and reaffirm the importance of assessing NA and PA independently.

Effects of light therapy on neuropsychological function and mood in seasonal affective disorder.

To date, little attention has been paid to changes in neuropsychological function in seasonal affective disorders (SAD). In this study, we investigated the performance of 30 patients with SAD on a

Seasonal affective disorder. A description of the syndrome and preliminary findings with light therapy.

TLDR
Preliminary studies in 11 patients suggest that extending the photoperiod with bright artificial light has an antidepressant effect and sleep recordings in nine depressed patients confirmed the presence of hypersomnia and showed increased sleep latency and reduced slow-wave (delta) sleep.

Personality and Cognitive Processing of Affective Information

Several studies have demonstrated that the personality traits of extraversion and neuroticism are positively correlated with susceptibilities to positive and negative affect, respectively. These

Timed bright-light exposure and complaints related to shift work among women.

TLDR
Light significantly alleviated the subjective distress associated with nightshift work, both in summer and in winter, independent of the subject's age, and was stronger for those who reported routine seasonal changes in mood.

Epidemiological findings of seasonal changes in mood and behavior. A telephone survey of Montgomery County, Maryland.

TLDR
It is apparent from this study that seasonal affective disorder represents the extreme end of the spectrum of seasonality that affects a large percentage of the general population and might provide valuable insight into pathogenesis, treatment, and prevention of affective illness.
