Be sure to include detail within your setting that relates to time. For example, describe a setting that takes place in summer. A summer that is above normal temperatures could pose a threat. Or, maybe it doesn’t pose a threat, but it does give a clear indication of what time of year it is. Maybe the heat is depicted by way of the droopy leaves of the plants on the patio of the house your character lives in. Is it winter? Everyone knows that winter can present risks as well.
