Human observers stationed on or near beaches gather subjective observations of one or more observable beach conditions associated with respiratory distress. Subjectively determined observations such as dead fish and audible coughing provide a better indication of the likelihood of respiratory distress than measurements made using scientific instruments. The observations may be sent to a remote central database using handheld communication devices. A beach status evaluation is determined based on stored observations, and may be provided to beachgoers through Internet web pages or by telephone or text-message to enable beachgoers to choose an alternative beach or alternative activity when respiratory distress is likely.
