The effect of weather conditions on the rate of all deaths due to fatal self-harm (suicides, misadventure & open verdicts) were studied in North Cheshire, UK for the period 1989-1993. Small but significant positive correlations were demonstrated between the occurrence of fatal self-harm & hours of sunshine & diurnal variations in daily temperature. These effects were independent of gender & psychiatric history. Rates of fatal self-harm did not appear to be related to extreme weather conditions.
