Spring tides occur during the full moon and the new moon when the earth, moon and sun are in line, creating a stronger force of attraction. Using tidal coefficients, professionals and amateurs alike can predict the size of the tide and thus avoid being taken by surprise when the tide comes in. This "scale" runs from 20 (lowest neap tide) to 120 (equinoctial spring tide). Spring tides are those with a coefficient of 95 or more.
