Tidal Light was a Thoroughbred racehorse who was the champion filly of her year and beat the colts in the 1987 New Zealand Derby.
After finishing second in her debut, Tidal Light won ten of her next 13 races, including the Derby, Avondale Guineas, Waikato Guineas, Canterbury Guineas and a Group 1 victory in the Air New Zealand Stakes over older horses under weight-for-age conditions, beating the great Solveig.
She was ridden in most of her 3 year old races by the 1986-87 champion apprentice, Michael Coleman.
She returned in the spring of 1987 as a four-year-old, but failed to win a race and despite some good performances was obviously not the same horse she had been the previous season.
She produced 12 foals for seven race winners and was at Woodlands Stud in Hunter Valley, Australia.
