What times were the High tides at Wynnum for 19 Oct - 20 Oct?
10.12am, 11.42am and 11.18am
4.35am and 5.36am
4.56pm and 5.50pm
4.35am, 4.56pm, 5.36am and 5.50pm
Why are the high tides lower on Wednesday 19th compared to Tuesday 25th?
The moon is in a quarter phase on the 19th so the Moon and Sun aren't lined up pulling together. On the 24th it is closer to a new moon so therefore it is lined up with the sun more closely and the Moon and Sun are pulling the water together. This makes the water heights higher because the pull is stronger.
