In the newspaper one day you read that highest tides of the season are expected in the next month. What can you infer about the positions of the sun, earth, and moon? what phase of the moon will probably be visible?
Since this is not my area of expertise, I searched Google under the key words "tides" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
