Mathew gives us much more detail than John in telling about Jesus walking on water. It happened in the fourth watch of the night, which is the early morning hours. Evidently the disciples had been struggling against the wind nearly all night because John tells us the disciples had gone to the boats in the evening. He says they had rowed only three or four miles when they saw Jesus walking on the water (John 6:16-21; Mathew 14:22-33).
There are times when God allows us to struggle with the wind and the waves. But he allows it to teach us about himself and to cause us to trust in him.
None of us likes storms in our lives. But no storm is without purpose. It will yield the peaceable fruit of righteousness when God's work for that storm is finished(Hebrews 12:11).
