March, April and May
The bright winter stars set early and the sky behind them is deep and quiet — spring is when you are looking out of our galaxy rather than along it, and the galaxies show.
Everything below is highest in the evening in these months. South of the equator the months are the same, but they fall in the opposite season.
Planets do not keep to seasons — they wander, which is what the word means. Each one has its own page with a month-by-month table saying when to look for it.
