okay, so you could start with 'Quand' which means 'When' and continue with 'il pleut'. Together, you have 'When it is raining'. You could say things such as whether you like/dislike this season using 'j'aime' (I like) or 'je n'aime pas' (I dislike). You could also say 'J'adore' (I love), 'Je deteste' (i hate) or 'je prefere' (I prefer). You could talk about what you do when it rains, and how often. For exampe, 'Every Day' in French is 'Tous le Jours' etc etc. if you need some words, the don't use Google Translate - it's really inaccurate. A better site to use is Wordreference.com. Good Luck ;)
