Weather conditions from Jan to April? (Bali)

I have some free time and looking into moving to SE Asia for about 3 months. Out of many options I seem to like Bali the most, nice combination of nature, sights and town-life. My only concern is weather. I would be coming mid-Jan and would stay until around April or May and that period seems to be a wet-season. How concerned I should be about that? What are the weather conditions like during a course of a day?
