Mozambique end of March-early April

Hi, I am traveling to Tofo and possibly to Ihla de Mocambique from the 24th of March-April 8th, 2012. Tickets are more reasonable at this period, but could it be because of the weather? What is your experience with the weather at this time and does it downpour all day or do you just get a daily shower for an hour?

I researched websites online, most of which has March as part of the rainy season, but I've also read a few sites that has March pretty dry. How have things been these past few years?

Thanks in advance. M
