What month does it usually have the heaviest rainfall in Los Angeles
It's usually rainy during the months of January and February records the heaviest precipitation compare with the other month in Los Angeles. And then it slowly subsides during April and May.
During summer there's almost no precipitation record which means there's very little to no rain during those months, June and July specifically. Then it will start to pour again in November and December.
