Surfers were making the most of the big swell today as winds whipped up the ocean.

Sydney might have missed out on the cyclonic conditions that buffeted the NSW south coast over the weekend but the rain is here to stay.

Meteorologists say the city's wettest May in seven years will roll on into June, with a number of developing troughs promising to pepper the city with showers over the next few weeks.

"Looking beyond the current week there is a very good potential for troughs to develop and, as a result of that, unfortunately if you like the sunshine, it's probably going to mean cloudy skies and plenty more rainfall to come in the following weeks," weatherzone.com.au forecaster Martin Palmer said.
