South Florida’s dry season is expected to kick in any day now, but it might prove wetter than normal, which would be in keeping with a year that may wind up breaking records for rain in some cities, including Miami.

Although the region’s annual rainy season typically ends around Oct. 16, Robert Molleda, a forecaster with the National Weather Service’s Miami office, said that El Niño and other global weather patterns could make the fall and winter slightly wetter, as well as cooler, than average.

But he stressed during an annual dry-season forecast on Friday that a weak El Niño, which is marked by warm Pacific Ocean temperatures that influence weather around the world, added considerable uncertainty to the predictions.

With 45 to 65 inches of rain recorded during the wet season — close to a year’s worth along much of the Southeast coast — the region doesn’t need more rain, said Susan Sylvester, chief of operations for the South Florida Water Management District.

Some Everglades water-conservation areas still have too much water, and federal engineers are trying to slowly drain Lake Okeechobee, where water levels neared 16 feet above sea level. All of the rain has erased water-shortage concerns. Overall, regional supplies are right “at the sweet spot” going into the dry season, she said. The dry season typically runs from mid-October to mid-May.
