Honolulu (KHON2) — NOAA released its forecast for the rainy season in Hawaii on Friday. This predicts above average rainfall throughout the rainy season.

The rainy season usually begins in October and lasts until April. The La Niña phenomenon will cause the state to see more rainfall towards December.

Kevin Kodama, Senior Services Hydrologist at the Honolulu Forecasting Bureau, said: “Model forecasts begin off-dry in October, move to November, and begin to have above-average rainfall after December.

The current situation may continue until the spring of 2021. However, the strength of La Nina affects which part of the island it rains the most.

Rain does not come immediately, especially on Maui, for ranchers and farmers who have been hit by long-term droughts.

“For some ranchers, the drought has been disastrous,” explained Nicole Galase, managing director of the Hawaii Cowherd Council. “They can strategically graze certain grasses in a short period of time and can last for such a short time. Well, after a few years of continuous drought, you run into problems. . “

The La Niña phenomenon brings rainy conditions to the state.

The strong La Niña phenomenon increases the likelihood of rainfall on upwind slopes. On the other hand, the weak La Niña phenomenon causes considerable rainfall on the leeward side.

“For now, this prediction shows that this could be a fairly important event on the stronger side,” Kodama explained. “If so, unfortunately, the intense drought seen on Maui could continue.”

Rainfall is seen in Maui County during this rainy season, but it is not enough to drive them out of the current drought of the La Nina phenomenon.

“There are some streams that have actually dried only a few times in 30 years, and this is one of them,” said Dr. Kyle Cares, who works for the University of Hawaii at Manoa Livestock Program Expansion Program.

In the current situation on Maui, chitals are grazing in the meadows due to lack of grass growth. Due to the dry condition, the auxiliary feeding rancher started.

“Deer really contribute to overgrazing, and in the absence of their moisture, they help the grass bounce. It’s a vicious cycle,” explained Dr. Caires.

Maui and southern Hawaii do not benefit from the strong seasons of La Nina, but NOAA predicts that the western part of the state will benefit.

“Like Kauai and Oahu, we are now suffering from drought and we are confident that there is a good chance of recovery,” Kodama said.

NOAA also said that the stronger La Niña phenomenon is higher than the normal trade wind frequency, which concentrates rainfall in upwind areas.

Small islands such as Kauai and Molokai, as well as upwind slopes on Maui and the Big Island, are more likely to recover from the drought.

However, the potential for drought is expected to continue throughout the rainy season, especially in the leeward areas of Maui and the Big Island.
