A drought in Malaysia has led to a spike in durian prices, with some sellers here charging over $10 a kilogram more than they were a year ago.

June and July usually form the peak season for the 'king of fruits' but the dry weather has decimated crops, and peak season is now expected to be delayed until the end of this month.

"We have plantations in Johor and Pahang, where there has been a decrease in harvest by more than half," said Mr Alvin Teo, 30, owner of Fruits Top 1 Department Store.

He is selling 1kg of Mao Shan Wang for $27, up from $16 last year. Despite the price increase, customers still buy and he sells out his stock every day.

Mr Teo hopes that supply will return to peak level and that prices will return to normal, but added: "We have to see the bumper harvest this year first."

Mr Alun Zhou, owner of 101 Fruits, said there was also a dry spell in March and April.

"It takes 90 to 120 days for one cycle of harvest. With no water, even if there is sunshine, the land will be dry and not fertile," he said

According to Mr Zhou, who has been in the business for 40 years, local durian sellers also face competition as suppliers also supply to other markets in the region.

He added that regular customers now buy smaller amounts, just to try the taste of the fruit.

Prices at Combat Durian in Balestier Road are the highest they have been for five years.

Owner Madam Linda Ang, who is in her early 50s, said: "Usually the bumper crop is in July. But Malaysia had the drought, so the harvesting is delayed."

She currently sells Mao Shan Wang at $28 per kilogram. It was $18 to $20 per kilogram this time last year.

"Some customers are filled with disappointment, while some of them don't mind. They crave for it, they pay for it."

While there are alternative sources such as Thailand, Madam Ang only brings in durians from Malaysia, as the Thai ones were affected by the droughts too.

"Furthermore, the quality is not what Singapore customers want."

Administrator Madam Linda Yeo said her family loves durians and she is willing to fork out the extra dollars if the taste is good.

'We will buy regardless of the price. We are really more concerned about the quality of the fruit."
