Benchmark January palm oil futures on the Bursa Malaysia Derivatives Exchange ended 0.6 percent higher at 2,976 Malaysian ringgit ($950) a tonne after going as high as 2,978 ringgit.
Traded volumes for the January palm contract were thin at 9,386 lots of 25 tonnes each, compared with 12,369 lots on Wednesday.
"Seasonally we now move into lower production months from November to January, which is very positive for the crude palm oil market," said a Kuala Lumpur-based trader. "Production will taper off with weather calamities -- rain -- around the corner."
Benchmark palm prices have gained as much as 9.2 percent since hitting a multi-month low at 2,754 ringgit in early October, partly on expectations of lower output in Southeast Asia due to the onset of the rainy season.
The rainy season for more than a third of Indonesia, the world's top palm oil producer, began in October, while it will start this month for another third of the vast archipelago, the state weather agency said in September.
"For palm fundamentals, they are looking quite good," said a second Kuala Lumpur-based palm trader. "The weather factor is coming -- in Malaysia it's raining every week."
In addition, La Nina-driven heavy rains at the end of the year could also coincide with the monsoon season, stalling harvesting and supporting palm oil futures that have lost around 20 percent so far this year.
Production currently appears to be strong with traders expecting Malaysian palm oil stocks to record an increase despite the strong export data reported for October.
Palm oil was largely negative during the early stages of Thursday's session, with investors concerned about the uncertainty surrounding euro zone debt.
The threat of a Greek exit from the euro hung over a meeting of G20 leaders after France and Germany made clear that Athens must decide urgently whether it wants to stay in the 12-year-old currency bloc.
"This Greek sovereign debt issue has been dragging off and on," said a third Kuala Lumpur-based palm trader. "There is a lot of uncertainty.
Oil prices slipped to around $109 a barrel as uncertainty over the Greek bail out weighed on sentiment and the market digested bearish news of a crude oil inventory build in the United States.
In other news, Indonesia will not need to cut its palm oil export tax system, if it agrees a rice import deal with India, the state procurement agency Bulog and trade ministry in the Southeast Asia country said on Thursday.
After meeting Indonesian officials in New Delhi on Wednesday, India said it was willing to sell 500,000 tonnes of rice to Indonesia but wanted Jakarta to cut its export tax on crude palm oil which has threatened India's domestic refining industry.
Malaysia, the world's No 2 producer, says its refiners are suffering a price disadvantage after Jakarta slashed refined palm oil export duties and tariffs for the crude grade to keep more of the feedstock in Indonesia for processing.
