The think-tank upped its UK growth projections for 2016 by 0.1% to 1.8%, highlighting a strong pre-referendum economic performance and prompt action by the Bank of England.
"While markets have since stabilised, sterling has depreciated by around 10% in trade-weighted terms since the referendum. For 2016, GDP growth has been supported by a strong performance prior to the referendum, even though business investment contracted," the OECD said.
The Bank was praised for its swift action following Britain's decision to quit the European Union, adding that its strong policy response helped to stabilise markets and also contributed to "moderate scenarios" following the June 23 vote.
Prior to the vote, the OECD had issued stark warnings that UK growth would be pummelled in the event of a Leave outcome.
A number of other economists have also brightened their outlook for the UK, upping their growth forecasts as Brexit uncertainty eased following a resilient performance from gross domestic product (GDP) in the run-up to the vote, coupled with a string of surveys pointing to a rebound in activity following July's slump.
Nevertheless, the OECD said growth next year would be "well below" pre-referendum forecasts.
"GDP is projected to slow to 1% in 2017, well below the pace in recent years and forecasts prior to the referendum. Uncertainty about the future path of policy and the reaction of the economy remains very high and risks remain to the downside."
It added that on the UK economy's long-term outlook, a future trading arrangement with the EU and other countries will be "critical to its economic prospects".
The group warned in July that Britain's decision to leave the EU could result in a 3% loss in GDP by the end of the decade and is likely to hit employment.
Globally, the OECD said weak trade and "financial distortions" are exacerbating slow growth, with the world economy expected to grow at a slower pace this year than in 2015, with only a modest uptick expected in 2017.
Its outlook also warned a "low-growth trap" has taken root, as poor growth expectations further depresses trade, investment, productivity and wages.
Global growth is now projected to come in at 2.9% this year, down from previous forecasts of 3%.
