The Tourism Council of Thailand (TCT) projects total foreign tourists and revenue from them will exceed the 2015 targets set by the Tourism and Sports Ministry.
The forecast is based on a strong first-half performance and an expected recovery in the fourth quarter.
The private industry body expects 30 million foreign visitors generating tourism revenue of 1.5 trillion baht this year.
That would beat the ministry's target of 28.8 million visitors and 1.4 trillion baht in foreign tourism revenue.
The ministry expects overall tourism revenue of 2.2 trillion baht including 800 billion from domestic travellers.
"The bombing of the Erawan Shrine will prove to be just a hiccup for Thai tourism -- and mainly in Bangkok, as other tourism destinations are still doing well," TCT president Ittirit Kinglake said.
The TCT is confident tourism will fully bounce back in the fourth quarter.
A travel advisory by Hong Kong against Thailand is expected to be cancelled soon.
The impact of the bombing has been short-lived in Bangkok -- the monetary cost to Thai tourism is estimated at 62 million baht.
TCT figures show first-half tourist arrivals increased by 29.8% to 14.8 million.
It projects arrivals will grow by 26% to 7.42 million in the third quarter and 9.12% to 8.14 million in the fourth quarter.
The Asian market, particularly China, will remain a major driver boosting Thailand's tourism sector for the remainder of this year, Mr Ittirit said.
Chinese arrivals are projected at 8.27 million this year, up from 4.6 million last year.
"Thailand is always a favourite destination among foreign tourists, as reflected in the rapid recovery each time following the many crises over the past 10 years," Mr Ittirit said.
However, the TCT remains concerned about the domestic economic situation, as people's purchasing power continues to decline.
It believes the Tourism and Sports Ministry's forecast of 800 million baht in domestic tourism revenue this year will be missed.
Mr Ittirit said a more reasonable expectation was 700 billion baht.
But the overall 2.2-trillion-baht target should still be met thanks to greater-than-expected spending by foreign tourists, he said.
"We do hope the new economic measures under the economic team led by Deputy Prime Minister Somkid Jatusripitak will help to spur the economy as well as spending by Thais in the fourth quarter," Mr Ittirit said.
He said apart from domestic and global economic problems, local politics could again cause more uncertainty.
Thailand's image could be hurt, particularly in Europe and the US, by the draft constitution being rejected by the National Reform Council and the subsequent delay in the next general election.
The TCT also suggests tourism operators keep an eye on currency exchange, as fluctuations will directly hurt their business.
