Weather bureau says that as 2023 is an El Nino year, typhoons will be stronger
The number of typhoons in the Western Pacific has been low this year, but their number should reach the annual average before year’s end, forecasters say. However, more important than the frequency of typhoons is their intensity this year. This year is an El Nino year. The phenomenon means that typhoons form farther away and get stronger before reaching Taiwan.
Taipei was hot and sunny on Friday morning, and temperatures are expected to remain high for the coming week. Only three typhoons have formed over the Western Pacific Ocean so far this year, well below the average of 4.3, but the Central Weather Bureau says between 21 and 25 more typhoons may hit the region before the year is over. Those reaching Taiwan should be on par with the annual average, it said.

There should still be around four or five typhoons that reach Taiwan this year. Those numbers comply with our statistics, and there have been other El Nino years with similar numbers. We estimate that the number of typhoons that reach Taiwan this year will be close to normal values.
Although the number of typhoons reaching Taiwan this year will be within annual norms, during El Nino years typhoons tend to be stronger.

During El Nino years, typhoons form farther from Taiwan. Therefore, to reach Taiwan a typhoon has to travel farther, and will pick up more warm water from the ocean, which will give it more energy. So, normally the typhoons that reach Taiwan during El Nino years are stronger.
In Taiwan, temperatures tend to rise and fall frequently in May. Then, in June, the western half of Taiwan proper tends to be warmer. Between July and September, temperatures normalize and tend to stay high, and rainfall decreases. This trend is the same in 2023, but the weather bureau says that as an El Nino year, typhoons are expected to be stronger.
