June is still over a week away,... but it feels like summer is already here.<br />For those of you in Korea, if you thought yesterday was hot, beware of some extra sizzling temperatures today.<br />Seoul is expected to come under its first heat wave advisory of the year. <br />While this summer isn't expected to be as hot as last year,... it's still going to be a sizzler so have your mini-fan, shade and sunscreen at the ready. <br />Lee Seung-jae starts us off. <br />A 'cooling fog' system, which is used to cool down citizens during the peak of summer, has already been activated in parts of South Korea.<br />And Daegu, a city known to be one of the hottest in the nation, is already feeling the summer heat.<br /><br />I didn't think it was going to be hot since it's May. Now that I'm outside, it's hot. I'm quite worried about June, July and August."<br /><br />In Seoul,... temperatures have also risen sharply.<br />As the mercury soars past 30 degrees Celsius, the year's first heat wave advisory will be issued on Friday.<br />It marks just the second time that Seoul will be under a heat wave advisory in May,... since May 2016.<br />Advisories are also being issued in other parts of the nation.<br />Temperatures are higher than the seasonal average due to a high pressure system from the North Pacific and high thermal pressure from China.<br />However, experts say this summer won't be as sweltering as last year, which was one of the hottest on record.<br /><br />"During spring, Tibet was covered with snow, so the possibility of a strong and constant heat wave like last year is expected to be small.<br />The monsoon season is expected to arrive later than usual, with most of the summer rain to be concentrated in southern regions.<br />However, after monsoon season,... bouts of heavy rain are expected across the country.<br /> Just like last year, between one to three typhoons are expected to affect South Korea,... but forecasters also warn there's a possibility of a super-typhoon due to the El Nino effect.<br />Lee Seung-jae, Arirang News. <br />
