Nate Jacobs is a central character in the HBO series “Euphoria.” He is portrayed as a high school student in the show, but his exact age is not specified. However, based on various hints and clues throughout the series, it is possible to make an educated guess about his age.

Firstly, it is established early on in the show that Nate is a junior in high school. In the United States, students typically enter high school in the 9th grade at around 14 or 15 years old. This would mean that Nate is likely either 16 or 17 years old, depending on whether he entered high school at the younger or older end of the spectrum.
Another clue to Nate’s age can be found in his birthday, which is revealed in the Season 1 episode “The Next Episode.” In this episode, Nate’s father, Cal Jacobs, throws a party for Nate’s birthday, and a banner in the background reads “Happy 17th Birthday Nate!” This would seem to confirm that Nate is 17 years old during the events of Season 1.
However, it is worth noting that there is some ambiguity around this detail. Some viewers have pointed out that the banner could be interpreted as reading “Happy Birthday 17 Nate!” in which case it would not necessarily be confirming Nate’s exact age. Additionally, it is possible that the party is not taking place on Nate’s actual birthday, and the banner is simply indicating that he is turning 17 at some point around the time of the party.
Aside from these clues, there are a few other factors to consider when trying to determine Nate’s age. One is his physical appearance. Nate is played by actor Jacob Elordi, who was born on June 26, 1997. This would make him 22 years old during the production of “Euphoria” Season 1, which was filmed in 2018. While actors playing high school students are often older than their characters, it is unlikely that Elordi would have been cast as Nate if the character was meant to be significantly younger than 17.
Another factor to consider is the timeline of the show. While “Euphoria” does not always follow a strict chronological order, it is established that the events of Season 1 take place over the course of one school year. This would suggest that Nate is in his junior year of high school for the entirety of the season.
In conclusion, based on the evidence presented, it seems likely that Nate Jacobs is 17 years old during the events of “Euphoria” Season 1. While there is some ambiguity around this detail, the fact that he is referred to as a junior in high school, the birthday banner seen in one episode, and the physical appearance of the actor all support this conclusion.
