Jaehaerys had always been close to his sister-wife Alysanne, even as a child, and had always had a strong affection and regard for her. When he was younger, Jaehaerys had been fascinated by the ponderous tomes and Old Valyrian scrolls found in Dragonstone's library. He and Alysanne were known to stay at the inn at the crossroads during their journeys so much so, that afterwards it was renamed the Two Crowns. Jaehaerys was known for his love of travel, and made many royal progresses.

Following a rigorous training regime during his time on Dragonstone, he became skilled at arms as well, to the point where Ser Elyas Scales, Jaehaerys's master-at-arms claimed that Jaehaerys would never be skilled enough to join the Kingsguard, but that he had enough skill to beat his uncle Maegor in combat, had Maegor still lived. By the time he was fourteen years old, Jaehaerys was already skilled with lance and longbow. Nor was he a man who wasted time with reproaches, recriminations, or appeals. He was never shy about letting his voice being heard. Įven by the age of fourteen, Jaehaerys refused to allow his council to rule the realm in his name during his regency, and would involve himself in many of the issues the small council faced. According to the Sealord of Braavos, Jaehaerys was very skillful in making veiled threats. Nor did Jaehaerys like to make outright threats, but had other ways of making his disapproval felt. He never acted without thinking, and did not trust in chance.

In times of trouble, instead of brooding on the issues, Jaehaerys would shrug off his sorrows and plunge himself into his work. Jaehaerys was decisive in both thought and deed, and always sought the most peaceable ends. Queen Alyssa, Jaehaerys's mother, is reported to have called Jaehaerys 'the best of my three sons'. Although Benifer might have attempted to flatter Jaehaerys with such a statement, according to Archmaester Gyldayn there was some truth to it as well. According to Grand Maester Benifer Jaehaerys was 'learned as a maester and pious as a septon'. He was fair-spoken, open-handed, and as chivalrous as he was courageous. He wore as a crown a simple band of yellow gold ornamented with seven gems of different colors. It is said that his smile could warm the heart of any maiden, and his frown could make a man's blood run cold. At an older age, his beard had turned white, and had grown to reach his waist but he still stood unstooped and still looked wise and dignified. By 84 AC, at the age of fifty, Jaehaerys had grown thinner, almost gaunt, and his beard and hair had become more grey than gold. He was a tall and handsome man who wore his hair in a thick braid that fell almost to his waist and his facial hair had grown out into a handsome full golden beard, shot through with silver. By the time he had turned twenty-four, Jaehaerys looked “every inch a king”. Early in his reign he grew a wispy beard and mustache. At the age of sixteen, he wore his hair loose, flowing about his shoulders. According to a semi-canon source, Jaehaerys had the purple eyes of House Targaryen.
