Object.—To investigate the rhythmicity of migraine episodes without aura in a pediatric population. Methods.—Time of occurrence of 2517 migraine attacks in 115 children was recorded, by means of a diary, both by hourly and monthly intervals. Results.—A significant circadian variation, characterized by a peak in the afternoon ( P < .001) and one in the early morning ( P = .002) was found. A seasonal peak was also observed between November and January, while a nadir was observed in July. Conclusions.—The clustering of attacks in the morning and midday and in autumn‐winter, with a minimum frequency in July, suggests that school activities may represent an important cause of migraine.
