You are too vague in your question to answer it fully. But I'll take a whack at it. If you are talking about girls who have not yet reached puberty, then hormones are a minor part of their lives. Same with boys. However, once girls reach puberty (anwywhere from 8-16 years of age), then there is a monthly cycle which can be as regular as a clock or so irregular, it's scary!
This is especially true of younger girls/women. USUALLY, girls' hormones (estrogen) will be highest at mid-cycle -or mid-month, depending when they ovulate (when the egg is released from the ovary and ready to be fertilized), and then drop off until the cycle begins again. Girls and women are often more sexually aroused just before and during ovulation than at other times.
HOWEVER...humans are one of the few mammalian species in which the female REMAINS RECEPTIVE TO SEX throughout her cycle, regardless of whether she's ovulating or not. This is very important, as intercourse alone can actually TRIGGER ovulation, and hence, pregnancy.
IT IS IMPORTANT TO REALIZE THAT HUMAN FEMALE OVULATION CAN OCCUR ANY TIME DURING THE CYCLE!
As for men, they have hormone fluctuations, but they are more on a daily basis, with the highest level of testosterone (male hormone) in the morning, and the lowest in the early evening. This is why men are more "horny" in the AM.
If you specified WHY you want to know (just go to the add details section, I could give you a more accurate response).

Hormone rhythms are the regular patterns in which the levels of different hormones normally fluctuate in the body. Some hormone rhythms show high and low peaks occurring every few minutes or hours while other hormones fluctuate over a 24-hour cycle. The 24-hour pattern of hormone cycling is referred to as a circadian rhythm and seems to be directed by the "biological clock" in the brain. An example of a hormone that follows this circadium rhythm is growth hormone.
Other hormones, such as those of the menstrual cycle, follow a release pattern that is on a monthly basis. These hormonal time-release systems are controlled by the brain and are designed to optimize the body's ability to respond to changes in the surrounding physical environment such as alterations in the light-dark cycle. From an evolutionary point of view, hormonal rhythms strengthen the body's survival mechanisms and reproductive capabilities.

ANAHEIM, Calif. – Hormone fluctuations resulting from life cycle changes are a factor in higher rates of asthma, more frequent emergency department visits, and higher hospital admission rates in women than in men according to reports at the annual meeting of the American College of Allergy, Asthma and Immunology (ACAAI) in Anaheim.
“Since we began observing a correlation between women’s hormonal status and asthma symptom patterns, investigators are studying asthma incidence and mortality in relation to premenstrual and perimenstrual cycles,” said Nancy K. Ostrom, M.D., at the University of California and the Allergy & Asthma Medical Group and Research Center in San Diego.
“Women between the ages of 20-50 years are more than three times as likely as men to be hospitalized with asthma despite comparable spirometry. Studies have demonstrated a relationship between asthma and the menstrual cycle, with 46 percent of women’s hospital admissions perimenstrual, and up to 40 percent of women having premenstrual asthma symptoms,” Dr. Ostrom said.
