Not all animals have a mating season. The animals that do tend to have very seasonal food supplies, and very short infancy for they young. Humans have food supply year round, and secondly, the young take at least 12 years to reach maturity. In addition keep themselves sheltered from the worst of the weather. It makes little difference to the success of humans raising young whether the baby is born in March or September. For a deer, having a baby in September would be likely be fatal for the young

Humans can raise babies anytime and it takes so long to raise them that having them in spring isn't a particular advantage. Some predators like mountain lions can have offspring at any time but most carnivores time the birth of offspring to when there are the most young animals to eat. We seem to have come from a tropical ape, so we probably haven't had a mating season for many millions of years.

You would almost be better off to ask this in the anthropology section, of Yahoo Q&A.
Quiet frankly scientists have as many theories about why womens fertile times are hidden as there are stars in the sky.
If you believe in evolution a good reason that human females might have a hidden fertile time is to get males to protect and provide for them at ALL times.
If the males cannot tell when a female is "in season" and will become pregnant and carry on the males genes, the male needs to expend time and energy to ALWAYS feed and protect that female, if he wants to be sure the offspring are his. This also enabled women to be able to entice the men to stick around and help raise the offspring after it was born. Remember, even after weaning, a human child is completely dependant on the parents. If the woman can entice the male to stick around (she might be fertile again) and help entice the male to have a vested interest in the child, the offspring are much more likley to survive to adulthood.
Other female primates, like gorillas, will not resume sexual activity until their offspring is three or four years old. Male gorillas collect harems, of "wives" to give them more chances at passing on their genes.
Human females are able to entice just one male to stay with just one female, since her fertility is hidden, and she can always be sexually receptive.
Another theory is the hidden fertile times of the females allowed humans to live together in bands. If human females had an obvious heat cycle, of lets say the baboon, and developed a big swollen, bright red rear end, all the males would know that she was receptive. They would all hang around, and fight for the chance to breed with her (and then she would be on her own to raise the offspring). None of the males would be out hunting a bison for the tribe, instead they would all hang around, until the female was out of heat. Hidden fertility allows humans to band together.
Hidden fertility allows the women of the tribe to be better fed, is another theory. If women showed obvious signs of fertility, the men would fight over her, and share their food ONLY with her. They would not give food to non fertile females, or females with young....there would be no point....they wouldn't recieve sex in return.
Another theory is that it keeps the men at home, and linked to his mate. Unless she is obviously pregnant, he has no idea if she is fertile or not. If he goes off, and leaves his mate unguarded, the caveman Ugh, delivering the mastadon milk could take advantage of a lonely cavewoman. The only way to ensure the children are his is to be attentive, and keep away the other men, so they do not breed with his female.
Still yet another theory is so that women WILL mate with men.
Human infants are TITANIC in size compaired to other primates. A female gorilla weighs over 200 pounds...if she has a normal healthy baby, it weighs about 4 pounds. A normal child bearing human female is about 120 pounds. She has a 7-8 pound baby. The pain, and the risk to the human females life are very real. If she doesn't know when she's fertile, she cannot avoid sex during those times.
There are still other theories, but I supose that's enough to give you something to think about.

Many animals have to mate so that the offspring are born when food, water, shelter is available. If, for example, baby animals were born during the dry season of the savanna, there would not be enough food and water for it to survive. If young were born during the winter months is some regions, they would freeze so they are typically born in the spring.

Because there would be a massive revolt if we weren't allowed to have sex year round.
