Allergic reactions are cumulative. When pollen counts are high, mold counts are high and you spend a lot of time outside, you are going to have a reaction to your cats, too.
If you can manage your seasonal allergies, the cats shouldn't be a problem, but it is not unusual for allergies to get worse after you are exposed for a few years to a trigger. You might want to think about having fewer cats in the future.
You can also revise your surroundings at home to minimize your allergies - get rid of curtains in favor of blinds, get rid of carpets, choose leather over fabric for upholstery, get better filters on your home A/C, don't open windows during high pollen times.
