Josephine, there's a spectrum of directional patterns: omni - wide cardioid - cardioid - supercardioid - hypercardioid - figure-8 (see attached drawing which I made for one of the manufacturers); a microphone can be anywhere along this line, not only at the well-known "stopping points," and many microphones have different patterns at different frequencies for better or for worse. These patterns derive from two contrasting operating principles. Omni and figure-8 are the two extremes, and everything else in between is some mixture of those two.
The closer you get to the omni end of the scale, the more immunity you have from wind noise, handling noise and physical vibration, proximity effect, and "popping" due to consonants when you close-mike a vocalist or a person speaking. Conversely, the closer you get to the figure-8 end of the spectrum the more potential difficulty you can have with these things, though you get other benefits (e.g. omnis are sitting ducks for diffuse low-frequency environmental noise such as "room rumble" while figure-8s reject it to an astonishing degree).
Your so-called hypercardioids very likely are more like supercardioids in actual fact, but they're still somewhat closer to being figure-8s than cardioids are, and therefore somewhat more sensitive to wind noise, all other factors being equal. However, all other factors are not always equal, and the difference may be just 3 to 4 dB when you'd like it to be 20 dB.
So your windscreens (and the strength of the wind itself) will make more of a difference than the difference between cardioid and supercardioid will make a difference, if you can follow my syntax.
