The OP just asked a question and he's had answer from VJW and I'll give him another answer. The FOs at my base are also hovering around the 90-100 hour mark for May, June & July.
Lord Spandex - for many (myself included five years ago) Ryanair was one of only a few options and financially it has worked out far better than if I'd gone anywhere else. I knew the risks with no guaranteed hours - we all do. But we don't need to be lectured about it on here. If the OP asked "Do you think coming here was a good idea? Please discuss" we would welcome your views but why do you come on here telling people to man up or clear off? It's just unnecessarily condescending.
End of rant. In answer to the OP - yes it looks like you're a little unlucky. I had quiet summer months when I was an FO too but over the whole year is what counts. Expect somewhere between 700 and 800.
