The North (Irish) Channel has shorter and less tidal windows than those of the English Channel sometimes with only five days per month when an channel swim crossing can take place.
Strong tidal currents can make it impossible for a swimmer under 3k/h speed to successfully cross however there have been several successful crossings with a swim speed lower than 3k/h.
The weather on the North (Irish) Channel can change quite quickly regardless of what the weather forecasts have predicted.
Here is some data from the North (Irish) Channel Weather of previous years to help your research.
