Hi Karizzel -
That should be a good time to visit the falls.
Please not that early June is still the last part of Winter at high altitudes. For example, the high mountain pass roads may not open until as late as mid June. My hotel planned for Wengen does not open for the season until June 3. High trails may still be blocked y snow in early June. So, if you plan to go to high altitude regions, the time that you go in June can be important.
Since the snow melt for the majority of the snow feeding the Rhine is nearinng the end of the maximum flow, and the falls will still be feeling the effect.
The difference betwen early June and late June at hig altitudes is quite significant.
At lower altitudes, such as near Lake Constance (the Bodensee) or the major cities, the weather is much warmer, and early May is already Spring.
