We will be in Murren in mid-June, so I wouldn't think it would be much different weather-wise than it is now. Checking weather.com, the high temps the last few days have been low to high 30's and the low's have been as low as 21 F. As we need to start packing soon, should we expect similar weather? If so, it sure makes it tough to pack lightly given our other bases in Beaune, Colmar, and Lucerne. I've read the entries of many others traveling there in May...has that been your experience? Thanks!
I don't know how accurately you have been receiving Muerren (remember the umlaut or extra e to have the right place) but when I was there just a week ago I was in shirtsleeves and in the sun it was lovely.
I didn't record the temperature but I would guess it was in the mid to low teens or better - C.
Whenever I have been there in June it has either rained or misted or been sunny. When sunny it has been shirt sleeves, but if going up a peak you will need a coat. If going Trummelbaching you will need a waterproof.
If it is raining you will need at least a waterproof shell. Think layers.
Nights cooler than days when it is dark.
search weather underground for trends and reasonable predictions and take with a grain of salt - you will be in the mountains you know...

Here's the rule with Alpine weather... there are no rules, except that on average, it will be colder in winter than summer. I've personally witnessed snow falling, at least at the upper altitudes, in every month except August. Some years, winter leaves by late-April, early-May, and then you see no sign of it again until the following autumn. Other years, you get fluctuating winter-spring tempertaures until summer finally takes over in mid-late June or even July (like this year). And sometimes, like last year, winter mainatins it's icy grip all the way into June or even July.
So, if you're looking for re-assurance that the sun will shine brightly and it will be warm when you arrive... sorry, can't give it. Prepare for a variety of weather conditions, budget enough time, and hope for the best.
The previous posters have pretty much covered it but it's really hard to say with any weather, let alone Alpine weather. June can be very up and down. I was there early last June and it was beautiful, sunny weather, the wildflowers were blooming, it was glorious. But two days before there had been enough snow that we couldn't hike the Kleine Scheidegg trail. You just never know. Layer, layer, layer is the best answer. No need to bring a winter coat and boots. Just plenty of layers.
Typical? There's nothing really typical about the weather in the Alps. As with Nigel, we too have been in Muerren in the first days of June a few years ago. We experienced the exact same type of weather. Warm and comfortable. Wildflowers were in bloom in the Alps and the farmers were walking their cows through the towns in the morning up to higher summer pastures. Fantastic.
I was exactly in your position this time last year as we were preparing for our mid June trip. I saw the forecasts and decided to pack a light coat. BIG MISTAKE!! When we got there, for some reason, despite what I thought were very reliable forecasts on reputable sites, we were pleasantly surprised to find the temperatures 10-15 degrees higher than we were expecting. We wore the jacket the first hour of day one and not at all after that. We hiked between Gimmewald and Murren and did the other side too. If I had to do it over again, I would not have brought the jackets and would have brought another long sleeve shirt to wear as a extra layer over a short sleeve shirt which I could take off as the day gets hotter and the body warms up from the hiking. Good Luck!!
I just returned from Murren. Like the others recommend, layers are the best solution. I had 3 days that were near perfect for being outdoors - cool (55 - 60F) mornings and warm afternoons. The temps vary significantly based on altitude. The Lauterbrennen Valley was in the 70s, while Murren was easily 10 - 15 degrees cooler at the same time, being higher up. The Schilton and Jungfraujoch were below freezing even midday - coat and fleece required to stay warm !
Have fun!
As a rule of thumb, every 1000 ft increase in altitude (~300 meters) will mean about 3 degrees F. cooler. This can be significant if you're taking a cog railway from, say, 5000 ft to 12,000 feet. This doesn't even discuss the effect of changes in wind velocity in the mountains.
