Does SAD completely disappear in the summer?

I'm sure there are other people on the forum who can speak from experience, but I can give you some information from Norman Rosenthal's "Winter Blues" (an excellent reference book for SAD.)
Most saddies do recover, yes, though some have some "down" spells. These can be caused by a variety of things. I've heard that it helps to do a bit of light therapy if there's been a cloudy spell, even in the summer.
Some people are so severely depressed in winter that they don't fully recover in the summer. There's a case in point in Rosenthal's book -- but the good news is that when this patient had light therapy and antidepressants for the first time in the winter, her depression cleared completely in the summer.
Any particular reason for asking? :)

For some yes it is, though others end up needing both. It's something you might want to discuss with your doctor. There's a good chance that if you start an appropriate light therapy regime in the autumn, as soon as the first symptoms of SAD appear, and stick to the routine every day, increasing your light as the days darken -- then you might not need antidepressants. But light therapy alone isn't a complete cure for many so bear this in mind. If you are new to treating SAD then I think "Winter Blues" would be a very helpful book for you to read.

I'm sure it's the rotten summer of 2004 that's contributed to the severe SAD that I and many others are experiencing now. The summer before that was very sunny, wasn't it, and I don't remember having any problems at all the following winter. Let's pray, pray, pray that last summer was just an unfortunate blip and that we can all get that sun we need this time. Thanks for your comment Wee One; I've read that when the weather is bad in summer, a little light therapy can help, and I'm going to keep my visor handy.

Hi

I've noticed a definate connection between the weather and my SAD rather than the time of year. If we (I live in the land of midges and rain - the highlands of scotland) have a couldy summer I feel terrible, likewise if we have a brilliant summer I have to watch how much sunshine I get otherwise I go hyper. I have to wear sunglasses during really sunny spells to make sure I don't go off the rails. I don't know which is worse the depression from lack of sunlight or going hyper with too much sunlight.
