It was raining when I got up this morning and by the time I was finished making coffee the rain had disappeared lol. With this being the first poem of the day that I am commenting on I think that is kinda fun. Even though I have read this twice and can see a few meanings in it besides just literal nature. I always love your poems but when you write short pieces I love them more because you have such a way with words, you always say sooooo much without really saying anything at all. Great write, as always.

My favorite line:
smiling warmly with soft air,

Again I am sad because this was down voted. Shame. Shame.

With any haiku you need a set time of day, year anything like that. Summer is the one you picked and using it sets up the rest of the poem or should. The use of windswept and soft work well to the imagery of the poem. It tells me it's a hot or humid day which is normal for summer. (Of course). You don't normally think of nature with emotions, but using happy I liked. The last line is my favorite not for its in depth but for its wording. The imagery tells me that there was rain or a storm and now there is sunshine which works well with happy. People think of sunshine as a happy time in their lives. :). Well written.

Very nice construction, flow, idea and meaning.
