They are wind-pollinated. The anthers will release the pollen when the conditions are right, (usually about 2pm West-USA time) when the day is at it's warmest and the air at it's driest. Pollen is not released when it rains as rain has a devastating affect on pollination - it simply wipes the pollen out of the sky.
