Had you experienced cool or hot temperatures earlier and now temperatures have moderated? Nighttime temperatures below 60F or above 75F can hamper fruiting. Also, if you had very hot daytime temperatures, such as 90F or above, that can cause blossoms to drop or pollen to become sterile, reducing fruit production until plants recover. Ideal daytime temps are between 70 and 80 (hot peppers can take about 5 degrees higher). Drought or other stress, too much nitrogen, or other factors can also discourage fruiting.
