Symptoms of a new era or...?

Cloudy summers, are something strange and new for citizens of a city like Tehran.
Actually, the reason of this kind of summer may be two.
One: just a passing weak side effect from "El Nino" and "La Nina", which brought the humid air from indian ocean and arabian sea to north, and when the humid air hits the cold heights of Zagros And Alborz,it turns to cloud, and covers cities which are nearby, these clouds are protecting the land from sun, so summer turn cooler but more humid.

Two: the reason of clouds appearing is the as above, but it may be an effect from Global Weather Changing, if we count this as a true fact(which we have some good records to believe it!) we can watch for a new weather era for summers, and as this year, it's possible to see cyclone hitting southeast even. and why all these things happen? the reason is that sea surface temperature is higher(El Nino) or lower(La Nina) than normal, both these facts, have the potential to creat cyclones and Tropical storms in indian ocean and even sometimes in arabian sea(like cyclone Gonu), when this happens, these system's after effects, covers more areas, so the humid air is strong enough to come to the dry lands of north(Arabia and Iran Deserts), this doesn;t mean that we are going to have this kind of summers from now in every year, but it means that the number of these kind summers is on rise.

I'm watching carefully to see if it's going to has effects on winters too or not.

in the map above, you can see the way of humid air coming from southeast to northwest with blue lines, and zagros and alborz mounts which make it becomes cloudy with red line.

Monsoon rains to heat southeast

Once again as you can see in this image a heavy monsoon storm ( not as strong as a tropical storm and more like a tropical depression ) is nearing southeast shore of Iran, heavy showers and flooding is possible mostly in southern Sistan-Balouchestan , Hormozgan & south of Kerman provinces.
Also there is slight chance of minor showers or thunderstorms in mountain nearby cities, like west to northwest to north and northeast.
