Variability and space weather
The solar wind is responsible for the overall shape of Earth's magnetosphere, and fluctuations in its speed, density, direction, and entrained magnetic field strongly affect Earth's local space environment. For example, the levels of ionizing radiation and radio interference can vary by factors of hundreds to thousands; and the shape and location of the geopause (Earth's bow shock wave in the solar wind) can change by several Earth radii, exposing geosynchronous satellites to the direct solar wind. These phenomena are collectively called space weather.
Both the fast and slow solar wind can be interrupted by large, fast-moving bursts of plasma called interplanetary coronal mass ejections, or ICMEs. ICMEs are the interplanetary manifestation of solar coronal mass ejections, which are caused by release of magnetic energy at the Sun. ICMEs are often called "solar storms" or "space storms" in the popular media. They are sometimes, but not always, associated with solar flares, which are another manifestation of magnetic energy release at the Sun. ICMEs cause shock waves in the thin plasma of the heliosphere, launching electromagnetic waves and accelerating particles (mostly protons and electrons) to form showers of ionizing radiation) that precede the ICME.
When an ICME impacts the Earth's magnetosphere, it temporarily deforms the Earth's magnetic field, changing the direction of compass needles and inducing large electrical ground currents in Earth itself; this is called a geomagnetic storm and it is a global phenomenon. ICME impacts can induce magnetic reconnection in Earth's magnetotail (the midnight side of the magnetosphere); this launches protons and electrons downward toward Earth's atmosphere, where they form the aurora.
ICMES are not the only cause of space weather. Different patches on the Sun are known to give rise to slightly different speeds and densities of wind depending on local conditions. In isolation, each of these different wind streams would form a spiral with a slightly different angle, with fast-moving streams moving out more directly and slow-moving streams wrapping more around the Sun. Faster-moving streams tend to overtake slower streams that originate westward of them on the Sun, forming turbulent corotating interaction regions that give rise to wave motions and accelerated particles, and that affect Earth's magnetosphere in the same way as, but more gently than, ICMEs.

there IS weather believe it or not. The effects from the sun make it dangerous due to solar flares and other explosions. There's no air or pressure, but that doesn't stop the extreme climate that space has to offer. Astronauts need to be careful when walking in space as an explosion from the sun can easily kill them. One of the Apollo missions had to be terminated due to an explosion from the sun. I think that was 17.

Yes an no. We consider weather on earth as atmospheric conditions. There is no atmosphere in space, no. But, there is space weather, which is usually referring to solar activity. It is different, but affects many things in similar manners that like weather on earth, such as winds (solar winds), heat, and electricity (like lightening, but not).

If you're talking in terms of solar winds, magentic storms and the like, the answer is yes. Here is an interesting article:

It relies upon the place in area somewhat yet in maximum places it somewhat is going to likely be very chilly. often attaining absolute 0. The tension could somewhat kill you so which you're able to desire to placed on a spacesuit yet it somewhat is approximately it. On planets the climate could be diverse, there may be harsh winds or severe warmth. In some places in area the climatic situations are very resembling that in the process the international. the warmth and tension are merely top. It somewhat does count.

no 'cause weather is an atmospheric effect (airpressure, water condensation, ...)
without atmosphere --> no weather
However there is something like solar winds.
These are particles that are expulged by the sun.

There is no air or water like on earth but there is lots of moving dust, comets etc . . . so you might consider that space weather !

Certainly, it is just involves different elements than what we experience on Earth. Cosmic ray "showers", as well as meteor "showers". Radiation "rain" or "wind".

There are temperatures, but there is no wind or precipitation. In fact, there's no air, but the temperature is different in different places of the universe.

Yes... but not the same eas we have on earth.. Magnetic storms are frequent in space... for one type.
