Since there is no real atmosphere, just a low, thin collection of ionized gases, there is no real "weather". The surface temperature, however is extremely hot when you're on the sunny side, and extremely cold when you're on the shady side.
Mercury has two characteristics that make its surface temperature interesting. One is a highly elliptical orbit that takes the planet from 46 million km at perihelion to 70 million km at aphelion. That means the solar intensity varies from 4 times the intensity at Earth to over 10 times. The other aspect is that it rotates only about one and a half times per Mercury year. This makes a solar day on Mercury (sunrise to sunrise) apparently 156 Earth days long. A point that gets hammered by the maximum solar intensity will be in the frigid dark 88 Earth days later. The day side temperature can reach 700 Kelvins (about 430°C, or about 800° F.) Curiously, Venus is hotter at the surface than Mercury, even though it is farther from the Sun. The dense atmosphere of Venus holds in what little solar radiation makes it through the clouds, while Mercury efficiently radiates back to space. On the dark side, Mercury can be as low as 90 K (-183°C).

Mercury has almost no atmosphere and as a consequence does not have weather.
Hot and even more hot
The planet Mercury does not have weather patterns just wild temperatures.
Mercury has no atmosphere to speak of, and therefore it has no weather.
Yes. The usual snowfall is around 40-50 cm a year.
Mercury is the planet: there is no raw (or ripe) planet associated with it!
Mercury is a very hot planet. Mercury is the closest planet to the sun.
The planet Mercury does not have weather patterns just wild temperatures.
The weather of Mercury is burning hot!! Its very very hot!
Mercury has no atmosphere to speak of, and therefore it has no weather.
Mercury doesn't have weather because it doesn't have very much of an atmosphere. It does have days, nights and temperature changes though.
No, Mercury barely has an atmosphere and so it does not have any weather to speak of.
To get weather, you need an atmosphere. Mercury is the only planet without one.
Mercury is a planet.
Yes. The usual snowfall is around 40-50 cm a year.
Mercury is not a dwarf planet. It is a planet.
Mercury is itself a planet - it did not come from a planet!
It's very hot (being closest to the sun), and there is no atmosphere, so there are no clouds or rainstorms.
Mercury is the planet closest to the sun.
