Proper blood rain, where the rain actually appears red, is relatively rare because you'd need red dust/particles in fairly high concentrations in the rain. Documented cases are few and far between.
Blood rains occur so rarely (typically only a few times a year in Europe, and less frequently than that in the U.S. and Canada) that the micronutrient boost they'll get isn't typically cause for concern.
Blood rain fell on Apulia on 7 March 1803, and it was then believed that the rain was caused by the explosion of Italy's volcanoes Mount Vesuvius or Etna, or that it was due to the transport of matter coming from the sea floor and raised by vapor.
A recent study by Indian and Austrian scientists has led to the discovery of the cause of the 'Blood Rain' phenomenon to be dispersal of spores of micro algae. Since 1896, reports have been coming in of sporadic instances of red coloured rain over parts of Kerala and Sri Lanka. The latest one was in 2013 over Kerala.
Notes: Sirocco is a warm, dry and dust laden local wind which blows in northerly direction from Sahara desert over North Africa as a dry wind and picks up moisture as it crosses the Mediterranean. Since they carry red dust over Sahara, the rainfall which they cause is called blood rain sometimes.
“'Animal rain' is a real weather phenomenon that happens when small animals get swept up in waterspouts or updrafts, and then fall to Earth with raindrops,” according to National Geographic. “Reported rains of bats, fish, snakes, birds, frogs, and jellies stretch back for centuries.”
The lluvia de peces ( lit. 'rain of fish'), also known as aguacero de pescado ( lit. 'downpour of fish'), is a phenomenon that has been occurring yearly for more than a century in Yoro, Honduras, in which fish are said to fall from the sky. It occurs up to four times in a year.
The Kerala red rain phenomenon was a blood rain event that occurred in Wayanad district region of Malabar on Monday, 15 July 1957 and the colour subsequently turned yellow and also 25 July to 23 September 2001, when heavy downpours of red-coloured rain fell sporadically on the southern Indian state of Kerala, staining ...
A red rainfall advisory is issued when downpours constitute an emergency. This is raised when observed rainfall is more than 30 mm within one hour or if rainfall has continued for the past three hours and is more than 65 mm. When PAGASA raises a Red warning, communities should be prepared to respond.
On June 7, 2005, thousands of frogs rained on Odzaci, a small town in northwestern Serbia. Climatologist Slavisa Ignjatovic described the phenomenon as “not very unusual” because the strong winds that accompanied the storm could have easily picked up the frogs.
The song is part of the band's third studio album, the 1986 record Reign in Blood. Along with being the most popular Slayer song among all their material, “Raining Blood” is truly one of the most popular songs in all of heavy metal history.

Written by Jeff Hanneman and Kerry King for the 1986 studio album Reign in Blood, the song's religious concept is about overthrowing Heaven. A sample from "Raining Blood", where the core riff comes into play after a thirty second introduction.
The Met Office points out that this is when red coloured dust or particles in high concentration mix with rain, turning the droplets into an orangey shade. It's scientifically known as wet deposition, but more commonly known as “blood rain”.
Colored rains occur when raindrops fall through dust plumes. Heavier rainstorms usually wash dust away before it is readily apparent, but brief, light showers can leave noticeable color across the landscape. Red rains only occur if dust particles contain enough iron oxide.
Rain hides human scent, but it also washes away blood trails.
Early in the morning on July 25, 2001, the state of Kerala, India, began to experience one of the strangest phenomena in all of meteorological sci- ence—red rain and hail. Red rainwater covered a geographic area of 450 150 km.
Fish don't usually fall from the sky, but this unusual meteorological phenomenon is possible although rare. The best explanation for this odd occurrence is that strong air disturbances, such as tornadoes, can lift water and fish up into the air. Then, the tornado can carry them for some distance.
Originally Answered: How do they make it rain in the movies? Most film productions use a device called a rain curtain (or several in tandem) along with fans and low lighting to create the illusion that it is raining.
During his studies, Aburto witnessed the unique courtship behavior of the bigeye trevally. He saw that large groups of the fish swim quickly together and around one another at high speeds. This creates a moving, swirling column of fish that can only be described as a fish tornado.
“Animal rain is a phenomenon that occurs when small water animals like frogs, crabs, and small fish are swept up in waterspouts or drafts that occur on the surface of the earth.
Arguably the rarest type of precipitation on our list, ice crystals are a meteorological phenomenon that you'll only see in very cold climates.
The acid rain on Venus is caused by the reaction of sulphur dioxide and water in the planet's atmosphere. Despite being many times more corrosive than the most acidic rain on Earth, Venusian rainstorms are not a significant contributor to surface erosion.
While useful for many things, rainwater is not as pure as you might think, so you cannot assume it is safe to drink. Rain can wash different types of contaminants into the water you collect (for example, bird poop on your roof could end up in your water barrel or tank).
