Mud flow 2006Edit
Since May 2006, more than 10,000 people in the Porong District have been displaced by the hot mud flowing from a natural gas well being drilled by Lapindo Brantas, an oil well company that is part of a conglomerate owned by Coordinating Minister for the People's Welfare Aburizal Bakrie. Gas and hot mud started spewing from the well on May 28, when the drill penetrated a layer of liquid sediment. Attempts to pump concrete down the well did not stop the flow. While some scientists have speculated that the earthquake that struck Yogyakarta on May 27, the day before the well erupted, may have cracked the ground, creating potential pathways for the mud to reach the surface, others have suggested that the drilling procedure was faulty by not using a casing. This is likely to be incorrect as technical papers on the subject showed that there were up to four sets of casing installed and cemented in the well. Some 50,000 cubic metres of hot mud were erupting every day as of August; in September, the amount increased to some 125,000 cubic metres daily. On September 26 barriers built to hold back the mud failed, resulting in the flooding of more villages. Gus Maksum, one of the thousands of Sidoarjo villagers displaced by the mud flow gives a detailed first-hand account of the first year of the disaster in his memoir Titanic Made By Lapindo. As of late September 2006 scientists are saying that the eruption may be a mud volcano forming, and may be impossible to stop.

Humidity is an important factor in determining how weather conditions feel to a person experiencing them. Hot and humid days feel even hotter than hot and dry days because the high level of water content in humid air discourages the evaporation of sweat from a person's skin.
When reading the graph below, keep in mind that the hottest part of the day tends to be the least humid, so the daily low (brown) traces are more relevant for understanding daytime comfort than the daily high (blue) traces, which typically occur during the night. Applying that observation, the least humid month of 2015 was October with an average daily low humidity of 40%, and the most humid month was April with an average daily low humidity of 64%.
But it is important to keep in mind that humidity does not tell the whole picture and the dew point is often a better measure of how comfortable a person will find a given set of weather conditions. Please see the next section for continued discussion of this point.
