Population over time
2 figuresHamler grew from 576 to 600 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.
| Year | People | Change |

K., C.R. Neiswander, Claud Revere Neiswander and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.

Each account below is quoted exactly as the forecast office filed it, from the NOAA Storm Events Database, and each date opens the federal record of that event.
| When | Event | Place named | Harm | What the report says |
|---|---|---|---|---|
| September 1994 | Hail | Hamler | $500,000 | Near Holgate,Large hail, driven by strong winds, broke windows and damaged siding, roofs, and cars. Crops were destroyed. |
| June 2025 | Thunderstorm Wind | Hamler | $20,000 | Photos of various large branches down. Appears to be some siding damage to a home. |
| June 2006 | Thunderstorm Wind | Hamler | $2,000 | Several large trees were blown down. A barn door was also blown in. |
| July 1997 | Thunderstorm Wind | Hamler | $2,000 | no account filed |
| September 2017 | Thunderstorm Wind | Hamler | - | The public reported a power line was blown down across a CSX crossing gate, preventing the gate from properly functioning. |
| July 2013 | Thunderstorm Wind | Hamler | - | A trained spotter measured a 64 mph wind gust. Tree limbs in excess of eight inches were blown down by the strong winds. |
| June 2013 | Thunderstorm Wind | Hamler | - | Widespread tree and tree limb damage was noted in and around the town of Hamler by NWS officials while conducting surveys of tornado damage in the area. All damage within the town of Hamler was the result of straight line winds. |
| June 2013 | Thunderstorm Wind | Hamler | - | A NWS storm survey of damage at a farm indicated a combination of the remnant circulation of a tornado to the southwest of the site, as well as an anchoring failure, resulted in the collapse of a grain leg collapse and damage to several empty grain bins. The grain leg was anchored by a three point system, with the northeast side of the leg being unanchored. As the strong winds impacted an anchor on the southwest side, the leg began to buckle and shift, causing the bending of a large I-beam and the uplift of a cement block where an anchor was set to the northwest of the leg. The grain leg twisted and collapsed onto several bins. Given the failure of the anchoring, winds are estimated at around 80 mph. |
| June 2013 | Tornado (EF1) | Hamler | - | A NWS survey of damage north of Hamler indicated a circulation quickly intensified and touched down onto a barn, destroying it and throwing the debris to the northeast for nearly a half mile (DI: SBO DI: 6). Several large trees in the immediate area were snapped. An adjacent soybean field indicated a convergent wind pattern which continued towards a small grove of trees where the tornado dissipated. The maximum width was 50 yards with maximum wind speeds estimated at 95 mph. |
| May 2012 | Thunderstorm Wind | Hamler | - | County dispatch reported a few trees down in town of unknown size. |
| August 2011 | Thunderstorm Wind | Hamler | - | Emergency management officials reported a few tree limbs and power poles down. |

| November 2002 | Thunderstorm Wind | Hamler | - | Emergency management reported a train was derailed by high winds estimated to be near 80 mph. This wind was likely downburst winds from the collapse of the parent supercell that produce a tornado farther west in Henry minutes earlier. |
| April 2000 | Flood | Hamler | - | Minor street flooding. |
| April 1995 | Thunderstorm Wind | Hamler | - | Winds to 70 mph were reported. Several trees were downed. |
