Ratings represent risk relative to the continuous United States. 100 is the highest risk for the hazard and 1 is the lowest for the U.S., but does not indicate no risk. Flood and fire are rated based on the buildings in Galveston exposed to these hazards. See hazard sections below and check your address for details.

Of 33 census tracts in Galveston, TX, there are 33 where more than half of buildings have significant risk from storm surge, high tide flooding, surface (pluvial) flooding, and riverine (fluvial) flooding.Property owners can check a specific address for flood risk including FEMA flood zone, then take steps to reduce their vulnerability to flooding damage.
Climate change is increasing inland and coastal flooding risk due to sea level rise and increasing chances of extreme precipitation. See more information on flooding risk.
The number of the hottest days in Galveston is projected to keep increasing.
In a typical year between 1985-2005, people in Galveston, TX experienced about 7 days above 92.8ºF in a year. By 2050, people in Galveston are projected to experience an average of about 42 days per year over 92.8ºF.
Climate change is increasing the frequency and intensity of heat waves, even in places with cooler average temperatures. See more information on heat risk. Everyone can take steps to reduce their risks from extreme heat.
The amount of precipitation during the most extreme days in Galveston is projected to remain about the same through 2050.
An extreme storm for Galveston, TX is a 48-hour rainfall total greater than 1.1 inches. Historically, about 19.0" of rain (or the equivalent in snow) fell over about 10 storms each year. By 2050, about 19.4" of rain are projected over about 10 storms each year. The annual precipitation in Galveston, TX is projected to decrease from about 40.4" to about 39.9".
Extreme precipitation in any form can pose significant risks. Climate change increases the potential for extreme rainfall or snowfall because warmer air can hold more water vapor. See more information on storm risk. Property owners can take steps to reduce their risks from extreme precipitation.
The recent average water stress in Galveston is significant and projected to increase through 2050.
The West Galveston Bay watershed, which contains Galveston, TX, has experienced 495 weeks (43% of weeks) since 2000 with some of its area in drought of any level, and 71 weeks (6% of weeks) since 2000 with some of its area in Extreme or Exceptional drought. Source: National Drought Monitor.
Climate change is increasing the risk of drought. Water stress (the ratio of water demand to supply) depends on how water utilities source water and their plans to adapt to climate change. Property owners can also take steps to reduce their risks from drought.
The risk on the most dangerous fire weather days in Galveston is low. The number of these days per year is expected to increase through 2050.
Of 33 census tracts in Galveston, TX, there are 13 where more than a quarter of buildings have significant fire risk, and 5 where more than half of buildings have significant fire risk. Property owners can take steps to mitigate their risks from wildfires.
Fire risk depends on proximity to vegation: densely developed urban areas have a much lower risk of burning than areas adjacent to wildland. Climate change increases risks from wildfire by creating hotter, drier conditions for fires to spread. ClimateCheck ratings of fire risk are based on projected weather conditions and U.S. Forest Service models simulating fire behavior.
Mitigating climate change, by eliminating our emissions into the atmosphere and reducing our strain on the environment, and adapting to our changing planet are both vital to our well-being.
