72° on Nov. 11, 1999, the hottest reading for this week of the year since 1993. Next is 72° in 2001.
East Moriches’s center stands about 30 ft above sea level. Within three miles the land runs from 0 ft to 200 ft, a difference of 200 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Bald Hill, about 290 ft, 5 miles north-northeast.
Under the town center the state geologic map shows Monmouth Group, Matawan Group and Magothy Formation (clay, sand, gravel), from the Late Cretaceous, 66 to 100 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, sand, gravel. Age: Late Cretaceous, 66 to 100 million years old. About 14 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
Rain that falls on East Moriches runs straight into Long Island Sound and the Atlantic Ocean.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of East Moriches; river miles along the main stem, rounded.
East Moriches has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 21° in January. About 50 inches of rain fall in a normal year.
