June Temperatures

Preliminary data indicates that the statewide average temperature in June was 72.7°F, which is 0.6°F above the 1981-2010 mean value of 72.1°F (Figure 1). June 2018 was the 26th warmest June since 1895. While a large majority of the United States saw significantly above normal temperatures for June (Figure 2), Delaware’s temperatures were more consistent with temperature anomalies found across the
mid-Atlantic and New England.

June Precipitation

Delaware’s statewide precipitation for June 2018 averaged 3.62
inches, 0.11 inches below the 1981-2010 mean (Figure 3). However,
the year-to-date precipitation across Delaware continues to run above
normal, with precipitation during the first six months of the year
coming in as the 16th wettest since 1895, and the wettest since 2003,
mainly as a result of heavy precipitation during February and May.

Statewide Spatial Averages

Data from the Delaware Environmental Observing System (DEOS)
show that temperature (Figure 4) departures were generally small
and varied between positive and negative values across the State.
This pattern of departures is expected for a month with near normal
temperature conditions. Precipitation departures also varied greatly
from one location to another (Figure 5). This is due to the
“convective nature” of the precipitation during the summer months,
with most falling in thunderstorms that cover only a small area.
