Reading the calendar: ↑ moonrise and ↓ moonset are local times. Stars are the solunar rating; “c” is the tide coefficient (20–120). Moon overhead and underfoot times are the major feeding periods, and moonrise and moonset are the minor ones; see each day on the tide pages.
Forecasts, alerts and marine forecasts: National Weather Service. Current conditions: NWS observations and NOAA tide-station sensors. Map stations: Iowa Environmental Mesonet (airports), NOAA CO-OPS, NOAA NDBC. Radar: NEXRAD via IEM. Satellite: GOES-East via NASA GIBS. Tropical: National Hurricane Center. Moon and sun times are calculated for this location. Forecast grid updated Sat 11:15 AM.
