Pacific Northwest & Alaska
Start with Washington, Oregon and northern Pacific waters; use Alaska’s dedicated zones for its much wider coast. Match the forecast to the actual operating area.

A practical starting point for checking the water, planning work, and finding the marine people you need—from Atlantic harbors to the Gulf, Pacific, Alaska, Hawaii and Great Lakes.

Four broad planning regions make the official forecast network easier to enter. Select a region, then choose your exact NWS coastal, offshore or Great Lakes zone.

California & Pacific South
Find California coastal and offshore zones, then verify local warnings and nearby observations. Hawaii has its own Pacific forecast areas rather than a mainland quadrant.
Find official marine zones ↗Northeast, Mid-Atlantic & Great Lakes
Choose the appropriate Atlantic nearshore or offshore zone—or a Great Lakes zone—then compare the forecast with local station conditions and active advisories.
Find official marine zones ↗Southeast & Gulf
Explore South Atlantic, Florida and Gulf waters by specific zone. Check tropical products and active warnings directly when relevant to the trip or worksite.

01 / Find your water
Zoom to your location
Use a coastal or Great Lakes point for the nearest National Weather Service forecast. For offshore passages, choose the correct marine zone and check its watches, warnings and advisories separately.
Coordinates stay in this browser until you open the NWS link. Location access is optional. A point on land may show a land forecast; always cross-check the adjacent marine zone for winds, waves and hazards.

Today through one month
A professional plan separates detailed short-range weather from longer-range probabilities. No credible monthly outlook gives a reliable day-by-day sea-state forecast.
Marine forecast & current conditions
Read your NWS marine zone for wind, seas and active hazards. Compare it with nearby NOAA station observations and tide predictions before a trip or job.
Coastal & Great Lakes zones ↗Detailed point forecast
Use the location tool above or NWS’s marine point-forecast map for available hourly and multi-day detail. Marine-zone periods and coverage vary by area.
Marine point forecasts ↗Pattern, not wave height
NOAA Climate Prediction Center maps show probabilities for above- or below-normal temperature and precipitation. They do not predict a specific day’s wind, waves or safe boating window.
6–10 day outlook ↗8–14 day outlook ↗
Climate outlook & tide dates
Use CPC’s monthly temperature and precipitation outlook for broad planning, plus NOAA tide predictions for date-specific high and low tides. Recheck short-range marine forecasts as the date approaches.

Safety note: This page is a planning directory, not a certified physical weather station, navigation instrument or real-time warning service. Verify timestamps, active advisories, local notices, charts and on-water conditions directly with official sources. Do not use a monthly outlook to make a go/no-go decision.

From the forecast to the right contact
1 · Check the conditions
Look at your exact water, a relevant station, tide stage and any active marine advisories.
2 · Plan the work
Use the outlook for tentative dockage, service, haul-out, charter or supply timing; confirm details as the date nears.
3 · Connect locally
Search marine businesses by service and place, or describe a specific need so participating businesses can respond.
