About this dashboard
A sailing weather dashboard focused on the things that matter on the water — wind & gusts, wind direction, waves and swell, fog risk, sky and precipitation, barometric pressure, tides and water temperature, and active marine advisories.
It opens on Monterey Bay by default, but you can pick and save any coastal spot with the location picker — the whole dashboard then follows that location. The page is a thin, cached proxy over public government feeds; it stores nothing about you on the server, and your saved locations live only in your own browser.
The three views
- Now
- Current conditions for the active location, plus a day/night-aware sun / moon / cloud / rain icon.
- Hourly
- An hour-by-hour table for the rest of the local day.
- Daily
- A 7-day outlook aggregated from the forecast (daily high/low, peak wind & gust, waves, and Beaufort force).
What each widget means
- Temperature
- Air temperature at the location. Switch °F / °C on the Settings page.
- Beaufort force (BF)
- The wind on the 0–12 Beaufort scale, with a short sailing note for the current force. The Hourly and Daily tables show this in the BF column, with each value written as F0–F12 (e.g. F4 is a moderate breeze).
- Weather icon
- A sun by day or moon by night, with cloud and rain overlays added as cloud cover and rain chance rise. Day vs. night is computed from local sunrise/sunset.
- Wind — Measured vs Forecast
- Forecast is the smoothed model wind from the forecast grid; Measured is the latest reading from a nearby buoy or shore station. They can differ because local funneling (e.g. a bay venturi) under-reports in the model. Use the dropdown to choose which station the measurement comes from. The compass shows the direction the wind is blowing toward.
- Waves
- Significant wave height and period, the locally generated wind wave, and the longer-travelling swell with its own direction compass.
- Rain chance
- Probability of precipitation for the current period.
- Cloud cover
- Sky cover as a percentage.
- Pressure
- Barometric pressure from the nearest reporting station, with a small sparkline of the recent trend (a falling barometer often precedes deteriorating weather).
- Humidity & Dewpoint
- Relative humidity and the dewpoint temperature.
- Fog risk
- Likely / Possible / Unlikely, derived from how close the air temperature is to the dewpoint — a small spread means fog is more likely.
- Tides & Water
- The next high/low tide, current water temperature, and a 48-hour hi/lo curve from the nearest tide-prediction station. Heights are relative to the MLLW datum. Use the dropdown to switch stations.
Choosing a location, units & text size
Click the location name in the header to open a map. Click or drag the pin to pick a
spot, give it a name, and save it — saved favorites persist in your browser
(localStorage) and the dashboard follows the active one.
The Settings page (gear icon in the header) holds the unit choices — temperature (°F / °C), wind speed (kts / mph), and wave height (ft / m) — plus a base text size for easier reading. All of these are saved in your browser and apply across the whole site.
Marine advisories
When the National Weather Service has an active marine advisory for the area — a Small Craft Advisory, Gale Warning, and the like — a color-coded banner appears above the tabs in every view.
Where the data comes from
- Forecast
- The National Weather Service gridpoint forecast (temperature, wind, waves/swell, sky cover, precip chance, humidity).
- Advisories
- NWS active alerts for the point, which resolves the relevant marine zone.
- Pressure & measured wind
- The nearest reporting NWS observation stations and NOAA NDBC buoys — the forecast grid carries no usable pressure, and measured wind comes from real instruments.
- Tides & water temperature
- NOAA CO-OPS Tides & Currents — tide predictions from the nearest reference station and water temperature from the nearest live sensor.
The server caches upstream responses for a short time so visitors don't each hammer the
government feeds, so values can be a few minutes old. Wave and swell fields exist only
for coastal marine grid points; at inland points they show --. This is
expected, not an error.
Privacy & cookies
- Cookies
- This dashboard sets no cookies and includes no analytics, advertising, or tracking scripts of its own.
- Saved locations
- Your saved locations and the active selection are stored only in your own browser
(
localStorage). They are never sent to or stored on the server, and clearing your browser data removes them. - The server
- A stateless proxy that keeps no per-user data — only a short-lived shared cache of the government feeds and anonymous, aggregate usage counts (no personal identifiers).
- Embedded third parties
- The maps and fonts are loaded from third parties — Windy, PredictWind, OpenStreetMap, and Google Fonts — which receive your IP address and may set their own cookies under their own privacy policies.
In short: nothing here identifies or tracks you. The only data tied to you (your saved spots) stays in your browser.
