Understanding Your Tide Alerts

A plain-language guide to creating an account, setting up notifications, and reading what comes back — for the tide and weather stations run by volunteers and academic partners along the coast.

01 Creating an Account

An account is what lets the station send alerts to your email or phone when conditions you care about are met — a certain tide height, an approaching high tide, unusual wind, and so on. Setting one up takes a minute.

  1. Open the registration form from the station's home page and choose "Register New User."
  2. Enter your email address and choose a password.
  3. Submit the form. The station sends a confirmation email to the address you entered.
  4. Open that email and click the confirmation link. This proves the email address is really yours before any alerts are sent to it.
Act quickly

The confirmation link is only valid for 10 minutes after you register. If you don't click it in time, the registration attempt expires and you'll need to fill out the form again. This isn't a bug — it's a deliberate limit so that unfinished, unconfirmed sign-ups don't pile up in the system indefinitely.

02 Logging In

There isn't a separate "Login" button — the same form handles logging in, changing your password, and registering, all through one set of radio buttons. To log in, enter your email and password and leave "Manage Alerts" selected (it's the option already selected by default), then submit the form.

A successful login takes you to the alert request form described below, with your email address already filled in. The other fields always start blank, regardless of what you've saved before — see Checking Your Settings Without Changing Them for how to actually view what's currently on file.

If your email and password don't match what's on file, the form will let you know rather than silently failing — double-check for typos, or use the password reset option covered in Managing Your Account.

03 How Your Information Is Protected

This tide station is a free service, kept running by volunteers and academic partners — not a company, and not something that runs on advertising or data. Here's what that means in practice, and how your information is actually handled behind the scenes.

Our commitment

Your email address and phone number are used only to deliver the alerts you ask for. They are never shared, sold, or used for anything else — not by us, and not by anyone we work with.

Your email and phone number

Before your email address or phone number is ever saved, it's run through an encryption process that scrambles it into unreadable text. That scrambled version is the only thing stored. It can only be unscrambled by the station's own software, at the moment it actually needs to send you an alert — not by browsing the database directly.

Your password

Your password is treated even more carefully: it isn't stored at all, not even in scrambled form. Instead, the system stores a one-way mathematical fingerprint of it. When you log in, your typed password is put through the same process and the two fingerprints are compared. If they match, you're in. There's no step in this process that reveals your actual password to anyone, including the people who maintain this station.

04 Managing Your Account

Changing your password

From the login form, enter your email and current password, choose "Change Password," and submit. You'll land on a second page asking only for your new password (entered twice, to confirm it) — your current password carries over automatically from the first screen, so you won't need to type it again. If it didn't match what's on file, the change won't go through.

Forgot your password?

Choose "Forgot Password" and enter your email address. If it matches an account on file, you'll receive an email with a link to set a new password. As with registration, this link is only valid for 10 minutes — if it expires, just request a new one.

05 The Alert Request Form

Once logged in, you'll see one form covering everything the station can watch on your behalf. You don't need to fill in every field — set up only the alerts that are useful to you, and leave the rest blank.

Phone number format

If you'd like text alerts, enter your phone number as 10 digits only — no dashes, spaces, or parentheses (for example, 8435555555, not 843-555-5555). The form will reject other formats.

The six kinds of alerts

🌊 Tide Level

Notify me each time the actual measured tide crosses a height you set, in feet — once as it rises past that level, and again as it falls back through it.

🔄 Tidal Variation

Notify me when the real tide differs from what NOAA predicted — by more than a set amount, either higher or lower than expected. Useful for catching storm surge or other unusual conditions.

⏰ Event Notice

Give me advance warning — a set number of minutes ahead of time — before the next high or low tide, but only if that tide is expected to exceed a threshold you choose.

🌡 Air Temperature

Notify me when the air temperature reaches a value you set, in degrees Fahrenheit.

🌊 Water Temperature

Notify me when the coastal water temperature reaches a value you set.

💨 Wind Speed

Notify me when wind speed reaches a value you set — optionally, only when it's blowing from a particular direction.

Options that apply to most alerts

Daylight Only

Check this box if you only want to be notified when the condition occurs during daylight hours. Handy if you'd rather not get a 3 a.m. text about something you can't act on until morning anyway.

Enable

Turns this particular alert on. This is selected by default whenever you set values for an alert.

Disable

Turns the alert off temporarily, without erasing the threshold you've already set. Choose this if you want a break without having to re-enter everything later.

Delete

Removes this alert entirely. Unlike Disable, there's nothing left to turn back on afterward — you'd need to set it up again from scratch.

Pausing everything at once

Near the bottom of the form, three options let you control all of your alerts together, without touching your individual settings:

Suspend All

Pause every alert you have — useful if you're traveling or simply want quiet for a while. Nothing is deleted; your settings are all still there when you come back.

Resume All

Turn everything back on after a suspension.

Clear Resume/Suspend

Reset this master switch without changing anything else — used only in unusual cases.

06 Reading Your Confirmation Page

Every time you submit the form — whether you're changing something or not — you'll land on a page titled "Alert Database Entries" for your account. This is a straightforward table showing exactly what's currently saved: your phone number (if provided), each alert's threshold, whether it's enabled, and its Daylight Only status.

Think of it as a receipt: confirmation that the form did what you expected, and a quick reference for what's actually active on your account right now.

Example: Alert Database Entries for you@example.com
Phone Nbr Tide Ena Day Air Ena Water Ena Wind Ena
843‑555‑5555 9.5 ft Yes No 85°F Yes No 20 mph Yes

07 Checking Your Settings Without Changing Them

Want to see what you currently have set up, without risking a change to any of it? Log in, leave every field on the form completely blank, and submit it as-is.

Good to know

A blank field is always treated as "leave this alone," never as "clear this." So submitting a totally empty form makes no changes at all — it simply takes you straight to your confirmation page, showing your current settings exactly as they stand. It's the fastest way to check what's active on your account.

08 Getting Help

If something isn't working as described here — a confirmation email never arrives, a login that should work doesn't, or anything else looks wrong — reach out to [email protected]. Since this station is run by volunteers, please allow some time for a reply.
