Onthe problem
“90%” is not a plan
It only means rain touches your city at some point. Five minutes at dawn counts. It says nothing about your afternoon.
One number, ten miles
The bay side and the freeway side genuinely get different storms. Your app averages them into fiction.
Summer storms are punctual
They fire after lunch and die by dinner, most days. Show that shape and the day becomes plannable.
GulfLine keeps what other apps throw away — and tells you the truth when the honest answer is “50/50.”
made for actual plans
GulfLine tracks lightning by satellite and applies your pool’s actual rule — closed 30 minutes after a strike within 10 miles, or whatever your pool enforces. If our feed hiccups we say “unknown,” never a false all-clear.
Go, risky, or pick another window — with the reason spelled out. Not a percentage you have to interpret while your brisket waits.
Odds of staying dry for the next 45 minutes, whether lightning is anywhere near, and honest heat guidance for being out in the open.
League City is ten miles wide and the bay breeze knows it. GulfLine forecasts your side of town — because one number for the whole city is how plans die.
everything in the app
The verdict on top is the point. Underneath it is a full Gulf Coast weather app — every number it needs to be sure, and none of the theater.
Hour-by-hour temps and rain odds, plus seven days of highs and lows — with the afternoon storm window drawn where it actually lands.
Wind and gusts, humidity, dew point, the UV index, and air quality — the numbers that decide whether “84°” is pleasant or brutal.
Tide highs and lows, water temperature, wave height and period, and marine wind — from the nearest NOAA tide station and buoy.
Animated radar with live satellite lightning strikes plotted on top, so you know where it’s raining and where it’s actually dangerous.
Sunrise, sunset, golden hour, and the moon phase — because “before dark” is a real deadline out on the cart.
Check back and GulfLine tells you what shifted since last time — storms pulled an hour earlier, rain odds dropped — not just a fresh set of numbers.
Lightning approaching, the pool’s all-clear, rain within the hour, severe alerts. You pick which ones. Nothing else buzzes.
Today, the week, the Can-I verdict, and pool status as widgets in the sky’s own colors — plus a live countdown on the lock screen while the pool waits out a strike.
Star the places you actually go for a verdict at a glance, and drop a plain answer straight into the group chat when someone asks.
Just ask
Ask in plain words, get a plain answer — with the reason and how confident to be. Every number comes from the forecast engine. The AI never makes one up.
