Who am I
I'm Scott, I grew up in Bermuda and have spent most of my life on the island. Like every Bermudian, weather isn't just small talk — it directly shapes daily life on the island in ways that outsiders rarely appreciate.
Most weather websites are built in the United States with a US audience in mind. They give you temperature, a chance of rain, and maybe a radar loop. But for Bermudians, that's only part of the picture. I built this site to fill in the gaps.
The Tank Rain Problem
If you're not from Bermuda, you may not know this: Bermuda has no rivers, streams, or natural surface freshwater supply. The island relies on three sources of fresh water — and rain is the most personal of them all.
Roof catchment ("the tank") is the oldest and most culturally ingrained. By law, every building must harvest rainwater. Water runs off white-painted limestone rooftop steps and down into an underground cistern — what we call the tank. When it rains, your tank fills. When it doesn't, your tank level drops and you start watching the sky.
Reverse osmosis desalination now supplements the supply — six plants around the island produce roughly 13,500 cubic metres of desalinated water per day, accounting for about a quarter of Bermuda's total consumption.
A freshwater lens sits underground, where a thin layer of fresh groundwater floats on top of heavier saltwater inside Bermuda's porous limestone. Over 3,000 households tap into this lens via private wells, though the water can be slightly brackish and is used mainly for non-potable purposes like flushing toilets and watering gardens.
Even with desalination and the lens, tank rain still matters deeply. For Bermudians, a good rain isn't just nice — it can mean the difference between a full tank and calling the water truck. Knowing when it will rain, how much, and whether tomorrow will be dry enough to catch clean water is genuinely important. American weather apps simply don't think about this. Tankrain BDA does.
That's why rainfall data, hourly precipitation forecasts, and daily rain chance are front and centre here — not buried three taps deep in a menu.
What Makes Bermuda's Weather Unique
Rainfall & Tank Levels
Bermuda relies on rainwater collection. Real precipitation timing and accumulation data matters more here than anywhere else.
Atlantic Storm Tracking
Bermuda sits right in the middle of the Atlantic hurricane belt. Knowing what's forming, where it's headed, and how far away it is can be life-saving.
Tides & Ocean Conditions
Boating, fishing, diving, and beach life are part of everyday Bermuda. Accurate tides and wave data are essential, not a bonus feature.
Wind Speed & Direction
Wind on a small island surrounded by open ocean hits differently. Sailors, cyclists, and anyone spending time outdoors needs this at a glance.
Data Sources
All data displayed on Tankrain BDA comes from trusted, free public sources:
Open-Meteo provides weather and marine forecasts directly from global weather models. NOAA CO-OPS supplies tide predictions for St. Georges Harbour (Station 2695540). NOAA NHC feeds the Atlantic storm tracker with live tropical system data. NOAA NDBC Buoy 41049 (South Bermuda) gives real-time ocean observations right off the coast.
The site runs entirely in your browser, fetching live data directly from these sources.
