Everything a cyclist needs to know at a glance.

🗓️

Seven-Day Hourly Forecast

The full forecast in one view — every hour across seven days, with six metrics per hour, all color-coded. Temperature, rain, wind, air quality, UV, and solar heat gain. No daily summaries to guess from, no tapping between screens. Scroll down through the week; the column headers stay fixed so you always know what you're looking at.

Forecast cards are split at sunrise and sunset, so the visual transition between day and night conditions is immediate. Sunrise and sunset times are shown at each boundary.

Three Temperature Modes

The temperature column header is a button. Tap it to cycle between three views:

Real — the actual air temperature. Useful as a reference point.

Shade — apparent (feels-like) temperature accounting for wind chill and humidity. This is what it feels like riding in a sheltered area or under tree cover. A 59°F day with a 19 mph headwind feels like 48°F in the shade.

Sun — Shade temperature plus a solar heat gain offset. This is what it feels like riding fully exposed in direct sun. On a sunny 72°F afternoon the Sun reading can be 10–15°F warmer than Shade — the difference between comfortable and overheating.

Your preference persists across launches but stays one tap away.


☀️

Solar Heat Gain Index

Cyclists spend long periods exposed to direct radiation in a way that pedestrians and drivers don't. Solar Heat Gain Index (SHGI) measures that impact on a 0–10 scale, derived from direct and diffuse solar radiation data corrected for forecasted cloud coverage. It appears as its own column in the forecast.

Color coding runs green → yellow → orange → red → purple as intensity increases. The Sun temperature mode uses the SHGI offset directly: a SHGI of 7 adds around 11°F on top of feels-like temperature — the number that determines whether you need sun protection, arm warmers, or both.


🌧️

Smarter Precipitation Color Coding

The precipitation column is colored by cycling impact — type and amount — not just probability. A 10% chance of hail is categorically different from a 40% chance of drizzle, and for cyclists, surface conditions like ice and standing water matter more than getting wet.

Solid precipitation (snow, sleet, hail) triggers red at any non-zero probability — no gradient, no ambiguity. Rain uses a two-axis system combining probability and amount, because low-probability heavy rain is more disruptive than high-probability drizzle.


⏱️

Minute Forecast & Radar

Tap the Now row to expand two tools for in-the-moment decisions, where available.

A 60-minute bar chart shows precipitation intensity minute by minute — because "40% rain this hour" doesn't tell you whether it's raining now, easing off, or about to start in eight minutes. The chart answers the question cyclists actually ask: do I stop and put my jacket on now, or push through? When rain is detected, the pane opens automatically.

Below the chart, a live radar map shows current NEXRAD composite reflectivity for US locations. A grey dot marks the forecast location; a pulsing blue dot shows your live device position, updated every 30 seconds. On a saved location page this tells you exactly where you are relative to the storm cell you're watching.


⚠️

Cycling-Specific Alerts

CycleWeather evaluates conditions against a set of cycling-specific thresholds and surfaces alerts in a pane above the forecast.

Safety-tier alerts are always visible: active thunderstorms, freezing rain, dangerous wind gusts with actual gust speed, and government-issued severe weather warnings with a link to full details.

Lower-tier alerts cover conditions that change a ride rather than end it — imminent rain, fog reducing visibility, extreme heat, and black ice risk. The black ice model estimates road surface temperature from air temperature and humidity, and flags the marginal zone where ice can form even when the air temperature is above freezing. These alerts are collapsed by default and expand with a tap, so the safety information is never buried.

Color Coded at a Glance

Every data column — temperature, precipitation, wind, air quality, UV, and solar heat gain — is color coded so you can assess conditions instantly. Green means go, and the colors shift through yellow, orange, and red as conditions become less favorable for riding. No numbers to parse, no forecast to interpret — just look at the colors.


📍

Your Locations

Save up to 10 favorite locations and swipe between them in the forecast carousel. Your current GPS location is always the first page, just tap the GPS button on the top left to jump to it. Check conditions at the trailhead, the group ride start, a destination city — all without re-entering locations.

Tap the city name to search anywhere in the world. Searched cities appear as a temporary page; tap the star to save as favorite. Drag to reorder saved locations in the search sheet; the order is reflected in the carousel. Swipe left in the search sheet to remove cities from favorites or recents.
