Your co-pilot for weather on the road

For each of the 6 points, we show temperature, chance of rain, wind and expected weather condition for the exact time you pass through — not the generic forecast for the nearest city. That way you know if you'll hit sun, drizzle or a storm ahead.

Next to the route result, RotaClima simulates the same trip leaving now or postponed by up to 12 hours, checking the weather every 30 minutes. To keep the screen clean, the time bar only shows the times where the weather actually changes from one slot to the next — if nothing changes, you just see a notice: "No significant weather changes in the next 12 hours" when conditions are fine, or "Continuous rain expected for the next 12 hours" when there is no dry-road window. When there is variation, each time shows the departure, the estimated arrival, the expected rainfall and a label that matches the real condition: dry road (no rain), light drizzle (up to 1.5 mm), moderate rain (1.5 to 8 mm), heavy rain (over 8 mm or a storm), fog or strong wind — never a label that contradicts the millimeters shown. The indicator color marks severity: blue for calm conditions, amber for caution and red for severe conditions. A star marks the best window: the one with the least real rain wins; on a tie or a negligible difference (under 2 mm with no condition change), the star stays on the time closest to your planned departure — a later time only earns the star when it truly improves things, like going from rain to a dry road. Tap another time to see the map, stretches and alerts update instantly, without searching again.

Save your two usual addresses once — neighborhood, street with number or ZIP code, always with the city. From then on, the home page shows two 1-tap buttons: Go to work and Head back home, always calculating the forecast for someone leaving now. On urban trips (up to 50 km), the timeline points show neighborhoods and avenues instead of repeating the city name. The departure time simulator still applies: if a downpour passes in 40 minutes, the star marks the best time to leave — perfect for deciding whether to pack the raincoat or wait for the break before heading home. Your addresses are stored only on your device. Once the commute is saved, the Heads-up before you leave card appears: pick your usual departure time and the days of the week, and RotaClima checks the forecast for your way and warns you 30 minutes ahead — but only when meaningful rain is expected, never every day for no reason. The alert arrives as a phone notification (Android, desktop and iPhone with the app added to the Home Screen) or by email, which works on any device, including older iPhones. No account required: the alert is tied to your device, and you can change the time or turn it off with one tap.

Every Friday at 9am (Brasília time) RotaClima sends a short bulletin reminding you to check the road before your weekend trip: "Hitting the road this weekend? Check your route forecast on RotaClima." The invitation shows up right after your first route search — just tap Turn on alerts and allow the notification; if you prefer (or use an older iPhone), enter your email and get the bulletin there. No account required: the permission lives on your device, and anyone who already turned on the daily commute notification gets the Radar automatically. One message per week at most — no repeated pings.

At the top of the result there is a Share route button. Tapping it makes RotaClima create a dedicated address for that trip on our own domain (rotaclima.app/rota/…) and open your device's share menu with the text ready: origin, destination, departure time, distance and the link. On a computer the text is copied automatically and you get a WhatsApp shortcut. Whoever receives it opens the link and lands straight on that trip's analysis — summary, main concern, weather along the route, map and alerts — always with the forecast refreshed at the moment they open it. In messaging apps and social networks the link already shows a preview with origin → destination. No account data, live location or personal information is stored in the link.

The Rain today button, in the top bar of the home page, opens the hyperlocal forecast for the next 12 hours wherever you are — no route needed. Tap Use my location to allow GPS once, or type your neighborhood or city; the app remembers your choice on your device and opens straight into it next time. The first line gives you the straight answer: “No rain expected in the next 12 hours”, “Raining now — dry break from 6 PM” or “Shower expected between 4 PM and 5:30 PM (up to 4 mm)”. Below, the hour-by-hour ruler shows each hour with temperature, condition and expected millimeters, color-coded by intensity: gray for dry weather, blue for drizzle, amber for rain and red for storms. The data comes from the European ECMWF model, the same one used for route forecasts — perfect for deciding when to leave home, go to lunch or hit the gym, even on days you're not on the road.

We analyze every stretch and flag severe conditions: storms, heavy rain, fog, snow and strong winds. You get a clear warning before leaving home, with the stretch and approximate time the condition appears.

We mark nearby gas stations on the map, with name and a direct link to Google Maps. Plan your refueling stops without leaving your route.

When there are viable paths, we show up to 3 route options side by side, with distance, travel time and the weather on each. Compare and pick the safest one.

You can choose between two models:

• Automatic — combines regional models, more detailed for Brazil.
• ECMWF — the reference European global model, the same one used by apps like Windy. Great for long routes and an overall view.

The route is drawn on the map, with numbered markers at each of the 6 points and at gas stations. Road names are shown so you know exactly where you're going.

Below the route result you see mobile coverage stretch by stretch. Each segment is classified as good signal, weak signal or no record — the latter means a possible dead zone. In Brazil we use the official Anatel station database; outside Brazil we combine data from OpenStreetMap and the OpenCelliD community. You can filter by technology (2G, 3G, 4G or 5G) and, by tapping the kilometer boxes below the map, the app zooms to that exact stretch to show nearby antennas. It is an estimate based on antenna density, not a real-time signal measurement.

Broke down mid-trip? Roadside Support finds motorcycle and car mechanics, tire shops, dealerships and tow trucks within a 5 km radius of your position — with phone, opening hours and a shortcut to open in the map. It also lists highway emergency phone numbers.

Traveling in a group? Create a convoy and send the invite link via WhatsApp. Every member shows up on the radar with a nickname and a position updated every minute; anyone without a signal for a few minutes fades on the map. The room expires by itself after 48 hours without movement.

The route RotaClima calculates is still the best paved route — nothing changes for riders who only want asphalt. Below the result there is an Adventure mode (off-road) button: tap it and the app looks for sights mapped within 15 km of your travel corridor (viewpoints, waterfalls, peaks, parks, historic monuments and wineries) and draws, for each one, the access path starting from the highway — always leaving from a real point of your route, never a stretch floating on the map. On the single map the highway turns blue, the access is dashed orange where it is paved and green where it is a dirt road, with a 📍 pin at the turn-off so you do not miss it. Tapping the line or the pin shows the summary: how many kilometres to the place, how much is paved and how much is dirt, the km of the route where the detour starts and the estimated passing time. The differentiator is the ground alert on the dirt parts, crossing forecast rain with the previous 12 hours of rainfall at your exact passing time: firm ground (dry) in green, damp ground in amber and mud warning in red. There is a golden rule: every sight along the trip is shown — tap any of them, on the map or in the list, and the app instantly draws the way from the highway to it, with paved and dirt stretches in different colours. When the final stretch is a track or raw ground, a warning shows: rough final stretch — best for trail bikes or 4x4. The list below the map is grouped by the town each place belongs to, in travel order — from the nearest town to the farthest: tap a town's name to open it and see every sight there, with the highway kilometre and the detour distance. Tapping a sight draws the way on RotaClima's own map and zooms straight to the turn-off, showing where pavement becomes dirt. One tap on Back to the paved route restores the original screen — the paved route is never replaced unless you ask. The OpenStreetMap lookup uses the same light, fast mechanism as fuel and tolls: the app first checks which servers are up, runs short searches and keeps the result for 7 days — so the same region opens almost instantly the second time. Long trips can bring hundreds of highlights: use the quick distance filters (all, up to 5 km, up to 10 km and over 10 km) and the Show more button to browse without clutter, while the map groups nearby points into circles with a count — just zoom in and they split into individual pins. Dirt roads change fast: use this for planning and assess conditions on site.

Forecasts come from public third-party sources — Open-Meteo, the ECMWF model and OpenStreetMap — and may differ from observed weather. They are estimates for planning and should not be the sole basis for safety decisions.
