Turbulence Forecast Tools Compared (2026): Turbli vs Turbcast vs Turbulence Forecast vs SkyBriefing
An honest, side-by-side comparison of the consumer turbulence-forecast tools available in 2026 — features, data sources, pricing, and where each one fits best.
Turbulence forecasting used to be something only airline dispatchers and pilots had access to. In the last few years, a small but capable set of consumer tools has emerged that surface the same underlying atmospheric data to anyone with a flight booking. This article compares the main options as of mid-2026.
This comparison is published by Turbcast, one of the products being compared. We've tried to write it fairly. Where Turbcast is genuinely better, we've said so; where another tool is genuinely better, we've said that too. If you spot something we got wrong about a competitor, email info@turbcast.com and we'll correct it.
The tools
| Tool | Founded | Pricing | Best for |
|---|---|---|---|
| Turbli | 2020 | Free | Polished consumer experience, broad reach |
| Turbulence Forecast | 2007 | Free + paid subscriptions | Pilot-written forecasts, depth of analysis |
| Turbcast | 2024 | Free + USD$10 alerts | Per-flight-number lookups, route-segment detail |
| SkyBriefing | 2021 | Free | Pilot-curated content, fear-of-flying focus |
| ZeroTurb | 2023 | Free | Live global turbulence map |
What they all have in common
All five tools draw, at the base layer, from the same public source: NOAA's World Area Forecast System (WAFS) turbulence forecast. WAFS is updated every 6 hours and is the international standard used by airline dispatchers. None of these consumer tools runs its own atmospheric model — that would require supercomputer time none of them have.
What differs between them is:
- What they layer on top of WAFS — physics indices, live PIREPs, route-segment computation, presentation.
- What they leave out — some tools simplify the picture for nervous flyers; others expose more detail.
- How they monetize — free, freemium, donation-supported, or paid.
Turbli
Turbli is the longest-established and best-known consumer turbulence tool. It launched in 2020 and has become the default reference for travel journalists.
Strengths: mature, polished consumer experience; strong brand recognition; free with no signup; clear visual presentation of forecast severity.
Limitations: single composite severity score per route — no per-flight-level breakdown; doesn't support flight-number lookups (you need origin/destination/date); no paid alerts; no notification when forecasts change close to departure.
Best for: Travellers who want a quick yes/no answer on whether their route is statistically bumpy.
Turbulence Forecast
The oldest of the consumer tools, founded by a commercial pilot in 2007. Blends human-authored forecasts with automated data.
Strengths: hand-written forecasts for major transatlantic and transpacific routes; strong pilot/aviation-community trust; PIREP-rich; active community elements.
Limitations: some content gated behind subscriptions; older visual presentation; selective coverage (best for major long-haul corridors).
Best for: Aviation enthusiasts and frequent long-haul flyers who want depth of analysis.
Turbcast
(This is our product. We've tried to describe it as accurately as we describe the others.) Launched in 2024, focused on free, fast, no-signup access and per-flight-number queries.
Strengths: flight-number lookups (type "NZ1" or "BA009"); per-segment route breakdown; per-flight-level forecasts (FL240 / FL300 / FL340 / FL390 / FL450); free, no signup, no email; optional USD$10 one-off alert (no subscription); physics-based layer on top of WAFS (Ellrod TI1, Richardson, CAPE); per-airport and per-route landing pages.
Limitations: newer brand; no hand-written analyst commentary; no native mobile app yet (web is mobile-responsive).
Best for: Travellers who know their flight number and want a quick, detailed, no-signup forecast — or who want a verified PDF briefing.
SkyBriefing
A free pre-flight briefing tool by an airline pilot. Blends forecasts with fear-of-flying education.
Strengths: calm, reassuring tone; pilot-written explanatory content; free; clean interface.
Limitations: less depth than Turbulence Forecast; less per-flight precision than Turbcast; smaller global coverage.
Best for: Anxious flyers who want a forecast plus reassurance.
ZeroTurb
The newest entrant, launched 2023, differentiated by a live global turbulence map UI.
Strengths: strong visual; useful for general atmospheric awareness; free.
Limitations: less per-flight specificity; newer brand; map-first UX may overwhelm casual users.
Best for: Aviation enthusiasts and weather-curious users.
How to choose
If you have one flight and want a quick read:
- You know your flight number → Turbcast
- You only know origin/destination → Turbli
If you're an aviation enthusiast wanting depth:
- → Turbulence Forecast for analyst commentary
- → Turbcast for per-flight-level technical detail
- → ZeroTurb for the global-map view
If you're a nervous flyer:
- → SkyBriefing for pilot-authored reassurance
- → Turbcast's is turbulence dangerous and will turbulence crash a plane for the engineering safety picture
If you want a PDF briefing in your inbox:
- → Turbcast is the only one with a one-off paid alert (USD$10, no subscription)
Notes on accuracy
All five fundamentally rely on NOAA WAFS for the base turbulence layer. Published verification — Probability of Detection ~75%, False Alarm Ratio ~30% for moderate-or-greater turbulence — applies to all of them at the shared layer. Differences come from how they layer physics on top, whether they incorporate live PIREPs, how they handle changes between 6-hour cycles, and how they present uncertainty.

What's not on this list
- FlightAware, FlightRadar24: Excellent for live aircraft tracking. Turbulence overlay is secondary to their core function.
- MyRadar: Consumer weather radar app with limited turbulence-specific information.
- iOS "Turbcast" app (separate product from this site): A fear-of-flying education tool built around NLP techniques by a different team. Not a forecast tool per se.
The bottom line
You can't really go wrong with any of these — they all use the same underlying NOAA data. Pick the one whose UX fits how you want to engage with the forecast. The good news is they're all free at the layer that matters.

Can Pilots See Turbulence on Radar?
Weather radar can spot the thunderstorms that cause convective turbulence — but it is essentially blind to clear-air turbulence, the kind that injures most passengers. Here is what pilots can and cannot see, and what they rely on instead.
