Observed and forecast tracks: southern hemisphere 2024-25
All tropical cyclones in the southern hemisphere season in 2024-25 are listed below including details of their start and end dates, lowest central pressure and maximum sustained wind (MSW).
Click on the name of the tropical cyclone to see a chart of the observed track and forecast tracks from the Met Office global model. Verification statistics on each tropical cyclone are available upon request from [email protected]. At the end of the season a verification report on the performance of the Met Office global model will be published.

| Vince (13S) * | 01-12 February | 930 mb, 135/115 knots | Track forecast errors were mostly below the recent mean apart from for long lead times, due to a left-of-track bias. |
| Garance (22S) | 25 February - 02 March | 951 mb, 105/95 knots | At short lead times track forecast errors were near to the recent mean values, but much lower at longer lead times. |
| Honde (23S) | 25 February - 05 March | 968 mb, 70/65 knots | Early forecasts had large track errors at longer lead times, but other forecasts mostly had errors below the recent mean values. |
| Ivone (24S) | 08-14 March | 981 mb, 50/50 knots | At long lead times track forecast errors were well below the recent mean values. |
| Jude (25S) | 08-16 March | 970 mb, 80/75 knots | At most lead times track forecast errors were below the recent mean values, although there was a left-of-track bias. |
* Taliah and Vince originated in the Australian region

| 27-29 November | 985 mb, 55/55 knots | Track forecast errors were a little above the recent mean values. | |
| 05S | 26-29 December | 998 mb, 35/35 knots | 05S was short-lived. Track forecast errors were low. |
| 09S | 09-10 January | 1003 mb, 35/30 knots | This was a short-lived storm with few forecasts verified. |
| Sean (10S) | 18-23 January | 945 mb, 115/95 knots | Track forecast errors were mostly very low for this cyclone. |
| Taliah (14S) * | 01-18 February | 965 mb, 85/75 knots | Track forecast errors were close to or below the recent mean values for this long-lived storm. |
| Vince (13S) * | 01-12 February | 930 mb, 135/115 knots | Track forecast errors were mostly below the recent mean apart from for long lead times, due to a left-of-track bias. |
| Zelia (17S) | 11-14 February | 928 mb, 130/110 knots | Track forecast errors were low, although the landfall location was farther east than predicted. |
| Alfred (18P) | 22 February - 08 March | 951 mb, 115/90 knots | Despite having a slow and right-of-track bias in several forecasts track forecast errors were below the recent mean values at most lead times. The sharp turn westwards towards landfall over Australia was well predicted by all forecasts. |
| Bianca (20S) | 23-26 February | 958 mb, 100/90 knots | Short lead time forecasts were good, but there was a slow bias for longer lead times forecasts |
| 26S | 18-21 March | 991 mb, 45/45 knots | Few forecasts were verified for this short-lived storm, but track forecast errors were above the recent mean values. |
| Dianne (28S) | 26-29 March | 989 mb, 45/40 knots | Dianne was short-lived, but the landfall was well predicted. |

Note on estimated wind speeds
1-minute MSW: Maximum sustained wind (knots) averaged over one minute (JTWC Hawaii)
10-minute MSW: Maximum sustained wind (knots) averaged over 10 minutes (Southern Hemisphere RSMCs and TCWCs)
Note: Although 1-minute average winds should be stronger than 10-minute average, this may not be the case here since estimates are obtained from different warning centres using different analysis techniques.
