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 tropical_cyclones@metoffice.gov.uk. At the end of the season a verification report on the performance of the Met Office global model will be published.
Name & ID | Start & end dates | Central pressure, 1-/10-minute MSW | Comments on Met Office global model forecasts |
---|---|---|---|
Ancha (01S) | 01-04 October | 992 mb, 50/45 knots | The track of Ancha was well predicted with a slight slow bias. |
Bheki (02S) | 14-22 November | 943 mb, 115/105 knots | Track forecast errors were mostly low, except at long lead times due to a right-of-track bias in early forecasts. |
Chido (04S) | 09-16 December | 935 mb, 135/115 knots | A slow bias at longer lead times resulted in large track forecast errors. |
Dikeledi (07S) | 09-17 January | 945 mb, 100/95 knots | There was a slow and left-of-track bias resulting in large track forecast errors. |

---|---|---|---|
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. |
Name & ID | Start & end dates | Central pressure, 1-/10-minute MSW | Comments on Met Office global model forecasts |
---|---|---|---|
06P | 29-30 December | 997 mb, 50/30 knots | 06P was a short-lived storm. |
Pita (08P) | 10-12 January | 993 mb, 40/35 knots | Pita did not last long, but track forecast errors were large due to a slow bias. |
Western Australian observed tracks in 2024-25
Eastern Australian observed tracks in 2024-25
Name & ID | Start & end dates | Central pressure, 10-minute MSW | Comments on Met Office global model forecasts |
---|---|---|---|
14-16 December | 998 mb, 40 knots | Bigua was short-lived as a subtropical storm. |
South Atlantic observed tracks in 2024-25
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.
