Observed and forecast tracks: northern hemisphere 2025
A summary of tropical cyclone activity in the Northern Hemisphere for the 2025 season together with an assessment of the performance of the Met Office global model in predicting the track and intensity of these tropical cyclones.
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.

Mediterranean observed tracks in 2025
Note on estimated wind speeds
1-minute MSW: Maximum sustained wind (knots) averaged over 1 minute (JTWC Hawaii, NHC Miami, CPHC Hawaii)
3-minute MSW: Maximum sustained wind (knots) averaged over 3 minutes (IMD New Delhi)
10-minute MSW: Maximum sustained wind (knots) averaged over 10 minutes (JMA Japan)
Note: Although 1-minute average winds should be stronger than 3-/10-minute averages, this may not be the case here since estimates are obtained from different warning centres using different analysis techniques.
