Typhoon approach calendar for Hokuriku
Period: finalized records for 1951–2025 (75 years)
The Japan Meteorological Agency (JMA) normal (1991–2020) is 2.8 per year, on the low side for the main islands. In the 1951–2025 records, even this region on the Sea of Japan side has a sizable number of approaches, centered on August (107 days in total) and September (92 days).
Figures in the text are based on records collected as of September 2026 (1951–2025 totals).
An "approach" is counted on each date when the center of a typhoon came within 300 km of any staffed weather station in Hokuriku, following the JMA definition. Preliminary values for the current year are not included.
These are statistics compiled from observations for 1951–2025 (75 years), not a weather forecast for any particular day. For the latest forecasts, see the JMA website.

Total approach days are the sum of approach dates over all years. A typhoon that approached on 2 days counts as 2 days. Bar lengths are relative to the month with the most days in each column. The 2 columns cover different numbers of years, so compare lengths only within the same column (they still show in which month the peak falls). The JMA normal (1991–2020) for annual approaches to Hokuriku is 2.8.
