Monthly data --- chart/table

Note: The Tokyo surface observation site was relocated on 2 December 2014. In this connection, climate normals for monthly mean temperatures at the Tokyo site were updated. Accordingly, monthly mean temperatures and monthly means of daily maximum/minimum temperatures for the period before December 2014 at the site are not shown in the ClimatView. The climate normals for monthly total precipitation amounts remain the same after the relocation, which is described in further detail here.

Detailed historical monthly data in Japanese stations are available at: Historic Monthly Values

Note) Background colors of the Standardized Precipitation Indices (SPIs) cell in the table are changed in accordance with the degree of dryness only when the values become below -1.0. It is noted that the SPI value with -9999 (9999) will be displayed in the case of extreme low (high) precipitations where occurrence frequencies of such event are significantly small during a certain period. "Occurrence frequencies are significantly small" means cumulative probability equals zero (one) or is very close to zero (one).
