The update to HadISD v3.4.1.202409p has just been released, now that the data services at NOAA NCEI are back online following the flooding from Hurricane Helene. Although many files are updated through to 30 September 2024, it is possible there are some data gaps resulting from missing ingested data. NOAA NCEI are working through these, but it could take a while for all data gaps to be filled. More may be apparent in the next release (v202410p).
It is also not yet clear if the date scheduled for the termination of updates to the ISD (31st October 2024 as last I heard) will now move later. We intend to continue updating HadISD for as long as updates are appended to the ISD.
