A Discussion of TAF Cycles

In the U.S., TAFs are produced four times a day starting at approximately 30 minutes before each main synoptic hour (00Z, 06Z, 12Z, and 18Z). All the forecasts produced starting one hour before the main synoptic hour up to four hours past the main synoptic hour are considered to be for the same cycle. For example, forecasts produced between 1100Z and 1600Z are all considered to be 12Z forecastss. In reality, forecasts contain the starting and ending times for which the forecast is valid. Our rule of thumb is that all forecasts produced between (hh-1)00Z to (hh+4)44Z are considered to be for the hh cycle. The following table summarizes the relationship between forecast production time and cycle:
