How this is worked out: a month qualifies when its mean daytime high falls between 18 °C and 27 °C. Where more than five qualify, the answer is the driest run of consecutive qualifying months; where none do, it is the driest three months in a row if the year is hot throughout, or the warmest three if it never gets there. The figures are the thirty-year monthly averages charted below, and they are averages, not a forecast — any single year can miss them by a wide margin.
