[ A 'Hot spell' is defined here as a period of 3 or more days when the maximum temperature reached or exceeded 25degC : The record starts in 1999, but at various points the temperatures are noted only to the nearest 0.5degC. The highest temperature reached in any individual spell is emboldened, and the values >=28degC are highlighted in colour. Total numbers of days >=25degC and days >=28degC are annotated appropriately.]

[ Defined here as a period of 24hr when the minimum temperature failed to fall below 16degC - note carefully that this is not the same thing as a 'warm night', because sometimes the night minimum can be above 16degC, but the overall 24hr minimum for the particular day can be below: The record starts in 2000, but at various points the temperatures are noted only to the nearest 0.5degC. The highest temperature in any individual spell is emboldened, and the values >=18degC are highlighted in colour. Total numbers of days >=16degC and days >=18degC are annotated appropriately.]
