The rainfall distribution is seasonal. Dominant rainfall is usually in the summer season
when more than 65% of the average annual rainfall is received. During the summer
rainfall intensities are high, with rainfail reaching a peak during February and March. The
driest months are usually July, August and September.

The micro climate for Attunga Heights can differ from that recorded at Tewantin. Moreover,
the monthly rainfall averages do not reflect the variations which occur between different
years. Nevertheless, they give a general picture of the prevailing climate.

These tables confirm the difficulty the subject land and surrounding area has in generating
sustained bad fire conditions because even in August, September and October, there are
6-8 days of rain each month. This makes cured fuel difficult to develop and as such the
potential for a high intensity fire is low.

As previously stated, history shows that bad weather and seasons wilt occur in the once
every 10-12 year category and then usually for short duration (1-2 days). This means that
when a dry spring and summer presents itself, extra care is needed.
