Parts of Western Australia's southwest soaked up some reasonable rain overnight and have now exceeded the seasonal average, but there is not a lot more on the horizon. Much of the region, including parts of the wheat belt, picked up some rain overnight as a front moved through. However, there was very little inland as it focussed on the coast. Just south and east of Perth, Dwellingup and Bickley have accumulated their average spring rain, only half way through the season. Dwellingup gained 14mm overnight and has just over 270mmm for the season so far, compared with the spring average of 257mm. Bickley in the Perth hills has had about 238mm so far with help from nine millimetres overnight, and has now just bypassed its spring average. Troughs and fronts have not contained a huge amount of moisture but been relatively frequent so far. Dwellingup has had rain on 31 days already this season, only seven days fewer than the spring norm. The lack of moisture in recent systems has meant that Perth and the wheat belt are now falling short of their average rainfall after a wet September. Perth only picked up four millimetres overnight, taking it to eight millimetres for the month. This is well short of the 52mm monthly average and we are entering the drier end of the month. Northam in the wheat belt had its first rain for the month overnight and it was less than a millimetre, still 24mm short of the October average. Looking ahead, the lack of soaking rain looks set to continue for the rest of the month. Sea temperatures off the west coast have cooled recently, reducing moisture in the air. Only patchy falls are likely in the next few weeks and these will generally be light.
