Good points H_M,
However it should also be noted that a lot of the rain we experience here is very "localised" so places further afield, such as Cartagena and Murcia will probably not be affected.
As H_M also mentioned it rained heavily this week, which is not unusual for our micro climate here.
When this type of rain does occur, the very last thing you will be thinking about is venturing out of the house. We don't have the usual road drainage systems that are necessary in the UK, so any form of driving is dangerous to say the least and only advisable if absolutely necessary.
That being said, there are alternative activities to participate in assuming you can get there.
The cinema in Las Velas shopping centre (on the way to San Javier airport) has started to show films in English.
The Polideportivo (sports centre) in Los Alcazares has indoor facilities, as well as the brand new leisure centre in Los Narejos, on the way down to the beach just past Varazul.
In the winter months of Dec and Jan there is an ice scating rink in Cartagena.
All of this information can be found at the tourist information center opposite the Wok Buffet/Barclays bank shopping area, or you can visit the Murcia tourist board by using this address, without the spaces w w w . murciaturistica . es / en / tourism . home
It's all in English :)
Have fun while your here :)
Regards,
Paul
