By late August, the days become hotter, though the nights are still cool and by October the days are very hot, with warm nights. It is still dry. The rainy season starts in December, so this month can be very humid. In cities and southern tourist areas, direct international dialling is available. Further up north, communication can often be cut off due to weather conditions, and many of the hotels and lodges in remote areas use only radios, and satellite phones for emergencies.
National calls are cheap.
Fax and internet facilities are also becoming widely available in major towns. A variety of plugs are in use, most modern buildings have square 3-pin plugs. Other than in the bigger cities, most hotels and lodges run on generators so there may not be plug sockets in your rooms. Often the generators are stopped at night and if so, torches and candles are provided. Your own torch could be useful.
