Areca Palm clusters planted over 13 years ago by me and neighbor. They have grown to over 12' high with 4" stalks. Fonds are huge.
With last January 4 night freeze, there was severe, almost half, die back. Over the year there has been normal growth.
Problem- Fronds are growing to normal length, tips of frond leaves are opening but they turn brown quickly before a full opening of the frond and development stops.
We have been experiencing a drought in the area the last few years. Not enough water? Not enough fertilizer? Missing minerals? Too much freeze for recovery?

Consider these possibilities.
Palms are extremely sensitive to salts. Salts cause browning of fronds and leaf tips of other plants too. If you don't water thoroughly and deep enough you can get a salt build up on the root system causing the roots to burn and the fronds to turn brown. Commercial fertilizers are also salts and if not applied correctly or watered correctly they can also cause the burning of roots and browning.

Cold/frost damage usually results in black/brown leaves or fronds. After a year as stated any cold or frost amage should have disappeared.

My thought is your situation is water related. Florida soils are high in salt content.

Would this also cause damage to inside house palms? I just placed my palm inside untill it gets warm again. My palm fronds are turning brown and the leaf tips of the new ones are starting to turn brown as well. I don't know if I am watering it too much or not enough. I figure not enough as it is very dry inside with the heat running all the time.

More than likely, yes. Overwatering will primarily cause your symptoms. But again you could have a salt situation. Salts do build up periodically in potted plants and should be flushed out every once in awhile to get rid of the salts. I flush my potted palm plants out about every 5th or sixth watering, then let them nearly dry out before watering again.
Some types of tropical plants need to remain moist, not wet, all the time, yet they'll need a flushing out periodically. Again black tips usually means salt/fertilizer burn, brown only overwatering.
If you're not sure about watering cycles, purchase a Moisture Meter, @$6.00 at a Garden Center. They take the guess work out of watering and will give you a idea of the water cycle your plant requires. Stick the probe into the plants soil at 2 or 3 places and it will tell you what's happening as far as wet, dry, or normal. You don't leave the probe in the pot. Use it for all of your plants inside or outside.
